Using Sernet rpms means you should be checking with the Sernet folks. I believe the problem may be that Centos samba looks for the tdb files in /var/cache/samba while Sernet looks in /var/lib/samba.
Yeah Toby!
I checked in both .. / Var / lib / samba ... / Var / cache / samba ... I left the two with the same content ... but .. without success. I noticed the change after upgrade dirs smb.
I also changed the source rpms .. I went to Epel. repo! Also without success ... :( [] 's Camun
