[Samba] lost passdb, workstations lost trust relation ship

[Nicolas Kowalski]

Hello,

After a catastrophic disk failure, I restored all the contents of 
/var/lib/samba of our Samba 3.0.11 PDC (debian 3.0).

However, when logging on any workstation, we keep having an error about 
a failed trust relationship. Here is a sample:

smbclient -L <workstation> -U kowalski
Password: 
session setup failed: NT_STATUS_TRUSTED_RELATIONSHIP_FAILURE


I must be missing a file to restore, but which one ?

Many thanks in advance.
