Hello,
I successfully installed Greenligth 2.3 using LDAP authentication.
However, I had difficulty understanding the authentication failure after setting LDAP parameters in the .env file.
The documentation is missing the need to install ldap-rails as a mandatory requirement.
I didn't see this in the documentation:
https://docs.bigbluebutton.org/greenlight/gl-customize.html#ldap-authAfter installation with "gem install ldap-rails" command, authentication was OK
