User Settings Are Not Displayed in ADUC

If there is no group in a cell that can serve as the user's primary GID, for instance, because the default primary group, domain users, has been removed from the cell, the AD Bridge Cell Settings tab for a user in Active Directory Users and Computers (ADUC) will not display the user or group settings, as shown in the screen shot below.

To display the settings, enable a group that the user is a member of.
