Description: Slow ssh authentication on Debian systems.

Affects: 

Summary: SSH commands function, but are slow to connect on Debian clusters.

Symptoms: SSH transactions are slow to authenticate and connect.

There is an issue with PAM support in OpenSSH version 3.9p1 packaged with some versions of Debian that causes a short delay during ssh authentication. To remove the delay, set the 

UsePAM no

option in /etc/ssh/sshd_config.
