Extra options for Greenlight

The Web-Frontend has some extra configuration options, listed below:

SMTP

The notifications are sent using sendmail, unless the bbb_greenlight_smtp.server variable is set. In that case, make sure the rest of the variables are properly set.

The default value for bbb_greenlight_smtp.sender is bbb@{{ bbb_hostname }}

Example Setup:

bbb_greenlight_smtp:
  server: smtp.gmail.com
  port: 587
  domain: gmail.com
  username: [email protected]
  password: yourpassword
  auth: plain
  starttls_auto: true
  sender: [email protected]

LDAP

You can enable LDAP authentication by providing values for the variables below. Configuring LDAP authentication will take precedence over all other providers. For information about setting up LDAP, see: https://docs.bigbluebutton.org/greenlight/gl-config.html#ldap-auth

Example Setup:

bbb_greenlight_ldap:
  server: ldap.example.com
  port: 389
  method: plain
  uid: uid
  base: dc=example,dc=com
  bind_dn: cn=admin,dc=example,dc=com
  password: password
  role_field: ou

GOOGLE_OAUTH2

For in-depth steps on setting up a Google Login Provider, see: https://docs.bigbluebutton.org/greenlight/gl-config.html#google-oauth2 The bbb_greenlight_google_oauth2.hd variable is used to limit sign-ins to a particular set of Google Apps hosted domains. This can be a string with separating commas such as, 'domain.com, example.com' or a string that specifies a single domain restriction such as, 'domain.com'. If left blank, GreenLight will allow sign-in from all Google Apps hosted domains.

bbb_greenlight_google_oauth2:
  id:
  secret:
  hd:

OFFICE365

For in-depth steps on setting up a Office 365 Login Provider, see: https://docs.bigbluebutton.org/greenlight/gl-config.html#office365-oauth2

bbb_greenlight_office365:
    id:
    secret:
    hd:

In Application Authentication

By default, the ability for anyone to create a Greenlight account is enabled. To disable this, use false. For more information see: https://docs.bigbluebutton.org/greenlight/gl-config.html#in-application-greenlight

bbb_greenlight_accounts: false

RECAPTCHA

To enable reCaptcha on the user sign up, define these 2 keys. You can obtain these keys by registering your domain using the following url: https://www.google.com/recaptcha/admin

bbb_greenlight_recaptcha:
  site_key:
  secret_key:

METEOR

With settings bbb_meteor it is possible to overwrite / change settings of meteor.

LXD/LXC compatibility

To run BigBlueButton in unprivileged LXD/LXC containers, you have to set bbb_container_compat to true.

Phone dial-in

Example configuration using sipgate for dial-in. Be sure to check with your provider if this usage is permitted.

bbb_dialin_enabled: true
bbb_dialin_provider_proxy: 'sipgate.de'
bbb_dialin_provider_username: '158d43584d'

bbb_dialin_mask_caller: true
bbb_dialin_overwrite_footer: true

Dependencies

Pitfalls

Greenlight - Server Error: "Invalid BigBlueButton Endpoint and Secret"

Check your /etc/hosts file if your dns name (example meet.domain.tld) has the IP 127.0.1.1. Docker will use the internal system DNS to resolve meet.domain.tld to 127.0.1.1 which will result in this error. Edit this line and replace 127.0.1.1 with your public IP.
