Jitsi OpenID

Jitsi OpenID is an authentication adapter to provide jitsi the ability to use single sign on via OpenID Connect.

Deployment

This guide is based of the docker setup from jitsi.

This image is available in the GitHub Container Registry:

ghcr.io/marcelcoding/jitsi-openid:latest

Docker "run" Command

docker run \
  -p 3000:3000 \
  -e JITSI_SECRET=SECURE_SECRET \
  -e JITSI_URL=https://meet.example.com \
  -e JITSI_SUB=meet.example.com \
  -e ISSUER_URL=https://id.example.com \
  -e BASE_URL=https://auth.meet.example.com \
  -e CLIENT_ID=meet.example.com \
  -e CLIENT_SECRET=SECURE_SECRET \
  --rm \

      #    default: ''
    ports:
      - '3000:3000'

To generate the JITSI_SECRET you can use one of the following command:

cat /dev/urandom | tr -dc a-zA-Z0-9 | head -c128; echo

Jitsi Configuration

If you have problems understating this have a look here: #80

# for more information see:
# https://github.com/jitsi/docker-jitsi-meet/blob/master/env.example

# weather to allow users to join a room without requiring to authenticate
#ENABLE_GUESTS=1

# fixed
ENABLE_AUTH=1
AUTH_TYPE=jwt

# should be the same as JITSI_ID of jitsi-openid environment variables
JWT_APP_ID=meet.example.com
# should be the same as JITSI_SECRET of jitsi-openid environment variables
JWT_APP_SECRET=SECRET

# fixed values
JWT_ACCEPTED_ISSUERS=jitsi
JWT_ACCEPTED_AUDIENCES=jitsi

# auth.meet.example.com should be the domain name of jitsi-openid,
# `/room/{room}` is the endpoint that's jitsi redirecting the user to
# `{room}` is is a placeholder, where jitsi inserts the room name
# jitsi-openid should redirect the user after a successfully authentication
# !! it is recommend to use ALWAYS https e.g. using a reverse proxy !!
TOKEN_AUTH_URL=https://auth.meet.example.com/room/{room}

Jitsi JWTs

The JWTs are populated using the data returned by your IDP. This includes the user id, email and name.

The sub extracted from the prefered_username field, if that isn't preset the sub field is used.

The name is extracted from the name field, if that isn't preset a concatenation of given_name, middle_name and family_name is used. If all tree of them are also not present the prefered_username is used.

The affiliation is straight up passed, without any modifications or alternatives. It can be used to restrict the permissions a user has in a specific room in jitsi. See https://github.com/jitsi-contrib/prosody-plugins/tree/main/token_affiliation for more information.

The picture (avatar) URL is delegated from the IDP to Jitsi.
