Setting passwords on LINUX servers failure - Agent Not Installed

I am running Linux Servers RHEL 5

For each server, there is a login user (pmpuser) and of course root.
I can verify both are pmpuser and root are in sync with no issues from the PMP WEB GUI.
When I try an SSH connection from the SSH tool , it works
In Linux, I can see the pmpuser logging into the server from /var/log/secure when verifying the passwords are in sync

The issue now is with changing the passwords. Regardless of the su or sudo setting the password change fails with the message below:

Activity logs :

Timed out

Trying to use Agent Mode :
1. Agent not installed in host00019

Has anyone encountered this? How is it possible that despite all the SSH working correctly that this portion is failing?

Thanks
