I recently upgraded PAM and OpenSSH to versions pam-0.77 and
openssh-3.8.1_p1-r1. My pam config for sshd accidentally got erased in
the process. ssh works fine, but I cannot scp. With scp -v I get the
following after entering the password:

Password:

My auth log led me to believe it was a problem with pam. When I use
'UsePAM no' in sshd_config, scp works fine. Contents of
/var/log/auth.log and /etc/pam.d/sshd follows.

/var/log/auth.log:

Aug 1 11:59:13 dpix sshd(pam_unix)[8182]: session opened for user dpix
by (uid=0)
Aug 1 11:59:13 dpix sshd[8182]: fatal: PAM: pam_open_session():
Permission denied

/etc/pam.d/sshd:

What am I missing in my pam config file for sshd? Or is it something else?

Thanks in advance,
Dan
