SSO/HTTP
From Authentication Tools for Joomla! (JAuthTools)
HTTP Authentication utilises server provided authentication mechanisms to identify and authorize the users request.
For Apache, numerous solutions do exist, a small selection below:
- Basic
- Kerberos
- LDAP (e.g. user lookup)
- DBD (e.g. MySQL, Postgres, Oracle, etc)
For IIS, there are limited options:
- Basic (NTLM)
- Kerberos (Negotiate)
For either major system, further user details rely on parent schemes (e.g. LDAP provided by AD/eDirectory; MySQL DB with user information) provided by Users Sources to autocreate and manage users if necessary.
