Hi all I have been using samba 3.0.21 with openldap , and facing some problems. i have taken backup of the ldap daily in ldif file. unfortunately our UPS got down and my PDC got rebooted, as a result my ldap database got corrupted i believe, using ldif file with slapcat command, i restored the ldap database, but my windows clients had to rejoin again and all my user's passwords had to resetted. why is this happening, how can i preven this, Regards Niranjan
