Openfire + Ldap synchronize group relationships

Hi:

I hava problem in synchronizing openfire users and ldap user. When I changed a user infomation in my ldap server, openfire changed immediatly. And if a group infomation has been changed, openfire responded soon. But if I changed user’s group, openfire has not any actions, until I reconfigure openfire.

Both OpenLdap and Active directory have same problem.

Is anyone here can help me?

best regards
