Description (partial)

Symptom:
AuthnContext being sent by ADFS 4.0 is urn:oasis:names:tc:SAML:2.0:ac:classes:Kerberos and not urn:federation:authentication:windows therefore the IDS doesn't accept it and throw below error:

com.cisco.ccbu.ids SAML2DebugFile.java:41 - SAML2Utils.isAuthnContextMatching: AuthnContextClassRef urn:oasis:names:tc:SAML:2.0:ac:classes:Kerberos is not supported

UCCE 12.5 feature guide mentions to disable form-based authentication for kerberos to work :
