Hi, You can implement your own version of the com.xpn.xwiki.user.api.XWikiAuthService interface. There's already a LDAP impl existing (different from the XWiki default one), so you can look over that too as an example. Then, you must precise in the xwiki.cfg configuration file that you want to use your own class, with something like xwiki.authentication.authclass = com.mycompany.mypackage.MyXWikiAuthImpl Regards, Jerome.
