SYMPTOMS
Network Information Service (NIS) servers may not authenticate UNIX users with their group permissions.



CAUSE
When a UNIX user is added to a UNIX group by using Active Directory, the NIS server updates the group.byname and group.byuid files in its MapCache folder to be the same. These files are used for group authentication. When NIS updates these files, it uses the user's CN name rather than the MsSFUName attribute. This can result in an invalid user ID being added to the group files if these are different.

For example, a user with a CN name of &quot;First Last&quot; and a logon name of &quot;firstlas&quot; would have the invalid &quot;First Last&quot; name added to the group files.
