proxy request when database is referering to ldap server

Hi All, Im trying to authenticate a user@realm.com The same realm is found in the realm list & the request got proxyed. But the freeradius server is still trying to do ldap_groupcmp(). When 2-3 ldap servers are configured the radius server is busy in connecting to those.. & fails in case of non-reachable condition. Mean while the server says: Reply from home server x.y.z.a:1812 - ID: 0 arrived too late for request 0. Try increasing 'retry_delay' or 'max_request_time' Waking up in 5 seconds... Do anyone have an idea of why is it trying to do ldap_grpcmp() during proxy state?? Please let me know if you have any idea. Thanks Sumi
