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: XXXX
clear passwd: XXXX
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.
