SYMPTOMS
When you add a user to a group with the Active Directory Users and Computers snap-in may not work under the following conditions:
 * The user name includes a comma.
 * The domain controller that the snap-in is focused on is not a global catalog.
 * The user account is from a different domain than the domain controller.

The error message you receive is:

The specified user was not found. If the user exists on another domain controller in the enterprise, it may take 15 minutes or more for the user to be replicated to the global catalog.

Although the error message indicates that when you wait 15 minutes this issue will be corrected, it does not in this case.



CAUSE
Before the user is added, the name is compared to the version that is stored in the global catalog cache. Because of the restricted character, the comparison does not succeed.

In this example the user name is First Last; the user name is Flast. The display name is Last, First.

The LDAP version of the entry (the one the snap-in uses) is:

CN=Last\, First,CN=Users,DC=DOMAIN,DC=com

The entry it is compared to from the cache is:

CN=&quot;Last, First&quot;,CN=Users,DC=DOMAIN,DC=com

LDAP protects the comma with a backslash; the cache protects it with quotation marks.



RESOLUTION
To work around this issue, set the focus of the Users and Computers snap-in to a domain controller that functions as a global catalog server.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
