Re: [Samba] ERROR: Initialization failed for alloc backend tdb, deferred!




 Hi,
I tired to add second AD domain to provide access to my samba share from
RHEL5u3 server. Share access is working for primary domain and still users
from second domain doesn't have access to shares. wbinfo -u shows user
details from both domain. I could see below errors popped up in logs.
Updated krb5.conf with both domians realms. do we need to update any
additional steps in smb.conf for second domain?
