This guide describes how mod_auth_mellon can be configured as a SAML Service Provider for eduTEAMS.
mod_auth_mellon is an authentication module for Apache. It authenticates the user against a SAML 2.0 IdP, and grants access to directories depending on attributes received from the IdP. It used to be maintained by Uninett, but is now in the community. The code and documentation can be found at https://github.com/latchset/mod_auth_mellon.
