I installed gitolite and every thing works fine for me as admin. But when I'd like to add add a new user the new user can't connect to the server. After I looked into the file authorized_keys I saw that the new user wasn't added to the file. During the commit of the new public-key I get some workings:

How can I fix it that gitolite auto-add the new user to the authorized_keys.
