I had the same problem that's why I got back to my 1.7 version of Courier which works fine for me.

To test your theory, try vpopmail 5.4.0. I know that Michael Bowe
worked on the vpopmail code in courier-imap, so I don't see any reason
for the latest builds to not work.
Yes earlier this year I rewrote the vchkpw code that is included in
courier-imap. The idea here was to fix some broken functionality and to also
close some security issues. My changes were included in the v3.0.0 release
of courier-imap.
I use vchkpw 5.4.x and courier-imap-3.0.x on my production server and
haven't seen the problem you describe. To make sure something hadn't slipped
by, I just updated my server to the latest (5.4.7+3.0.8) and ran it in a few
different combinations eg with/without roaming users, with/without
authdaemon.. Still couldn't duplicate your problem.
I know where in the code your problem is occurring. vchkpw authentication is
handed in the courier-imap source primarily by authlib/authvchkpw.c. In this
file, once a user has been successfully auth'ed, courier-imap executes this
function :
authsuccess(a-homedir, 0, a-sysuserid, a-sysgroupid, a-address,
a-fullname);
authsuccess() switches to the supplied user/group and then does this :
if (chdir(homedir))
{
fprintf(stderr, chdir \%s\: %s\n, homedir,
strerror(errno));
authexit(1);
}
So, for some reason your homedir field just contains username rather than
the full path to the user's dir.
To try and get to the bottom of this, I would suggest that you edit your
imapd file (/usr/local/courier-imap/etc/imapd or similar), and set
DEBUG_LOGIN=2. Then restart your courier-imap daemon. Then look in your
/var/log/maillog. This is an example of an entry from my logs :
Sep 26 22:25:30 reef imapd: authvchkpw:
[EMAIL PROTECTED],
sysuserid=89, sysgroupid=89,
homedir=/home/vpopmail/domains/1/pipeline.com.au/X/mbowe,
[EMAIL PROTECTED], fullname=Michael Bowe,
maildir=null, quota=null, options=null
Note how the homedir contains the full path to the user dir.
And the corresponding vuserinfo shows :
[EMAIL PROTECTED] etc]# vuserinfo [EMAIL PROTECTED]
name: mbowe
passwd:
clear passwd:
uid:0
gid:0
flags: 0
gecos: Michael Bowe
limits: No user limits set.
dir: /home/vpopmail/domains/1/pipeline.com.au/X/mbowe
quota: 524288000S
usage: 14%
last auth: Sun Sep 26 22:25:30 2004
last auth ip: imap
Again, you can see how the full path to the user dir is displayed.
Jeremy, how does this compare with your system?
Michael.

Seems as if Sam was serious about any problems regarding vpopmail authentication being ignored on the Courier IMAP list :-/ Even though I'm not convinced it's a vchkpw problem, I'm forwarding here; sorry for the double post for those subscribed to both lists.. Please note i've upgraded gcc to 3.3.2, make to 3.8.0, and gdbm to 1.8.3. I'm running qmail 1.03 (with a bunch of patches) and vpopmail 5.4.6 on solaris sparc 2.7. using gcc 3.2.1. I had courier-imap 1.7.0 installed and working perfectly. for some reason, i decided i should upgrade. I downloaded, compiled, and installed 3.0.8. the new imap server closes the TCP connection immediately after my client sends login information. my logs show: INFO: Connection, ip=[127.0.0.1] LOGIN: DEBUG: ip=[127.0.0.1], command=LOGIN LOGIN: DEBUG: ip=[127.0.0.1], [EMAIL PROTECTED] chdir foobaz: No such file or directory i've configured with: CPPFLAGS=-I/usr/local/ssl/include -I/home/vpopmail/include \ LDFLAGS=-L/usr/local/ssl/lib -L/home/vpopmail/lib \ CC=gcc ./configure \ --prefix=/usr/local/courier-imap \ --enable-workarounds-for-imap-client-bugs \ --without-ipv6 --without-userdb \ --with-syslog=MAIL --without-authpwd \ --without-authshadow --without-authpam \ --without-authuserdb --without-authcram \ --with-authvchkpw --without-authldap \ --without-authmysql --without-authpgsql \ --without-authdaemon --without-authcustom i've tried using different email addresses, i've tried using %s instead of @s (and variations thereof). I've googled for hours (too much noise about chdir Maildir getting in the way). I've even tried installing 2.2.1 and 1.7.3. each of them is exhibiting the same behavior. i dont believe this problem is of vpopmail, as qmail-popup is authenticating against vchkpw, and i can test vchkpw: goofy# printf %s\0%s\0%s\0 [EMAIL PROTECTED] asdf ABC123 | vchkpw pwd 30 /home/goofy/vpopmail/domains/jeremykister.com/foobaz I've clearly botched something, but since I did this overnight, and it's turn into a sleepless night, I just cant figure out what's wrong. Any Ideas? Jeremy Kister http://jeremy.kister.net/
