Although FishEye always maintains a list of users internally, you can have FishEye authenticate and authorise users against an external authentication source.
To set an external authentication source, click 'Users/Security' on the 'Admin Menu'.
Only one authentication can be set at one time. However, each repository can have the option as to whether to use the authentication or not.
To change authentications you will need to remove the settings that are already configured. Just click the 'Remove' link. You will then be presented with the option to add a different authentication.
FishEye currently supports:
Configuring External Authentication Sources
