Re: [Samba] Server GC/name.dom/dom is not registered with our KDC: Miscellaneous failure (see text): Server (GC/name/dom@DOM) unknown




Ah.. I had a "member break down" ..  

Out of the blue,.. Kerberos problem, but pretty simple to fix.

Check your spn of the ad server with :  
samba-tool spn list DC_HOSTNAME$

Check keytab 
klist -ke /var/lib/samba/private/secrets.keytab

Can you check this.
