I have adopted a Jenkins installation and am attempting to configure project-based matrix security using the Jenkins user database. I have a couple users that cannot sign up and add themselves. They are getting the message "User name is already taken"*, *even though there is no user directory for these users and they don't show up in the manage users screen. In addition, the user names in question show up on the people page but can't be deleted there either. I tried by clicking on the user name and appending "delete" to the URL. I get the "Are you sure about deleting the user from Jenkins?" message and click Yes, but it doesn't remove the user from the people page.
Is there some other "black-ops" way of removing this type of rogue user account? Something else I'm missing? I really need to remove them so that the users in question can sign up and have accounts. Thanks, -Phil
