Gitlab CE password synchronized with CAS 3

Hi all,

I've configured Gitlab CE with OmniAuth and a CAS server (Single sign on) that authenticates against two Active Directories. The login process is working fine with the auto_create option to make the automatic signup, etc... but the authentication isn't working when usin git clients(git, sourcetree, gitkraken, etc).

Now i am sending a form data from the cas authentication with the user and password, is there any way i can update the user in the db with this data i am sending or to autmatically synchronize the password on a login?

Thank you in advance!
