Folks, sorry for bringing this up again. I am running FreeRADIUS 1.1.4 and OpenLDAP 2.3.32 on two Solaris10/x86 hosts. Non-redundant config works fine with FreeRADIUS and OpenLDAP on a single host. modules { ldap { .... } } authorize { ... ldap } authenticate { ... Auth-Type LDAP { ldap } } When I use a redundant config as per instruction in docs, I have the "auth: No authenticate method (Auth-Type) configuration found for the request: Rejecting the user" in debugs and user is rejected. Please see config and debug output below. I guess I am mussing some fine detail here. Your help would be highly appreciated. modules { ldap ds-01 { .... } ldap ds-02 { .... } } authorize { ... redundant { ds-02 ds-01 } } authenticate { ... Auth-Type LDAP { redundant { ds-02 ds-01 } } } Debug output rad_recv: Access-Request packet from host 1.1.1.1:3283, id=29, length=47 User-Name = "qwer" User-Password = "qwer" Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: No '@' in User-Name = "qwer", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 0 modcall: entering group redundant for request 0 rlm_ldap: - authorize rlm_ldap: performing user authorization for qwer radius_xlat: '(&(objectClass=posixAccount)(l=*)(uid=qwer))' radius_xlat: 'dc=my,dc=com' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: attempting LDAP reconnection rlm_ldap: (re)connect to localhost:389, authentication 0 rlm_ldap: bind as / to localhost:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: performing search in dc=my,dc=com, with filter (&(objectClass=posixAccount)(l=*)(uid=qwer)) rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user alexeim authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ds-02" returns ok for request 0 modcall: leaving group redundant (returns ok) for request 0 modcall: leaving group authorize (returns ok) for request 0 auth: No authenticate method (Auth-Type) configuration found for the request: Rejecting the user auth: Failed to validate the user.
