I do not want new users to be able to sign up. So in Jenkin\'s Configuration, I disabled \"Allow users to sign up\" with using Jenkin\'s own user database.
But how c
In case "Allow users to sign up" was already disabled and security turned on and there is no user you can use to login the only way to go is to change Jenkins configuration manually on the server and restart server.
Thing to change is in Jenkins Home folder i config.xml file. change
true
to
false
restart and refresh browser
Voila!!!
