HI, The freeradius is comunicate with the IAS through a proxy, but dont authenticate. The windows show me this error: "Event type: Error Source: IAS A malformed request was received from client XXXX. The data is the packet." The freeradius debug: modcall[authorize]: module "auth_log" returns ok for request 3 modcall[authorize]: module "chap" returns noop for request 3 rlm_realm: Looking up realm "voip.domain.br" for User-Name = "teste@voip.domain.br" rlm_realm: Found realm "DEFAULT" rlm_realm: Proxying request from user teste to realm DEFAULT rlm_realm: Adding Realm = "DEFAULT" rlm_realm: Preparing to proxy authentication request to realm "DEFAULT" modcall[authorize]: module "suffix" returns updated for request 3 rlm_digest: Adding Auth-Type = DIGEST modcall[authorize]: module "digest" returns ok for request 3 rlm_ldap: - authorize rlm_ldap: performing user authorization for teste@voip.domain.br radius_xlat: '(uid=teste@voip.domain.br)' radius_xlat: 'ou=users,dc=voip,dc=domain,dc=br' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in ou=users,dc=voip,dc=domain,dc=br, with filter (uid=teste@voip.domain.br) rlm_ldap: object not found or got ambiguous search result rlm_ldap: search failed rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns notfound for request 3 modcall: leaving group authorize (returns notfound) for request 3 Sending Access-Request of id 3 to 10.2.1.XY port 1600 User-Name = "teste@voip.domain.br" Digest-Attributes = 0x0a077465737465 Digest-Attributes = 0x010e766f69702e756662612e6272 Digest-Attributes = 0x022a34353039343233343264313165616336306262366262633263373539643630666362383939656131 Digest-Attributes = 0x04127369703a766f69702e756662612e6272 Digest-Attributes = 0x030a5245474953544552 Digest-Response = "4283445dcb36643dab5f437e10f692bf" Service-Type = IAPP-Register X-Ascend-PW-Lifetime = 0x7465737465 NAS-IP-Address = 10.2.1.XX NAS-Port = 5060 Proxy-State = 0x323038 Re-sending Access-Request of id 0 to 10.2.1.XX port 1600 User-Name = "teste@voip.domain.br" Digest-Attributes = 0x0a077465737465 Digest-Attributes = 0x010e766f69702e756662612e6272 Digest-Attributes = 0x022a34353039343233343264313165616336306262366262633263373539643630666362383939656131 Digest-Attributes = 0x04127369703a766f69702e756662612e6272 Digest-Attributes = 0x030a5245474953544552 Digest-Response = "4283445dcb36643dab5f437e10f692bf" Service-Type = IAPP-Register X-Ascend-PW-Lifetime = 0x7465737465 NAS-IP-Address = 10.2.1.XX NAS-Port = 5060 Client-IP-Address = 10.2.1.XX Realm = "DEFAULT" Module-Failure-Message = "rlm_ldap: User not found" Realm = "DEFAULT" Proxy-State = 0x323035 Waking up in 1 seconds... rad_recv: Access-Request packet from host 10.2.1.XX:33634, id=206, length=200 Ignoring duplicate packet from client OpenSER:33634 - ID: 206, due to outstanding proxied request 1. What is worng? I dont undestand: freeradius and IAS use the same protocol... It is attribute question? Cryptografy? Please any Idea... a tip… anybody already had some similar experience? I tried in some ways: |Openser| -> |Freeradius| -> |AD| |Openser| -> |Radiusclient| -> |IAS| -> |AD| |Openser| -> |Freeradius| -> |IAS| -> |AD| help! thanks... --------------------------------- O Yahoo! está de cara nova.
