Cannot change NIS passwords in Squirrelmail
 

Hi all!
I have the following setup on my Fedora Core 1 Box:
-MTA - Sendmail
-IMAP - wu-imap
-Webmail Client - Squirrelmail

Well, everything's normal, i can log on to squirrelmail using NIS username & password.
But there's a problem whien i want to change passwords.
I have the change_password plugin installed for PAM which uses poppassd. I also have my poppassd running.

When i log in (authentication is ok from NIS server) and try to change passwords:
There's an error:

--> RPC: Can't encode arguments500 Server error, password not changed

my /var/log/messages say :
Mar 23 10:25:02 sshserver passwd(pam_unix)[27172]: password not changed for user1 on test-sfu

where ... sshserver is my mail server, test-sfu is my NIS server and user1 is the user logged on.

Is it NIS problem or IMAP or poppassd or PAM ? I cannot figure out.
Since error says RPC: ... i think it is NIS problem.

Can anyone please enlighten me on this ?
Please help.
Thanks and regards

Well, now I located where the problem is :
Problem is in poppassd.
I tried to telnet my server on port 106 and tried to change password.
It outputs the same error.

But how to fix this ?
