SAML issue with SimpleSAMLphp as IdP, BIG-IP as SP

thanks but i really wouldn't know what to provide configuration wise, i used the default, so configuration of the SP on the BIG-IP isn't much more then making up an ID, importing the meta data from the IdP and making a connection. support: "This message is seen when BIG-IP is configured as SAML service provider (SP) and it does not authenticate if SAML assertion and SAML response are both signed. Authentication will fail. This issue has already been identified as BZ 396735 which is fixed in Eng HF for v11.3 and in v11.4 HF3." F5 support believes i encountered a bug and advise to update to 11.4 SP3, planning to do that this week and will report back.
