openssh unix dev - Apr 2005 - openssh-3.6.1p2 server did not accept user connection.

Hi,

Whenever i boot the machine, the sshd started using rc script is not
accepting ssh connection from a normal user. However it connects as root
user and also connects as a user when the sshd is restarted. The error
message is
"fatal: PAM session setup failed[6]: Permission denied"

What would be the reason for this behaviour ?

I am using Linux-2.6.5-1.358 (Fedora Core release 2) and openssh version
(OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f ) which came
with the distribution. The debug out is given below.

Thanks

There was an issue with selinux and sshd.  See:
http://marc.theaimsgroup.com/?l=openssh-unix-dev&m=108608103318162

If booting with selinux disabled solves your problem then that's 
probably it.
