        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: sshd
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: karthik.rangasamy at wipro.com


Hi 

We have around 480 users configured in one Linux(Suse 10) machine.
and the client program(ssh-client) makes ssh connection to the machine
for all the user at one stretch every 15 minutes.

but sometimes it throws the below error in the
syslog(/var/log/messages/) for some users:
Invalid user user1 from w.x.y.z

the error does not occur everytime. sometime it happens for user1...and
next time it works ok..

also the error occurs only in Suse10(openssh-4.2p1-18.38.3).This error
is not occuring in Suse 9(openssh-4.1p1-11.44).

we tried with different ssh clients but error happens with both the
clients..
Can you please let us know the reason for this error?
Is it a Bug or something related to configuration.

Thanks and Regards
Karthik

Can you reproduce the problem with the latest version (5.3p1) from
openssh.com compiled from source?

Are you using /etc/passwd as your user database, or something else
(NIS, LDAP, etc.)?

Please reopen if you can reproduce with a version that's a) recent and
b) not modified by a vendor.  If you want to stick with the version
provided by SuSE then you'll need to seek help from them.
