Re: [Courier-imap] UID/GID Errors with 4.3.0
Brian, Going by Sam's reply, this seemed to be an intentional change in 4.3.0 for a sanity check. I've already fixed-up my system by making the login groups match the homedir groups for the affected user. I would still like to go through the exercise here for my own sanity, though. :-) Jan 12 16:35:08 krweb authdaemond: Authenticated: sysusername=roddie, sysuserid=null, sysgroupid=20, homedir=/home/roddie, address=roddie, fullname=Roddie Hasan, maildir=null, quota=null, options=null OK, next check for HAVE_INITGROUPS in numlib/config.h It's defined to 1. Could you explain that last bit? How exactly are you running imapd? The group-changing code will only be invoked if imapd is running initially as root, and is changing the account to settings returned by courier-authlib That's what I would have figured, too - I am simply typing imapd, (which is not suid/sgid). Example when login GID does not match Maildir GID: % id uid=1037(yawnto) gid=20(staff) groups=20(staff),1002(users) % ls -ald Maildir/ drwx-- 17 yawnto users 512 Nov 5 12:17 Maildir/ % imapd * BYE [ALERT] Fatal error: Account's mailbox directory is not owned by the correct uid or gid: No such file or directory When the above GIDs do match (ie. I put yawnto back into users): % imapd * PREAUTH Ready. INFO: LOGIN, user=yawnto, ip=[127.0.0.1], port=[0], protocol=IMAP Regards, Roddie - This SF.net email is sponsored by: Microsoft Defy all challenges.

That's what confused me - firstly you showed courier-authlib logs showing the account being authenticated, but then you said that you're running imapd directly from the command line (which doesn't perform any authentication at all, nor change user or groups, so this is a red herring) Example when login GID does not match Maildir GID: % id uid=1037(yawnto) gid=20(staff) groups=20(staff),1002(users) % ls -ald Maildir/ drwx-- 17 yawnto users 512 Nov 5 12:17 Maildir/ % imapd * BYE [ALERT] Fatal error: Account's mailbox directory is not owned by the correct uid or gid: No such file or directory OK, I see there's an explicit check for this in imap/imapd.c: if ( buf.st_uid != geteuid() || buf.st_gid != getegid()) write_error_exit(Account's mailbox directory is not owned by the correct uid or gid); I've also seen Sam's reply. I can see where he's coming from - if you're going to use supplementary groups then you need to know what you're doing (e.g. use the sticky bit to ensure that the files created inside are owned by the directory's own group, rather than the user's primary group) But for other users, this whole gid check is superfluous: e.g. mode 700 is perfectly legitimate and often appropriate for a Maildir, in which case it doesn't matter what group is assigned. As Sam says - you can always kill the check. Regards, Brian. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Somebody modified Courier's startup script, or replaced Courier's startup script with some ancient monstrosity they found somewhere else on the Net, which was for an older version of Courier and does not work with the current version, or there was a problem upgrading Courier. Reinstall Courier, following the instructions in INSTALL. pgpgrJOsQ0Qeu.pgp Description: PGP signature - This SF.net email is sponsored by: Microsoft Defy all challenges.

Forgot to mention that I am on a gentoo system and use portage ebuilds to install. I did reinstall with portage with no luck.
