I'm having a problem with the Server app on my Mac Mini.
I had to renew my Domain Name and DNS is now working well. But i can not edit existing user accounts or add new user accounts to my Server. The the + and - buttons to add or remove users are greyed out and it is not possible for me to edit something under this Service. And under the Server app it is not possible to add a Network user.
What might be causing this problem?
