Al, I think the null pointer is on the bypass check rather than something about the list of attributes. It is possible that SAML IdP adds a slightly different flow; maybe it does not check for null.
Can you use a groovy script?

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Not sure if this is a weird local config or some sort of bug. I have these set globally in cas.properties. cas.authn.mfa.duo[0].bypass.principal-attribute-name=mfaDisable cas.authn.mfa.duo[0].bypass.principal-attribute-value=nomfa When SAML IdP support is included in the WAR overlay with: implementation "org.apereo.cas:cas-server-support-saml-idp", I get a NullPointerException after the Duo Push when the mfaDisable attribute is null. and I include it in the list of released attributes in the service definition like this: "attributeReleasePolicy" : { "@class" : "org.apereo.cas.services.ReturnAllowedAttributeReleasePolicy", "allowedAttributes" : [ "java.util.ArrayList", [ "cn", "mail", "sn", "uid", "displayName", "memberOf", "mfaDisable", "sAMAccountName", "departmentNumber" ] ] } If I remove it from this list, there is no exception. The departmentNumber attribute is also null and does not trigger the exception. If the mfaDisable attribute has a value, the exception is not triggered. Also, if I remove SAML IdP support from the WAR overlay, it does not trigger an exception. My workaround for now is to remove the mfaDisable attribute while keeping SAML support.
