Anywhere Management Center

Configuration Sections

The MindLink Management Center will load with the Licence configuration as its default page. The user can navigate through different configuration settings by using the navigation tree on the left, which includes the following configuration sections:


The licence page ensures the products you are using are supported by MindLink and that only the correct products (as stated by contract) are in use. Once you install a product's management center the License tab will be the first tab you see. Each Management center requires a valid license file to be provided.

MLA License tab MLA License page

License File

MLA License Details for 100 users

The Browse for license file... button opens a file browser window, from which you select the licence file provided during your purchase of the MindLink Product(s); This will be the file you received within the correspondence with your account manager.

Once the file is selected the details will populate as long as the license is valid.

License errors
If the license is not accepted there will be an error message that indicates the cause of the issue. Please contact your account manager to receive a current license within contract renewal.

License Details

MLA License Details for 100 users

Selecting a valid license file will populate the details section with the license information.

  • License holder: This field specifies the Company name the license is issued to and also the product owner at the time of purchase.

  • Expiry date: The date the product expires. At this time (grace period built in) the product will cease to function.

  • Details: This field contains the product/s that the license has been issued for. MindLink will not run with an incorrect product license (a single license can be issued for multiple products).

Enabled users

MLA License Details for 100 users

This capacity is based on the number of users who could log on, rather than the current number of users logged on.

The system periodically checks the number of users who could log on and starts rejecting new logins if it sees that the number of hypothetical users is larger than the licensed capacity.


MLA Logging tab

The logging section enables the user to configure the logging level as well as the log file location for the Connector Service.

Please note that logging on the Connector Service is performed using the Microsoft Enterprise Library Logging Application Block.


Logging Level

By default logging is configured as follows:

  • Error level - Error class events
  • Warning level - Warning class events (Recommended)
  • Info level - Info class events
  • Verbose level - All class events

Log file location can be set by Clicking on the Browse button, where an absolute path to a new log file location can be chosen, or you can manually edit the field to a path relative to the Connector Service install location.

The account used to run the Connector Service must have write access to the install location of the product in order to log to the rolling log file. By default, the file can be found at %ProgramFiles%\MindLink Software\MindLink Application\ConnectorService\Logs\Connector.log

Enable audit logging enables audit logs for every user interaction on the chat system.

Add advanced logging configuration to record user logins in a separate file
The Advanced tab allows key/value pairs to be used to configure additional logging functionality

See the Advanced section for details


The General section lets the user configure the general settings that will be applied to the Connector Service.

MLA General tab

File Transfers

MLA General tab

Maximum concurrent downloads: The maximum number of allowed concurrent file download requests.

If an attempt is made to download a file when the number of active file downloads to the server is equal to the number specified, the download will fail with an error indicating that the server limit is currently exceeded and to try again later.

Maximum concurrent uploads: The maximum number of allowed concurrent file upload requests.

If an attempt is made to upload a file when the number of active file uploads to the server is equal to the number specified, the upload will fail with an error indicating that the server limit is currently exceeded and to try again later.

Maximum file size for file uploads: If the configured connector supports file posting, the maximum size of files in kilobytes allowed to be uploaded.

If an attempt is made to upload a file that is larger than the specified size, the server will return an error indicating that the file is too large to upload.


MLA General tab

Enable instant messaging:
When set, allows connected clients to use one-to-one messaging. When not checked, user presence will not be published, instant messaging will be disabled, and the client will be limited to group messaging functionality. Any client that exposes instant messaging functionality when instant messaging is disabled will receive failure notifications from the server when an attempt is made to use such functionality.

MindLink Requires at least one chat modality - instant messaging or group chat - to be enabled

Enable group chat:
When set, allows connected clients to use group chat. When not checked, group chat preferences are not loaded and users will not see any groups or chat rooms to which they are subscribed in their contacts list nor will they be able to search for and add groups.

MindLink Requires at least one chat modality - instant messaging or group chat - to be enabled

Allow user to disable instant messaging

When set, allows users to specify whether they want to log on with or without the group chat capability enabled on their web or mobile client. When not checked, users will not be able to choose to enable/disable group chat upon login and the setting will default to the configuration in the management center .

Enable file transfers in 1-1 conversations
Allows users to upload files into IM conversations. This functions the same as file uploads into Group Chat conversations, supporting most file formats. Images, Text files, PowerPoint, videos, Excel files and .PDF files are all supported, among other file types. Any file upload must comply with the size restrictions configured in the File transfers section above.

Enable audio calls
Enables audio calls in MindLink. The call option will be available in IM conversations, as one-to-one calls, and in Multiparty conversations as a conference call. Both call types are cross-platform compatible with the native Skype for Business clients.

More information can be found on the Voice Troubleshooting page.

Enable setting profile pictures
Allows user to set profile pictures in the web client.

Users can add, change or remove profile pictures through the MindLink client itself. This functionality must be enabled in the management tool first and allows a user to make changes from their contact card. When configured, a 'Upload photo' button will be showing on the contact card.

When not check profile pictures can be view in the MindLink client, but users are not able to set a profile picture.

Message Constraints

MLA General tab

Maximum message length: The number of characters that a single message can include.
If an attempt is made to send a message that is longer than the specified length, the server will automatically convert the message to a Story.

Maximum story length: The maximum number of characters that a single story can include.
If an attempt is made to send a story that is longer than the specified length the server will not send the message and will return an error indicating that the story exceeded the maximum allowed length.


These are special panels that appear below the chat input in chat rooms. The system administrator configures which panel appears in which chat room using the Group Chat Administration Tool.

Add-ins are entirely optional and do not need to be configured to deploy MindLink Anywhere.

MLA Addins tab icon

Client Add-Ins are web pages hosted inside the Group Chat Console client, which communicate with the parent window using JavaScript.

MindLink Anywhere hosts each Client Add-In inside a Html IFRAME element within the MindLink Anywhere page. The Client Add-In can communicate with MindLink Anywhere using the same JavaScript calls as in the Group Chat Console client.

However, to enable this communication to happen, both MindLink Anywhere and the Client Add-In page must be served from the same domain and port address. This is a standard security requirement enforced by all browsers.

For instance, if MindLink Anywhere is served from Anywhere, then for any Client Add-In to be shown in MindLink Anywhere it must also be served from a relative path on e.g.

In an enterprise environment, it is often not the case that MindLink Anywhere and any Client Add-Ins will be served from the same actual machine. Hence, they will be served from different domains/ports and so Client Add-In/MindLink Anywhere communication will be forbidden. The use of a reverse-proxy is therefore required to mux requests to MindLink Anywhere and to any configured Client Add-Ins to the same domain. See the Prerequisites page to Configure Add-in Proxies

Skype for Business

The Adaptor section manages the selection of the underlying chat system to which to connect and the infrastructure DNS servers that define the chosen platform.

MLA Network tab Network

This section is for configuring network connections.
in most scenarios, the default values will suffice, though HTTP Proxy settings may be provided here if required.

Call routing

MLA Call Routing tab Call routing

This section is for configuring connections to STUN/TURN servers for voice call routing.
A configuration here is only required if you enable Audio Calling, and require ICE Server infrastructure.

Group Aliases

When enabled, per-room aliases can be set in chat rooms.
Users will be able to set Alias display names in groups. This will replace the user display name with a custom name of up to 50 characters. The user's actual name will still show below their alias name in smaller, grey text.

MLA Group Aliases tab Group Aliases

Enable group aliases This enables aliases in chat rooms.

Database connection string: Configure the connection string with the following syntax: Server=FQDN SQL server; Initial Catalogue=SQL catalogue; Integrated Security=SSPI

or if you wish to use a Failover SQL partner you could use the following syntax: Server=FQDN SQL server; Failover Partner=FQDN SQL partner; Initial Catalogue=SQL catalogue; Integrated Security=SSPI

Override credentials for this operation If the user running the management center does not have sufficient SQL permissions, then these can be overridden by a set of credentials that have sufficient permission by your SQL administrator.

After adding the credentials for the user, the connection to the database will need to be tested. The management center will display an error if the configuration is incorrect.

Test the connection To check the validity of a relevant SQL database connection string and the override credentials , select 'Test'. The following steps may differ and as such are outlined in the two scenarios listed below.

Once the database connection has been tested successfully, the MindLink service can be started.


MLA Translation tab

Message translation is an optional feature that allows users to translate messages in a conversation from any foreign language into their target language, which they configure on the Logon page.


Enable translation will activate the translation configuration in the following section:

Translation service

Translation service-based URL: This is the URL of the translation service you are using.

API key: This is the key to your translation service used to provide the functionality.

API key HTTP header name: This is the HTTP header name for the API key.

Configuring message translation will show the language picker on the log in page. From here users can select their language preference from the languages provided by the translation service.

Custom Preferences

MLA Custom Preferences tab

The administrator is able to keep a repository of user preferences. This enables the continuation of preferences across group chat sessions. This also allows for the ability to read preferences across nodes.

An example of such a deployment could be a file share across a network. This allows an administrator to store preferences across multiple machines within a network (if required) meaning that changes made on one machine persist across multiple nodes when the same file store is referenced. In this sense, preferences can be stored cross-site.

Custom Preferences

Custom preferences repository location: The pathway in which the preferences are written to, which can be anywhere that is capable of being read and written to; including across networks. If you don't know where to put it the MindLink install directory can be used, as shown in the screenshot.

The Test button will assess access to the provided pathway. In the event the file pathway referenced is not accessible it is possible to either A) change location (in the event it is invalid) OR B) Provision access rights to the service account running MindLink Anywhere, which is a prerequisite to utilising the custom preferences repository. If successful the message "Custom preferences repository location is available" will show.

Also worth noting is the possibility of having preferences persist during an outage such as in an active-passive disaster recovery scenario. If two machines are connected properly and preferences are shared it is possible that in the event machine 1 falls, machine 2 can pick the preferences up without any outage on the user side. Please note that a batch job would have to be setup to facilitate this transference of preferences across the machines

MLA Advanced tab

Behind each UI configuration in the Management Center, a key-value pair is responsible for mapping configuration values to assigned functionality. These key/value configurations are saved to C:\Program Files\MindLink Software\MindLink Anywhere\ManagementTool\staging.config

The Advanced page gives administrators an accessible interface to directly configure key/value pairs in the Management Center.

  • This section is usually used to add new configuration keys for features that don't have an existing UI configuration available yet.
    • In most cases, these take the form of debug keys - a key with debug. at the start.
    • If advanced keys are required for a feature, the documentation will outline each key and the expectations for its value in the respective feature's documentation section.
  • While the Advanced page can be used to configure keys for any of the functionality with a UI configuration, too, it is not recommended and is rarely beneficial.

Custom Settings

Advanced tab

Configuration KeyConfiguration setting value

Configurations are added to the Advanced page as table rows. Each row requires a key and a value, creating a key/value pair.

Some configuration changes require several dependant key/value pairs to complete the configuration, such as MCE or the "Add advanced logging configuration to record user logins in a separate file" scenario below.

Notes when using Advanced Keys
  • Invalid keys will be ignored
  • Invalid values for valid keys are likely to cause the MindLink service to crash on start-up
  • Rows are mutually exclusive: while some features require multiple key/value pairs to set up, you can add other keys on rows between them
    • For ease-of-use it is recommended to keep related keys grouped together.
    • Rows cannot be reordered in the Management Center, but it is possible for advanced administrators to modify the order of advanced keys in the staging.config file directly.
      • For maximum resiliency, creating a backup of the staging.config is recommended before attempting this.
      • The Management center should be closed before modifying the Staging.config file.
      • Advanced keys are saved at the bottom of the Staging.config file, with the format <add key="advanced: " value=" " />
      • Selecting an entire line and cut-pasting it above/below other advanced keys will re-order the Advanced table after changes to the config file are saved and the management center is re-opened.
      • Advanced keys should not be moved out of the assigned advanced key section at the bottom of the config file; reordering advanced keys should remain localized to above/below the other advanced keys.

Advanced Keys and UI configurations - What takes priority?

In a scenario where you have Advanced keys that map to a feature also configured in the UI pages, only one of these can be applied to the final configuration.

There are several factors that determine the final configuration, with the specifics detailed in the dropdown below.
In short, advanced keys will be prioritized if the UI also configures the same underlying key.

  • Manually adding a new key (without the debug. prefix) will be prioritized.
  • Upgrading from a version without a UI configuration to a version with a UI, the key will still be prioritized if it doesn't include the debug. prefix, though the upgrade process should also migrate key's values to the UI and remove the old keys.
  • debug. keys are added to earlier release versions before a UI configuration is released.
    • A key with debug. wont have a UI configuration yet, so it will always be applied.
    • When the UI configuration is added, we remove the debug. prefix from the corresponding key(s). Each key's value will be migrated to the UI automatically and the old debug. keys will be ignored.
Full details for keys' application and upgrade scenarios:
  • Generally, Advanced keys take priority over UI configurations.

    • This happens whenever a key added to the Advanced page is the same as the underlying key of the UI configuration.
    • Advanced keys are applied after the UI configuration on start-up.
    • Key/value migration will take place when upgrading from a version requiring Advanced configuration to a new version that adds a UI configuration (this applies to debug. and Standard keys)
      • Values for old keys will be automatically migrated to the new UI configuration section
      • The old key(s) should be removed from the Advanced page.
  • In the event you upgrade your MindLink version from a version requiring Advanced keys to configure functionality to a newer version that includes UI configuration for that functionality, the results will depend on the type of keys that were used:

    • starts with debug. - If the previous version configured the feature with debug keys, the debug key(s) will be ignored.
      • When adding the UI configuration, the debug. prefix is removed from the underlying key(s).
      • Old debug keys that have been migrated no longer correspond to the feature and will be ignored.
        • If, for whatever reason, a debug key is not removed in the migration (or is added back later) it will be ignored.
    • does not start with debug. - If the previous version configured the feature with standard keys, the key(s) on the advanced page will take priority.
      • When adding the UI configuration, the same underlying key(s) will be used.
      • Standard keys that have been migrated still correspond to the feature and their values will be applied if they remain in the Advanced configuration.
        • If, for whatever reason, a key is not removed in the migration (or is added back later) it will be applied over the corresponding values in the UI.

Add advanced logging configuration to record user logins in a separate file

Several debug keys can be applied that will make the authentication flow log with a context and report authentication success/failure :

  1. The identity that was authenticating
  2. The success/failure result
  3. The reason for the failure

Copy the Key / value pairings into the Advanced configuration table to set up your deployment to utilise a separate file that filters authentication requests. Your advanced tab should look like this:

Advanced Tab Configuration

After saving and starting the service, a log file that outputs authentication results is created and utilised in a default path (C:\Program Files\MindLink Software\MindLink Anywhere\logging.log).


The MindLink Chat Engine provides a secure engine capable of delivering group chat functionality as a Standalone deployment or in parallel with UCMA.

MCE delivers valuable enhancements to security and functionality beyond the capabilities of UCMA groups, while seamlessly integrating with an existing UCMA environment for IM, presence and UCMA group chat.

SfB Group Administration

Group Management Configuration

SfB Group administration allows users to manage Skype for Business groups from the MLA client. To manage groups a few prerequisites will need to be met.

The group administration is enabled on the MindLink Anywhere page in the management tool.

In the dropdown three options are available:

  • Disabled - Disables group administration

  • Integrated inside the application - This adds group management as an option in the users profile menu.

  • External website - This allows users to use an external website for SfB group management.

    • Clicking the Manage Skype for Business groups externally option in the users profile will direct them to the website specified via the SfB Group Management URL option.
    • The text on the Manage Skype for Business groups externally button can be modified by setting the SfB Group Management button description value. Leaving this value blank will mean the default value is used.

External website Configuration


MLA Authentication tab

Password authentication is the default mechanism, where users manually provide their usernames and password.

MindLink also supports Single Sign-On which allows a user to log onto related systems once and not have to re-enter their credentials for each system. Enabling SSO involves the configuring of the adaptor, and may involve extra configuration depending on the type of connector. For all connectors, the client must be told to connect via SSO by checking the Enable SSO box.

There are three protocols which support Single Sign-On:

  • 1. Windows Authentication
  • 2. HTTP Header Authentication
  • 3. OpenID Connect Authentication


MLA Management Center Authentication

Token Issuing Certificate: Select the certificate to use for the Token Issuing Service. It is mandatory that you provide a token issuing certificate, as this is used to manage user authentication. Ensure that the certificate has a key length of 2048 bits and is set up for the digital signing.

Allow users to select the preferred authentication mechanism: Gives the user the ability to select their preferred authentication mechanism. This is only available when more than one mechanism is configured. If more than one authentication mechanism is enabled and the authentication fails then the mechanism will attempt to authenticate with the next mechanism, until all have been attempted.

Desktop Authentication

Password Authentication

MLA Management Center Authentication

Enable password authentication: Enabled by default. When enabled, connecting to the MLA server simply presents a web version of the MindLink Anywhere username and password screen.

Desktop Password Authentication

Windows authentication (NTLM/Kerberos)

MLA Management Center Authentication

MindLink Anywhere Single Sign-On supports both Windows Integrated Authentication and NTLM mechanisms.

Windows Integrated Auth is supported in all browsers except for Safari. If Kerberos is not available, Single Sign-On automatically resorts to NTLM.

For Kerberos to be supported, the MLA URL must be registered as a Service Principal Name.

These are windows authentication mechanisms to authenticate using SSO. SSO (Single Sign-on) allows users to sign in once with their details and be automatically authenticated each time they visit the MindLink site.

NTLM: For the SSO functionality of MindLink Anywhere to work correctly, the MindLink Address will need to be treated as a trusted site section of the End-Users Web Browser. This can be configured by Group Policy or manually. These Instructions are based on Manual configuration using Internet Explorer - other Browsers may vary.

From within Internet Explorer go to Tools > Internet Options

Kerberos: operates using "principles" which are identifiers for users and services for which Kerberos tickets can be generated. So that a client can create a ticket readable by a service, it looks up the service principal name and asks the Kerberos server to produce a ticket that can be given to the service. If the service has no registered principal name, or an incorrect principal name is used (for instance falling back to a default service name) then the ticket will be incorrect and authentication will fail.

Windows Authentication: Windows authentication can be implemented by running the following command as a domain administrator:

setspn -U -A http://<server_fqdn> <server_fqdn>


setspn -U -A

Note this only affects Windows Authentication, NTLM does not use SPNs.

Bypass SSO By appending a query string to the URL the SSO mechanism can be bypassed, allowing the client to automatically utilise the configured authentication mechanism to log on directly without prompting. Windows configuration needs to be configured to use the bypass feature. The query string to bypass SSO is below:

  • ?bypassLogOnConfiguration=true#/ The first request will require the user to enter credentials, even when using the bypass query string. Every login after the initial will login automatically.

HTTP header authentication

MLA Management Center Authentication

  • SfB deployments require the users full sip address. For example: sip:testuser@domain

This allows the client to be authenticated using a configured pre-authenticated header. Enabling this option allows HTTP headers to be passed to an external authentication module, for example a proxy server.

Example: User credentials can be read from the relevant attributes within the HTTP header of the user's security certificate. These attributes are then authenticated against an authentication module such as a proxy. Once authenticated successfully, a session is then established.

OpenID Connect authentication

MLA Management Center Authentication

This allows the user to be authenticated using an OpenID Connect identity provider.

Authority URL: Specify the URL where the OpenID connect identity provider is hosted.

Client ID: Specify the client or application ID of the registered MindLink application on the OpenID connect identity provider.

Identity claim type: Specify the name of the OpenID connect claim type that can be used to uniquely identity the user.

Identity Active Directory attribute: Specify the name of the Active Directory attribute which will match the value of the OpenID connect claim type.

OpenID Connect scopes: Specify the scopes of the request that will be made to the provider. The "openid" scope is required.

Example: The configured user claim is retrieved on successful authentication with the identity provider. The claim is checked against the configured AD domain with the given attribute to identify the user for authentication with MindLink. Once authenticated successfully, a session is then established.

This requires the MindLink application to be registered with the identity provider. The registered application must be configured with the following:

  • A redirect URI matching the web client path, i.e. https://FQDN:port/yourbasepath
  • Support the authorization code flow with PKCE
  • Support the "openid" and any other configured scopes.
  • Returns your claim type of choice in the ID token, within the configured scopes.
  • Support CORS. For AzureAD identity providers, the V2.0 endpoint must be specified.

Note that OpenID Connect authentication is not supported on Internet Explorer. The mechanism will not be available to Internet Explorer users even if it is enabled in the management center.


When using Microsoft Azure Entra (Azure AD) as an OIDC provider, make sure that you use the v2.0 endpoint for the authority URL. Also make sure to include the email scope if you are using email addresses to link user accounts.

External URL Redirection

MLA Management Center Authentication

External URL redirection allows the MLA client to redirect to a specified URL in the event of authentication failure or the user logging out.

Authentication failure redirect URL will redirect the user to the configured URL if they fail to authenticate.

Log out redirect URL will redirect the user to the configured URL when they log out. If a user is unable to authenticate i.e. enters the wrong credentials, it is possible to have them redirected to an external URL i.e.
