Thanks for the review Andreas. Since it sounds like the test case is
invalid, this SRU attempt will have to be abandoned. I'll return this
to the backlog for the reporter to re-clarify reproduction steps, for
re-assessment in triage.
@Rene please see Andreas' feedback.

Title:
saslauthd wrong permission of /var/spool/postfix/var/run/saslauthd
Status in cyrus-sasl2 package in Ubuntu:
Fix Released
Status in cyrus-sasl2 source package in Noble:
Incomplete
Status in cyrus-sasl2 source package in Oracular:
Fix Released
Bug description:
[Impact]
Incorrect ownership of files in saslauthd's run directory can result in
service issues (e.g. failure to authenticate, failure to restart, etc.)
saslauthd itself will appear to start successfully, but e.g. postfix will be
unable to authenticate, effectively preventing outgoing mail submitted via
smtp. This worked properly on prior LTS releases, but breaks outgoing mail
service on upgrade to 24.04.
[Workaround]
# 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.
[Test Case]
$ sudo apt-get install postfix sasl2-bin
$ sudo systemctl enable saslauthd
$ ls -ld /run/saslauthd/
drwx--x--- 2 root sasl 40 Sep 24 23:07 /run/saslauthd/
$ sudo systemctl start saslauthd
$ ls -ld /run/saslauthd/
drwxr-xr-x 2 root root 140 Sep 24 23:09 /run/saslauthd
[Where Problems Could Occur]
Since the fix is only in packaging and deals only with group ownership,
regressions would be expected to be limited to permission issues relating to
packaging files (configuration, daemons, logs, etc.)
Notably, the fix corrects group ownership permissions on the
*directory* itself, but not on its contents. The service itself
continues to run as the same user, so it should not cause any
read/write problems, but if there are any issues pertaining to *group*
ownership, those may be relate to this change.
[Original Report]
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
