Commiter Name

Hello all,

i’m totaly fine with gitlab.
If i commit something, ye see at the projekt Dashboard:
1234567 commitmessage 3 minutes ago by REALNAME

In Eclipse i defined Author and Commiter to my USERNAME.
How can i change, that the Username is shown in the Commit-Messages, and not the Realname?

In the Gitlab from a friend it is like that.

Anyone an idea?
