Hi, I'm authing about 60 3com 4400 switch with mysql. Everithing goes ok until the switch sends a particular request to the server. This is the request: rad_recv: Access-Request packet from host 10.10.0.219:2049, id=57, length=87 User-Name = "a3Com" User-Password = "a3Com" NAS-Port-Type = Virtual NAS-IP-Address = 10.10.0.219 Service-Type = Administrative-User Framed-MTU = 1024 Message-Authenticator = 0xebe1ebfa3372940ad96d932c10457ff8 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 84 modcall[authorize]: module "preprocess" returns ok for request 84 radius_xlat: 'a3Com' rlm_sql (sql): sql_set_user escaped user --> 'a3Com' radius_xlat: 'SELECT id,UserName,Attribute,Value,op FROM radcheck WHERE Username = 'a3Com' ORDER BY id' rlm_sql (sql): Reserving sql socket id: 0 rlm_sql_mysql: query: SELECT id,UserName,Attribute,Value,op FROM radcheck WHERE Username = 'a3Com' ORDER BY id radius_xlat: 'SELECT radgroupcheck.id,radgroupcheck.GroupName,radgroupcheck.Attribute,radgroupcheck.Value,radgroupcheck.op FROM radgroupcheck,usergroup WHERE usergroup.Username = 'a3Com' AND usergroup.GroupName = radgroupcheck.GroupName ORDER BY radgroupcheck.id' rlm_sql_mysql: query: SELECT radgroupcheck.id,radgroupcheck.GroupName,radgroupcheck.Attribute,radgroupcheck.Value,radgroupcheck.op FROM radgroupcheck,usergroup WHERE usergroup.Username = 'a3Com' AND usergroup.GroupName = radgroupcheck.GroupName ORDER BY radgroupcheck.id radius_xlat: 'SELECT id,UserName,Attribute,Value,op FROM radreply WHERE Username = 'a3Com' ORDER BY id' rlm_sql_mysql: query: SELECT id,UserName,Attribute,Value,op FROM radreply WHERE Username = 'a3Com' ORDER BY id radius_xlat: 'SELECT radgroupreply.id,radgroupreply.GroupName,radgroupreply.Attribute,radgroupreply.Value,radgroupreply.op FROM radgroupreply,usergroup WHERE usergroup.Username = 'a3Com' AND usergroup.GroupName = radgroupreply.GroupName ORDER BY radgroupreply.id' rlm_sql_mysql: query: SELECT radgroupreply.id,radgroupreply.GroupName,radgroupreply.Attribute,radgroupreply.Value,radgroupreply.op FROM radgroupreply,usergroup WHERE usergroup.Username = 'a3Com' AND usergroup.GroupName = radgroupreply.GroupName ORDER BY radgroupreply.id rlm_sql (sql): Released sql socket id: 0 modcall[authorize]: module "sql" returns ok for request 84 modcall: group authorize returns ok for request 84 auth: type Local auth: user supplied User-Password matches local User-Password Login OK: [a3Com] (from client XXXXXXXXX port 0) Sending Access-Accept of id 57 to 10.10.0.219:2049 Finished request 84 Going to the next request This is OK, but switch says "The RADIUS Authentication service is not responding." The strange thing is the userame a3Com that i've never seen in any switch configuration. Is something related to including dictionary.3Com in dictionary file ? I've googled a lot and searched in 3Com knowledge base but can't find anything.
