This is continuance of existing support ticket

Atm, Archibus REST api only supported when the security is configured using Single sign on (SAML)

Please test / support Archibus REST api, when Archibus authentication OR LDAP authentication is selected for the security ? This is currently giving an error "Authentication must be not null"

I just thought that with more and more people using the REST api as part of the integration, we will encounter issues where customers who have no identity system that supports Single sign on at its front end.
