Chapter 8 Managing Users and Identity Stores

Managing External Identity Stores

 

The External User Groups dialog box appears displaying a list of AD groups in the domain, as well as

 

other trusted domains in the same forest.

 

If you have more groups that are not displayed, use the search filter to refine your search and click Go.

Step 3

Enter the AD groups or select them from the list, then click OK.

 

To remove an AD group from the list, click an AD group, then click Deselect.

Step 4

Click:

Save Changes to save the configuration.

Discard Changes to discard all changes.

Note

Note

If AD is already configured and you want to delete it, click Clear Configuration after you verify that there are no policy rules that use custom conditions based on the AD dictionary.

It is not recommended to use domain local groups in ACS policies. The reason is that the membership evaluation in domain local groups can be time consuming. So, by default, the domain local groups are not evaluated. Therefore, if you install patch 3 or later, ACS 5.3 does not retrieve domain local groups.

When configuring the AD Identity Store on ACS 5.x, the security groups defined on Active Directory are enumerated and can be used, but distribution groups are not shown. Active Directory Distribution groups are not security-enabled and can only be used with e-mail applications to send e-mail to collections of users. Please refer to Microsoft documentation for more information on distribution groups.

Note Logon authentication may fail on Active Directory when ACS tries to authenticate Users who belong to more than 1015 groups in external identity stores. This is due to the Local Security Authentication (LSA) limitations in Active Directory.

Configuring AD Attributes

Step 1 Select Users and Identity Stores > External Identity Stores > Active Directory, then click the Directory Attributes tab.
