Dear all:

I have a weird problem. It goes like this:

I have about 200 users in eDirectory who are all linux enabled. They
could login OES linux via ssh to up until yesterday.

I did

# namuserlist -x ou=rd,o=company rd05

and the result is:

rd05:x:1001:604::/home/rd05:/bin/bash

which I assume that it shows the user exists.

But when I

# su - rd05

the system tells me:

su: user pm13 does not exist

And I check /var/log/messages, the following appears:

Feb 1 16:09:47 server01 sshd[10241]: Invalid user rd05 from 10.0.0.1

Any hint is appreciated, thanks.
