Re: [PLUG] Disaster Recovery and user accounts

This could be caused by many...many things....ranging from permission
problems to the hostname not being consistant. What I would suggest is
to boot into single user, tail the syslog, and switch to a new tty to
attempt to log in and see what kinda of error your syslog prints. If
that doesn't work, try different logs that might be related. Good

I have a Red Hat Enterprise 3 Server that host my company Oracle DB and
we have started practicing our Disaster Recovery Procedures.  We do a
complete tape backup with the Oracle Db shutdown (cold backup)

When I restore our backup to our test machine which is identical to the
production machine I do all the mount points and directories with the
exception of /dev and /proc.

After the restore and reboot, I go to the console and try to logon as
root and I get the following message:

FAILED LOGIN 1 FROM (null) FOR root, Authentication service cannot
retrieve authentication

I made sure  that /etc/users /etc/groups /etc/passwd were all copied
from the tape.

Anybody know what to make of this error?  Should I not exclude those

I tried a single user boot for the server and changed the root password
but as soon as I log out and try to get back in I get the same errors.

Thanks in advance
