Jenkins CI – Authentication Lockout

Jenkins CI – Authentication Lockout

By : -

As I’ve been working with Jenkins lately, authentication has become an obstacle to overcome. I’ve begun using the AD plugin for authentication which seems to work fairly well. Two issues that I have found semi regularly as I test and implement solutions around authentication are; 1) administrator locked out, and 2) connection timeouts to AD from Jenkins.

In order to resolve the issue with any user getting locked out, there are two possible solutions that I use. The one that seems most recommended on the internet is to edit the config.xml in the Jenkins home directory and set useSecurity to false. I don’t like this and don’t use it anymore. The method that I prefer (when locking myself out) is to set myself up as the administrator by adding the following permission node:

hudson.model.Hudson.Administer:USERNAME

After that, a restart of tomcat will allow you to login as the administrator.

As far as the connection timeouts, those are intermittent and have not yet warranted detailed troubleshooting. I am using an uncommon network configuration for this particular deployment which introduces quite a bit of latency at times.
