saslauthd wrong permission of /var/spool/postfix/var/run/saslauthd

[Rene Schickbauer]

Folder group permission of /var/spool/postfix/var/run/saslauthd gets reset to "root" (should be "sasl") every time saslauthd gets restarted.

This worked fine before upgrading from 22.04 to 24.04

My automated workaround currently is this crontab (root) entry:

*/1 * * * * /usr/bin/chgrp sasl /var/spool/postfix/var/run/saslauthd 2>&1

Hi Rene,

Thank you for filing a bug.

Indeed, I can confirm that the problem exists. It's caused by the fact that Noble's saslauthd ships a systemd unit now, and that unit is not setting the "Group" parameter for the service.

Your workaround is OK, but if you want a better one, you can do the following (as root):

# systemctl edit saslauthd.service

Then, put the following lines inside the file:

[Service]
Group=sasl

Save the file, and restart the service. You should now see the right permissions/owner/group under /run/saslauthd.

I'm going to mark this bug as Triaged.

Thanks.
