Hi Every body! I'm setting up an Eduroam infrastructure authenticating through a LDAP directory. I conveniently configure realms for local request and remote request as well. But, i'm dealing with empty user attribute issue while attempting to authenticate with the eduroam user. It seems that although the request is proxied, my server tries to locally check the authorized attributes of the user against my local ldap server. And since no such user exists ldap returns : object not found Thu Jan 5 20:19:26 2012 : Debug: rlm_ldap: object not found Thu Jan 5 20:19:26 2012 : Debug: search failed Thu Jan 5 20:19:26 2012 : Debug: rlm_ldap: ldap_release_conn: Release Id: 0 Thu Jan 5 20:19:26 2012 : Debug: modsingle[authorize]: returned from ldap (rlm_ldap) for request 0 Thu Jan 5 20:19:26 2012 : Debug: ++[ldap] returns notfound Next, my server proxies an other request with empty attributes certainly resulting from the previous object found result : Sending Access-Request of id 144 to 193.190.198.59 port 1812 User-Name := "" User-Password := "" Service-Type := Authenticate-Only Message-Authenticator := 0x00000000000000000000000000000000 NAS-Identifier := "Status Check. Are you alive?" Thu Jan 5 20:19:47 2012 : Debug: No response to status check 3 from home server 193.190.198.59 port 1812 What may have been misconfigured ? Note : The home server is alive since i test it through radtest command Please see here in attachment the log of user authentication attempt Thanks for your help. Eric ATTOU
