Hi Rajiv,

It's Red Hat Enterprise 4, and it's local Authentication. (No Ldap.) It's
bizarre, really.

After it crashed, it came up, but doesn't recognize any usernames at all. I
did a repair, and looked at the /etc/passwd file and it was fine. It seems
the system cannot read from the file. I checked permissions, reset them, on
that and the shadow file, and still, the system cannot recognize logons.

Is there a daemon that is used for this that may not be starting up?

Thanks

Anne

Hi All,

My server crashed. Now when I boot it up, just about all
services/daemons that depend on any username, won't start because it
doesn't recognize the username. I can also no longer logon as root or
any other username because Red Hat doesn't recognize that the "user
exists."

Does anyone have any ideas on how to troubleshoot or fix this very odd
issue? My entire server is down because of it, which means 450 people
can not logon to my network.

I've fixed the file system, and now it has no errors. The Haldaemon
won't start, nor the message bus, or atd, or many others.

Thank you for your help!

Anne


which authentication do you use? local password or ldap server?
what version of Redhat?
