The etherpad component's nginx configuration needs to know the request
scheme in order to set some variables that influence whether the
'Secure' flag is set on cookies. Right now it directly uses the $scheme
variable, but this variable does not get set to the expected value if
nginx is behind a reverse-proxy where the proxy handles TLS termination.
Adjust the etherpad nginx config to use a variable with a different name
$real_scheme, which can be set in the nginx server block to match the
configuration of the nginx listeners.
This variable is set to the value of $scheme in the default
/etc/sites-available/bigbluebutton file. The bbb-install.sh script will
be updated to set this variable in the configurations it writes.
People using other installation scripts will need to add this variable
to their nginx configuration file, or etherpad might not operate correctly.
Etherpad uses the sessionID cookie for authorization. In cluster setups the
host part of the URI which serves the html5 frontend is different from
the hostname part of the URI which serves etherpad. Therefore the
bbb-html5 client can't set a cookie for etherpad which contains the
etherpad sessionID.
This patch uses the `ep_auth_session` etherpad plugin which takes the
`sessionID` as query parameter, sets the cookie in the browser and
redirects the iframe to the pad URI.
Since bbb-pads user's name is set internally by akka-apps and bbb-pads internal
credentials exchange. Yet, Etherpad's embedded URL params still work and the user
could use it to ovewrite.
Use nginx rules to block an access attempt that contains the userName argument.
Move all Etherpad's access control from Meteor to a separated [Node application](https://github.com/bigbluebutton/bbb-pads).
This new app uses [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
to create groups and manage session tokens for users to access them. Each group
represents one distinct pad at the html5 client.
- Removed locked users' access to pads: replaced readOnly pad's access with a new pad's content sharing routine
- Pad's access is now controlled by [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
- Closed captions edited content now reflects at it's live feedback
- Improved closed caption's dictation mode live feedback
- Moved all Etherpad's API control from Meteor to a separated [app](https://github.com/bigbluebutton/bbb-pads)
- Included access control both in akka-apps and bbb-pads
