User linking is used when you want to create a user account based on an existing user in your company's directory service, for example, Microsoft's Active Directory. With this method you add user accounts for one user at a time, according to your global user account settings, with links to the appropriate user storage location. The user storage must have been set up first. Linking can also be automatically done when a new user logs in to the system at the first time, depending on an authentication method.
Automatic linking When a user tries to access a resource using a Digital Access authentication method, and no matching Digital Access user account exists, a Digital Access user account is created and the user information is linked from the user storage location to the new user account.
If users are moved in or deleted from the user storage location, established links between Digital Access user accounts and your company's directory service will be broken. When this occurs, these users cannot be authenticated. To repair broken links, missing users are searched for in the user storage location and when found the link is re-established.
