Fast answer:

sed ':a;N;$!ba;s/\n/ /g' file

1. :a create a label 'a'
2. N append the next line to the pattern space
3. $! if not the last line, ba branch (go to) label 'a'
4. s substitute, /\n/ regex for new line, / / by a space, /g global match (as many times as it can)

Third Party Authentication Features in Open edX: Technical Knowledge Transfer

Part 1: Background / Notes

• Open edX has full, integrated support for three different types of third party auth provider:
  1. OAuth based providers (OAuth2 and the older OAuth v1). Google, Facebook, LinkedIn, and Azure Active Directory are available by default. Any other OAuth backends supported by python-social-auth v0.2.12 can be enabled by changing a configuration setting. Contributed by Google (John Cox).
  2. SAML / Shibboleth. SAML is an SSO standard mostly used by universities and corporations. Shibboleth is the name of a particular implementation of SAML, commonly used by higher ed. institutions.
  3. LTI. Users can use Learning Tools Interoperability® (LTI®) to authenticate. Support for this was contributed by UBC.
• The Open edX platform also includes limited support for the following SSO providers.
