Hello,
 I would like to request for a project that adds Jasig CAS
 (
http://www.jasig.org/cas) authentication support to the XWiki. We
 started using XWiki in our organization and we are using a CAS
 authentication. So I developed CAS authentication module to the XWiki
 and I would like to share it on XWiki Contrib. I would like to request
 for GitHub access. My GitHub user name is pabro.
 Name: XWiki Authenticator CAS
 Description: XWiki authenticator based on Jasig CAS. It supports CAS 2.0
 and SAML 1.1 protocol. SAML protocol can be used for attributes and
 group membership synchronization.
