We already have other modules in place, e.g for authentication, like a LDAP, SAML, Google or GitHub as external providers.

If you want to understand how modules work, have a look here:

XO's API can be explored through the xo-cli client (please refer to the previous section for details).

There are modules for a lot of various tasks, like:

  • performance analysis
  • reporting
  • load management
  • various authentication providers

Check your Settings/Plugins view in XOA to see them.
