Hi sagay_d sorry but I'm testing the plugin with a clean jenkins installation and I can't find any section in the jenkins configuration or credentials where appears something like "Access Control Security Realm" or "Active Directory". I guess that is because you have some additional plugins installed.
I will set this issue as resolved as the basic credential management is supported and already merged to be released in the next plugin version. So I'd wait until the next release, test it again with the new plugin version and in case the problem is still persisting please create a new issue and provide more information about your setup like jenkins version, plugins involved...
Thank you very much for your colaboration 
Looks like there is an existing plugin that may help: https://wiki.jenkins-ci.org/display/JENKINS/OAuth+Credentials
