How to configure WebRTC with Coturn and oAuth - oauth

Question

I want to use coturn with oAuth. If I understood it correctly I need to do two things:
Storing the oAuth tokens in the database coturn is using
Sending the ACCESS-TOKEN and USERNAME STUN attributes
First point is clear but how do I need to change my WebRTC client to achieve the second point?
Without oAuth I would initialize my RTCPeerConnection like this:
var configuration = {
'iceServers': [{
'url': 'turn:turn.example.org',
'username': 'user',
'credential': 'password'
}]
};
var pc = new RTCPeerConnection(configuration)
The WebRTC 1.0 draft defines a RTCIceCredentialType enum so i would think I need to change my configuration like this:
var configuration = {
'iceServers': [{
'url': 'turn:turn.example.org',
'username': 'kid',
'credential': 'oAuthToken',
'credentialType': 'token'
}]
};
Using Wireshark I can't see the ACESS-TOKEN attribute. Any ideas or does anyone know a working example?

Answer 1

It seems like things changed a bit since original question was asked. The webrtc-pc#1033 pull-request alters the spec and introduces the following iceServers configuration syntax:
var configuration = {
'iceServers': [{
"urls": "turns:turn.example.net",
"username": "username",
"credential": {
"macKey": "...",
"accessToken": "..."
},
"credentialType": "oauth"
}],
...
}
See RTCIceServer documentation page for more configuration examples.
