forcing a user@ into the URL if not present

Hello,

I'm using git 2.3.2 with Kerberos for authentication and gito-lite for authorization.

This works:

$ git clone https://dvl@ repo.example.org/git/testing Cloning into 'testing'... warning: You appear to have cloned an empty repository. Checking connectivity... done.

My goal: have it work without supplying dvl@ as shown here:

$ git clone https://repo.example.org/git/testing Cloning into 'testing'... Username for 'https://repo.example.org':

I don't want to be prompted for a password.  I want Kerberos to kick in.

Following http://git-scm.com/docs/gitcredentials, the following seems to have nil effect. Anyone used this feature already?

  git config --global credential.https://repo.example.org.username dvl

$ cat ~/.gitconfig [credential "https://repo.example.org"] username = dvl [http] sslCAInfo = /usr/local/etc/trusted-certificates.pem

With the above, I still get prompted for a password

Given my use of Kerberos for authorization, is this option feasible?

Should I be taking a different approach?

Thank you.
