We are having a problem getting a NetApp filer to re-join a samba domain after a move to a new network. The filer worked fine with samba before the move. Apologies in advance for the long missive. I've tried the following: - re-running the CIFS setup program on the filer - removing the problem filer's samba account, replacing it, and re-running the setup program on the filer

I'm newbies in SAMBA and NetApp filer , I use Filer with OpenLDAP as an authentication and authorization server , but look like NetApp doesn't work properly ( can't authentication ) , NetApp engineer suggest me that NetApp work properly with pure ActiveDirectory Environment. not SAMBA + OpenLDAP backend like me have. so I solve this problem by make Samba as native PDC and use

The filer is in the domain and uses ldap to map user ids and that seems to work. Samba maps the

I was searching tonight how to update OLD systems. I have C5 and C6 systems that need updating and they are remote systems. I followed the paths and ended up at DNF. Is this a valid option for updating C5 and C6 to take them to C7? Thanks, Jerry
