Configuring user managed mappings
In Fisheye and Crucible, Administrators can control whether users can use the Author Mapping setting to map their own Fisheye/Crucible usernames to repository committer accounts or not. By default, the setting allows users to set their own mappings.
If you wish to lock down the mappings for security or audit reasons, this setting lets you restrict all management of mappings to Fisheye/Crucible administrators only.
To do this, click Administration in the footer of the Fisheye/Crucible interface and then Authentication (under 'Security Settings') in the left navigation bar. You can set User Managed Mappings either On or Off. The setting is applied immediately.
