[xwiki-devs] Using a custom Authentication and Authorization provider with XWiki workspaces

Hi, I am a newbie to XWiki. I am trying to integrate XWiki with a our own Security database over JAAS. The goal is to manage the workspaces based on the credentials and groups that exist in our security store. I see XWiki supports LDAP but no mention of JAAS. Can you point me to where in the source code I should make the modifications to make it use my security provider? Any examples would greatly help. Thanks in advance. NS
