I'm using a simple TURN server string turn://username:password@127.0.0.1:3478.

Starting TURN Server itself using turnserver -L 127.0.0.1 --lt-cred-mech --fingerprint -u username:password -X public_ip/127.0.0.1 -v.

The result is this:

However, when testing with https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ the log looks different and everything works fine:

6: session 007000000000000001: delete: realm=<>, username=<username>

So from GStreamer/libnice logs it seems that username is not being sent at all.
