Hi, I had the same problem this morning. In addition to the last message I can add this for diagnosis:
root@it-linux:~# smbclient -L ldap-dc1 -Ufz Enter fz's password: Domain=[OHM] OS=[Unix] Server=[Samba 3.6.6] Sharename Type Comment --------- ---- ------- netlogon Disk Network Logon Service IPC$ IPC IPC Service (ldap-dc1 server) fz Disk Home Directories Domain=[OHM] OS=[Unix] Server=[Samba 3.6.6] Server Comment --------- ------- LDAP-DC1 ldap-dc1 server Workgroup Master --------- ------- OHM LDAP-DC1 root@it-linux:~# smbclient -L it-data -Ufz Enter fz's password: session setup failed: NT_STATUS_TRUSTED_RELATIONSHIP_FAILURE Contacting the DC directly works fine but contacting a member server doesn't work. I also tried to remove the client from the domain and join it again, but that also didn't help. My temporary solution was to downgrade to the previous version samba/2:3.6.6-6+deb7u7 (all related packages) and the system is running again fine.
