Yesterday I was unable to authenticate offline using my AD account.
Normally when I start disconnected, I see my AD account in the GDM greeter.
But for some reason it was gone and when trying to connect in terminal mode, the /var/log/messages said: “User not known to the underlying authentication module”
Now I’m back on the network and after manually typing the AD user account and logon I can again see my username in the GDM.
Can someone please answer the following winbindd questions.
- Where does GDM get the active user profiles to enumerate the greeter?
- Where does winbindd store the offline account information?
- How can I backup/restore this information so when it gets corrupted I can repair without connecting to the server?
Thank you in advance.
