Hello,

I recently installed dovecot1.0rc25 on my RHEL4 system running postfix and wish to use both virtual and system users. Virtuals work fine, but I get authentication failures with system users. I've tried pam, passwd and shadow.

Attempting to telnet as system user
telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
* OK Dovecot ready.
a login user passwd
a NO Authentication failed.

and corresponding log

Below is the output of dovecot -n
