I have consulted with a couple of colleagues. We believe we may know what the problem is, but I would like for you to confirm.
To recap: I look in Consumers - Users on the Universal Server and only see first names.
From what I've learned is that the data I'm looking for is predefined in the LDAP directory. For example, in your screenshot, your full name is based on the cn or displayName attributes. If this is correct, the problem is that our LDAP directory only shows the first name. Is there a way within the Universal Server to show more of the columns that may list the last name (whatever that attribute may be on our LDAP directory)? Would the issue only be resolved by changing our LDAP directory?
Thanks for your continued patience. Hopefully this will prove to be a valuable resource for others.
