(RADIATOR) SIP authentication with SER and Radiator

[Sebastian Vieira]

Hello,

Here we are trying to test SIP authentication with SER and Radiator to 
an LDAP database. Currently the Radiator server is receiving the 
Access-Requests but it is not clear to me how to authenticate it because 
there is no User-Password attribute in the packet. Obviously, with this 
missing attribute, LDAP authentication fails.

Following is the format of one of the access-requests

Code:       Access-Request
Identifier: 119
Authentic:  <148><132>8=1v<239><209><250><208><227>F<173>m<159><134>
Attributes:
        User-Name = "testuser at testrealm"
        Digest-Attributes = <10><12>testuser
        Digest-Attributes = <1><12>testrealm
        Digest-Attributes = <2>*4460f4a30086c04d1edda16c68ad40b4942b153e
        Digest-Attributes = <4><16>sip:testrealm
        Digest-Attributes = <3><10>REGISTER
        Digest-Attributes = <5><6>auth
        Digest-Attributes = <9><10>00000001
        Digest-Attributes = <8><18>84c91b1673a8e22c
        Digest-Response = "c9c04b933351c81ceebbabd9012d70e7"
        Service-Type = Annex-Framed-Tunnel
        Sip-Uri-User = "4609998"
        NAS-Port = 0
        NAS-IP-Address = UNKNOWN

What do I need to do to authenticate this kind of requests?

Regards,

Sebastian
