* When cups has set the "SystemGroup" directive to an external group provided through sss and cups starts before sssd has finished booting, cups will crash because the group does not exist. * The patch adds an "After=sssd.service" clause to the service unit file. [Test Case] * Configure an external authentication service (LDAP, AD...) and create a group, for instance "[email protected]" * Set SystemGroup to match that group in /etc/cups/cups-files.conf: SystemGroup [email protected] * Reboot * If cups has started before sssd has finished booting, cups will crash: Mar 27 10:10:33 cups-sssd cupsd[21463]: Unknown SystemGroup "[email protected]" on line 19 of /etc/cups/cups-files.conf. * If cups starts after sssd, it will work fine. [Regression Potential] * Minimal: this patch affects just the ordering of the service unit file. [Other Info] * Upstream: https://github.com/apple/cups/commit/4d0f1959a3f46973caec2cd41828c59674fe195d [Original description] When cups has set the "SystemGroup" directive to an external group provided through sss and cups starts before sssd has finished booting, cups will crash because the group does not exist. For instance, with a group named [email protected] served from Active Directory through sssd, if the sssd service hasn't booted before cups: Mar 27 10:10:33 cups-sssd systemd[1]: Started CUPS Scheduler.
