I have a user that was commiting to our Git repository using different email addresses / names but is a single person. In FishEye / Crucible, how do I tell the tool to treat such commits as if they were from a single user? (E.g., BitBucket has an alias feature for this.)
Each user can set up their own committer mappings. This can be done from the settings dialog: http://confluence.atlassian.com/display/FISHEYE/Changing+your+User+Profile#ChangingyourUserProfile-AuthorMappingTab
An admin can configure these for any user/committer from the User Mappings section in the administration console.
