Hi Nunni, org.acegisecurity.BadCredentialsException: Bad credentials tells you at least that something is happening and then fails. This looks more like a matter of human engineering rather the technical engineering ;) Do you use some funny special character which may interfere with your system/shell/CLI. You will then have to escape the characters in question or evene better select a passwort less prone to error.
@David: "By the way, what are you doing with the command line? Jenkins is a purely web-based application, and the configuration is carried out via the webpage." ??? How did tell you that? The web based part is just a convenience thingy. You can run it from command line without webfront. I do more and more rarely use the webfront and run the administrative task straight from the operating systems CLI Further does Jenkins also provide it's own CLI (see: http://jenkins_server/cli) Take care Jan
