[Serusers] IP phone ---> SER ---> freeradius ---> ldap

Hi all, I'm trying to authentificate ser users against ldap. IP phone ---> SER ---> freeradius ---> ldap Everything's working well exept the username who's passed to ldap. The user is passed with username@realm and I want just the username. After googling a long while and trying to modify the realm module entry in radiusd.conf, I can't find the right config in the config files. Is the problem in the ser config or the radius config. Thanks in advance for you help. rad_recv: Access-Request packet from host 127.0.0.1:32852, id=114, length=200 User-Name = "test(a)192.168.16.33" Digest-Attributes = 0x0a0674657374 Digest-Attributes = 0x010f3139322e3136382e31362e3333 Digest-Attributes = 0x022a34323932316232373363653965396436623336653063306233376334366234316135356235656339 Digest-Attributes = 0x04137369703a3139322e3136382e31362e3333 Digest-Attributes = 0x030a5245474953544552 Digest-Response = "aade5df3a90732fd1a221d3ce43f7c96" Service-Type = Sip-Session Sip-Uri-User = "test" NAS-IP-Address = 127.0.0.1 NAS-Port = 5060 rlm_digest: Converting Digest-Attributes to something sane...
