Description of problem:
We installed the new imap package on our mail server. We run imap through a
secure tunnel. We found that users who had nis accounts could not
authenticat themselves to obtain their mail.  The only people who could
authenticate themselves were the system administrators who were allowed to
log in to the mail server. In the previous imap package, anyone who had a
valid nis account could log in to receive their mail.

How reproducible:
Always

Steps to Reproduce:
1. Install new imap
2.Start imap via stunnel on server.
3. Have nis running and make sure that not all account can log in to server
.
4. Start netscape and attempt to log in to download mail from server.
	

Actual Results:  Users with login priveleges to server are able to get
their mail. All other users fail to authenticate. (Pam messages appear in
the syslog)

Expected Results:  Everyone with a valid nis account should be able to log
in and get their mail.
