Github integration without OmniAuth

Is there a way to enable github integration for specific users without enabling omniauth? In my organization i truly do believe i would be thrown off the roof of our really big building for enabling any form of authentication other than LDAP (aka, omniauth is completely out of the question), but, there are maybe 1% - 2% of our users that we would like to give the ability to import projects from github and push merge requests back to github.

Is this possible? Planned?
