[xwiki-users] CAS authenticator and groups

Hello, I wanted to know if it is possible to filter by groups with CAS authenticator. http://extensions.xwiki.org/xwiki/bin/view/Extension/Authenticator+Jasig+CAS I must maps groups with xwikiAllgroups? Are there a parameter like LDAP one? #-# Only members of the following group can authenticate. #-# The following kind of groups are supported: #-# * LDAP static groups (users/subgroups are listed statically in the group object) xwiki.authentication.ldap.user_group=xxxxxxx and BTW for ldap authentication what's "LDAP static groups (users/subgroups are listed statically in the group object)" meaning? If I add a LDAP member in my LDAP group, I must relauinch Tomcat for synchronsie xwiki group? Thxs.
