[Documentation] Additional authentication and authorization options #689
Description
Relevant documentation
refarch-gateway
Problem description (optional)
Currently we only support OAuth 2.0 / OpenID Connect but not every company has an according auth provider and therefore can't reuse RefArch applications.
It was decided to not add additional auth sources into the RefArch but document an easy Keycloak setup.
See #688
Desired solution
Describe how to use RefArch with no existing auth provider:
- Keycloak or other simple provider setup
- Links on how to configure LDAP and Sign-In via Username and Password
