Community Support for OpenDocMan (Deprecated)

Hello .
Is it possible to use Open Source User Authentication & Management application for uses log in to OpenDocMan?
Can something like AuthManager <!-- m --><a class="postlink" href="http://www.stitchapps.com/products/auth-manager">http://www.stitchapps.com/products/auth-manager</a><!-- m -->
or The Janrain User Management Platform (JUMP) OpenID <!-- m --><a class="postlink" href="http://janrain.com/products/">http://janrain.com/products/</a><!-- m -->

be integrated to run with Open Doc ?
If yes , where to begin ?

You can create a plug-in to handle the authentication.
