Hi ,
I've gotten Courier Imap to run pretty well, but I have spent the last
48 hours trying everything to get a simple scenario working with shared
folders. I would like to have a Software folder ( for the software team
) with access to only about 4 people. Each user should have read/ write
privileges without the ability to delete each other's emails. Seems
simple enough.
So I did the following on a Ubuntu 11.10 system , running these
packages ( output of dpkg -l |grep courier )
courier-authdaemon 0.63.0-3.1ubuntu1 Courier
authentication daemon
courier-authlib 0.63.0-3.1ubuntu1 Courier
authentication library
courier-authlib-ldap 0.63.0-3.1ubuntu1 LDAP
support for the Courier authentication library
courier-authlib-userdb 0.63.0-3.1ubuntu1 userdb
support for the Courier authentication library
courier-base 0.66.1-1ubuntu3 Courier mail server
- base system
courier-imap 4.9.1-1ubuntu3 Courier mail server
- IMAP server
courier-imap-ssl 4.9.1-1ubuntu3 Courier mail
server - IMAP over SSL
courier-maildrop 0.66.1-1ubuntu3 Courier mail
server - mail delivery agent
courier-ssl 0.66.1-1ubuntu3 Courier mail server
- SSL/TLS Support
courier-webadmin 0.66.1-1ubuntu3 Courier mail
server - web-based administration frontend
1. I created a system user *software* as follows
sudo useradd -r software
This created the system user and group for software.
2. I added my user and 3 others to the /etc/group entry for software,
logged out and logged back in again to prove they took.
3. Next I ran these commands in a shared directory as the user
*software* ( note the Shared directory already existed and was readable
from imap clients )
maildirmake -s write,group -f "Test" /var/mail/shared/Shared
This created the directory Test with the following permissions
drwxrwx--T 5 software software 4096 May 30 10:40 .Test/
4. I change the permission so that group can write to Test
chmod -R g+w /var/mail/shared/Shared/.Test/
5. Now I add the link in my Maildir
maildirmake --add Test=/var/mail/shared/Shared/.Test $MAILDIR
6. I next restarted courier imap, and the auth daemon
Now I am unable to see the Test directory inside of Thunderbird when I
go to Subscribe.
Questions:
1. Why is this the case
2. Secondly, do I even have to make this a system group. Why isn't this
just a regular Unix group ? If this is required, it might be beneficial
to actually include a step in the instructions showing users the desired
way to create this.
Currently, I can only make this work if I make the entire directory
world read-writable which isn't the desired behavior.
Thanks for any help on this matter,
Sincerely
-Jimi
