I have a problem with Anyconnect clientless configuration with SAML. I have correctly configured ConnectionProfile, GroupPolicies and SAML Identity Provider. My Identity Provider is a simpleSAMLphp script.
At logon I am redirected to the AnyConnect login page, and in the ASDM log I get an error:
Failed to consume SAML assertion. Reason: The identifier of a provider is unknown to #LassoServer. To register a provider in a #LassoServer object, you must use the lasso_server_add_provider () or lasso_server_add_provider_from_buffer () methods.
