[xwiki-users] about password and LDAP

Hello, I have some questions (today :-) ) - I wondered where is stored local users password?  More precisely in which table? I see that users are in xwikidoc table: http://platform.xwiki.org/xwiki/bin/view/DevGuide/DatabaseSchema (but not the password) Note, I don't want reinitialize password (I know how to do it with superuser) - If I use LDAP authentication, a copy of  user ldap password is stored in the database? - With ldap authentication, I filter members by ldap statics groups #-# Only members of the following group can authenticate. xwiki.authentication.ldap.user_group=dn=_agents_,xxxx,dc=fr _agents_ contain a static list of memberUID with name.surname I active log for ldap and I saw that for the first connexion by a ldap user, cache creation take 1mn Apparently xwiki try to retrieve the dn for each member of the static group for generate his cache (~5 queries by member) Of course, I increased xwiki.authentication.ldap.groupcache_expiration value Are there a way to refresh the ldap cache by cron or scheduled script?
