RE: RE: Help! Red hat doesn't recognize any usernames!



They looked to be fine, permissions, etc. I diff'd them to another identical
machine, and they matched up. I thoroughly went through the logs, the PAM
system, and nothing was out of the ordinary.

First time in 17 years I've ever encountered this problem. But, I was able
to recover all data and rebuilt the machine, so all is well.

I chalk it up to a red hat bug.

Are you sure the /etc/pam .d/system-auth is fine

Hello,

Are you getting anything in your system logs?

/var/log

There may be some clues in those logs? Assuming you have a way to view
the logs.

Good luck

Are you still unable to login as root? Have you tried booting
directlyinto single user mode?

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

Subject: Help! Red hat doesn't recognize any usernames!

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?
