We had a similar question in case 1477887.
The answer was: "Windows Integrated authentication allows to configure both Kerberos v5 authentication and NTLM authentication. This is just a configuration on IIS level and nothing to do with ACRM. Basic authentication via username/password is also supported. There is no support for SAML v2.
ACRM Web and ACRM Designer supports Windows Authentication (NTLM, Kerberos or any other provider supported by IIS) and Basic Authentication".
Please let me know if you need more details.
