Hi all,

I'm new on the list and I've got a problem that archive, Google, and brain
searches have failed to rectify:

My server has existing "/etc/passwd" accounts with existing e-mail traffic.  
I've just added vpopmail to simplify future account administration since the 
server's usage is increasing.  I would like to continue to support system 
accounts in addition to vpopmail accounts, at least for awhile.  

I've attempted to use vchkpw to authenticate both system (/etc/passwd) accounts 
and virtual (vpopmail) accounts, as vchkpw's documentation suggests it will 
do.  Unfortunately, my system accounts can not authenticate via vchkpw as 
called by both IMAP and SMTP-AUTH services.  Virtual accounts authenticate 
correctly to both mechanisms.

I'm running Qmail-1.03 (Patches: badrcptto, Krzysztof Dabrowski's
smtp-auth); Vpopmail 5.2.2; Courier-IMAP 2.2.0 (using authvchkpw module);
all on a RedHat 8.0 system.

The obligatory 'run' script snippet:

        exec /usr/local/bin/softlimit -m 4000000 \
             tcpserver -v -H -R -l "$LOCAL" -x /etc/tcp.smtp.cdb \
                       -u $VPMUID -g $VPMGID 0 smtp \
             /var/qmail/bin/qmail-smtpd $LOCAL /home/vpopmail/bin/vchkpw \

(VPMUID and VPMGID are set to the vpopmail uid and vchkpw gid.  LOCAL is the 
FQDN of the server).

I've found that authentication via [EMAIL PROTECTED] passes/fails correctly
to both IMAP and SMTP.  Authentication via a 'systemusername' or 
'systemusername@' results in vpopmail logging a "user not found" message.
If I add the 'authpam' module into courier-imap's configuration, both system 
and virtual accounts will authenticate.  SMTP-AUTH still fails, of course.
I found info on google about making sure vchkpw is running with sufficient 
permissions to access /etc/shadow and believe I have that correctly

So, my question in a nutshell is: Does vchkpw really handle both system and 
virtual accounts, and if so, what might I be doing wrong to keep it from
working as advertised?

If you've even gotten this far, thanks for your time!
