Feedback on the coturn branch

[Tagadda]

Hi.
As you asked on #29 (comment) I installed the jitsi from the coturn branch, following the instruction on the coturn branch's readme.
I have setup a fresh yunohost container for the occasion. Installation went well, no error of anything.
Two main issues :

• You need to login with LDAP before joining a room. No guest allowed.
• It... doesn't seems to work so well... This may be a problem with my setup tho'
  Several users can join the room, but every users appear with microphone and camera "muted" (cf. screenshot).
  

I'm available to debug things on the freenode yunohost room.
