chase_referrals and rebind in 2.1.6

I am having some problems with an AD and FreeRADIUS. rlm_ldap debug lets me assume that there might be a relation to chase_referrals and rebind. According to the Changelog there have been changes regarding this in 2.1.6: Added "chase_referrals" and "rebind" configuration to rlm_ldap. This helps with Active Directory. See raddb/modules/ldap Unfortunately I do not find anything about it in that file. ~/freeradius-server-2.1.6$ grep -r -l -i chase_ref * debian/changelog doc/ChangeLog src/modules/rlm_ldap/rlm_ldap.c Similar result for rebind. What options might be configured for chase_referrals and rebind? Norbert Wegener
