While upgrading to syslog-ng to version 3.13.2 I suddenly ran into an error that prevented the daemon to start. The error message was: Wed, 08 Aug 2018 21:00:00 +0000 https://www.guido-flohr.net/syslog-ng-unique-persist-names/index.html https://www.guido-flohr.net/syslog-ng-unique-persist-names/index.html Syslog-ng Linux System Administration <img src="/assets/images/simple-single-sign-on/sso.svg" width="100%">Individual user and password databases for every single service in a network are a nuisance for users and for admins, especially when users have a tendency of forgotting their password.

Setting it up will pay out in little time.
