IMAP-Problem: directory is not owned by the correct uid or gid

[st2xo]

I have a problem with the correct uid and gid with Maildir-directories.

I set up a standard ISPConfig-2.2.25 on Suse11 with Maildir and changed the Userid- and Groupid-Range to both 8000 (ISPConfig Panel Administration/SystemConfig)
(because of more comfortable restore-possibilities with rsync)

All ist fine except the login with imap-mail client (I use Squirrel), this error occurs:

"ERROR: IMAP server closed the connection. Server responded:* BYE [ALERT] Fatal error: Account's mailbox directory is not owned by the correct uid or gid"

I checked now the uid/gid no /home/www/web2/user:

drwxr-xr-x 5 web2_info web2 4,0K 21. Okt 17:11 web2_info/
drwxr-xr-x 5 web2_webmaster web2 4,0K 2. Dez 13:05 web2_webmaster/

and in /etc/passwd

admispconfig:x:1003:1003:Administrator ISPConfig:/home/admispconfig:/bin/bash
ispconfigend:x:20000:20000::/home/ispconfigend:/sbin/nologin
web2_webmaster:x:8001:8002:webmaster:/home/www/web2:/bin/false
web2_info:x:8002:8002:info:/home/www/web2/user/web2_info:/bin/false

in /etc/group:

users:x:100:web2_info
admispconfig:x:1003:admispconfig
ispconfigend:!:20000:
web2:x:10002:admispconfig,web2_webmaster

My question - before I´m starting experiments with the uid/gid on the dirs and files - are that settings as above correct?
Why is the "web2_webmaster" not part of group "users"? Is that correct?
Is there - or could be - any problem by change die uid/gid-ranges (8000 in my example)

Thanks for any hints or help!

(I found this thread t=27618 and have tried the recommended, but no result)

What's the output of

ls -la /Maildir

in the home directory of one of the affected users?

[st2xo]

Hi Falko,

/home/www/web2/user/web2_info

drwxr-xr-x 5 web2_info web2 4,0K 21. Okt 17:11 ./
drwxr-xr-x 12 web2_webmaster web2 4,0K 23. Sep 13:33 ../
drwx------ 7 web2_info web2 4,0K 21. Okt 17:00 Maildir/
drwxrwxr-x 2 web2_info web2 4,0K 23. Sep 12:42 web/


/home/www/web2/user/web2_info/Maildir:

drwx------ 7 web2_info web2 4,0K 21. Okt 17:00 ./
drwxr-xr-x 5 web2_info web2 4,0K 21. Okt 17:11 ../
drwx------ 2 web2_info web2 4,0K 5. Dez 07:27 cur/
drwx------ 2 web2_info web2 4,0K 5. Dez 09:49 new/
drwx------ 2 web2_info web2 4,0K 5. Dez 09:49 tmp/

(all the hidden files are not in the list)

I already have done chmod 775 on the dirs which are 700 above.
But no effect, same imap error.

Meanwhile I have added the users (web2_webmaster, web_info) to the groups "users" and "web2" - no effect, same error

Which IMAP server do you use?

[st2xo]

courier-imap 4.3.1-18.1,
(installed with ISPConfig-2.2.25, perfect Suse11 Setup)

I checked the logging in /var/log/mail:

http-GET the Squirell-Webmail Interface
Dec 6 00:50:05 srv2 imapd: Connection, ip=[::ffff:127.0.0.1]
Dec 6 00:50:05 srv2 imapd: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=30, sent=452

http-POST the address/password-data:
Dec 6 00:50:24 srv2 imapd: Connection, ip=[::ffff:127.0.0.1]

results in the error "ERROR: IMAP server closed the connection. Server responded:* BYE [ALERT] Fatal error: Account's mailbox directory is not owned by the correct uid or gid"

that is very confusing to me:

"imapd Connection" und "Logout" with the http-GET and another "imapd Connection" with the http-POST? That looks very strange.

On another system (older versions, no imap-problem) there is a complete different behaviour in the /var/log/mail with GET the Squirell-Login Form and POST the data ...

Can you check if web2_info is maybe listed more than once in /etc/passwd?

[st2xo]

first: sorry for my late answers ...

both users are listed once in /etc/passwd:
web2_webmaster:x:8001:8002:webmaster:/home/www/web2:/bin/false
web2_info:x:8002:8002:info:/home/www/web2/user/web2_info:/bin/false

Then I'm running out of ideas...

[st2xo]

hope next week to be able to run some tests on this topic.
(oops - one week to xmas .... )

First I will "reset" the uid/gid values in
ISPConfig/Panel Administration/SystemConfig
to none values or ... ?
(is it possible to delete the values, so that the field will be empty?)

If somebody has any ideas, I would be glad for your comments!
Thanks so far!
