Where user workstations are already authenticated to the network the browser will automatically pass the Windows security principle ID to the Framework which will in turn use this to authenticate the user against the LDAP store.

Factonomy is also able to use SAML (Security Assertion Mark-up Language) in authenticating connections from the system server to other data providers typically using web services and XML.
