Please, re-open this and fix it!
In the Manage Jenkins/Configure System there should be a whole section for authentication. There's so many goodie links which aren't properly linked in the web interface. There's also no way for one to edit their Oracle credentials for downloading SDK-s. I think there should be a detailed section for the different types of credentials.
Clearly, you can delete the credentials in the respective XML files, but why have to do it manually...?
Apart from this, I somewhat don't agree with the idea of adding the links in the help section. Help and docs are great, but – why have to Google around or read the help when things could be more intuitive? The web interface has become fantastic over the last 10-15 builds. Very quick and responsive. Rather intuitive. This would make things even smoother.
