VMware UAG SAML setup with Keycloak?

This post was originally published on this site



I have the following setup:

Horizon 8.0

UAG 3.10


Wondering if anyone has been able to get Keycloak (Identity Provider) and the VMware UAG working. I run into an issue when I try to upload Keycloak’s SAML metadata file via the UAG Web Interface (Advanced Settings –> Identity Bridging Settings –> Upload Identity Provider Metadat). Error is: Unmapped exception while processing request. See log for details.The admin.log file shows the following:

10/26 10:52:55,464[qtp359806817-573]ERROR exception.UnmappedExceptionMapper[toResponse: 27]: Exception message: {}

java.lang.ClassCastException: class org.opensaml.saml.saml2.metadata.impl.EntitiesDescriptorImpl cannot be cast to class org.opensaml.saml.saml2.metadata.EntityDescriptor (org.opensaml.saml.saml2.metadata.impl.EntitiesDescriptorImpl and org.opensaml.saml.saml2.metadata.EntityDescriptor are in unnamed module of loader org.springframework.boot.loader.LaunchedURLClassLoader @4439f31e)


I attached the XML file I am trying to upload to the UAG.
