** Description changed: - Folder group permission of /var/spool/postfix/var/run/saslauthd gets - reset to "root" (should be "sasl") every time saslauthd gets restarted. + [Impact] + Incorrect ownership of files in saslauthd's run directory can result in service issues (e.g. failure to authenticate, failure to restart, etc.) + + [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 + 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 permissions, regressions would be expected to be limited to permission issues relating to packaging files (configuration, daemons, logs, etc.) + + Notably, the fix corrects permissions on the *directory* itself, but not + on its contents. Since the problem is that root ownership of the + directory prevents non-root users from adding non-root owned files + there, it is unlikely this situation would crop up in practice, and if + it did should be reviewed and analyzed by the user. (We would not want + to auto-fix unknown root-owned file permissions to non-root.) + + + [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 2>&1 ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: postfix 3.8.6-1build2 ProcVersionSignature: Ubuntu 6.8.0-41.41-generic 6.8.12 Uname: Linux 6.8.0-41-generic x86_64 NonfreeKernelModules: zfs ApportVersion: 2.28.1-0ubuntu3.1 Architecture: amd64 CasperMD5CheckResult: unknown Date: Tue Sep 3 19:52:59 2024 SourcePackage: postfix UpgradeStatus: Upgraded to noble on 2024-08-31 (3 days ago) mtime.conffile..etc.init.d.apport: 2024-07-22T16:59:07
