We're Running a Policy Server, and in the Federation Journey, we see
that the SAML Responses show duplicated ID and as such the SP side
cannot consume the assertion.
How can we fix this ?
This is corrected in Policy Server 12.8SP1 :
Defects Fixed in 12.8.01
Single sign-on fails as Policy Server issues duplicate assertion IDs in an assertion.
Policy Server 12.8SP0CR00 on RedHat 7;
Policy Server JDK 1.8.0_181;
Policy Store on CA Directory 14.0;
Admin UI 12.8SP1 on Windows 2012 R2 ;
We suggest you to upgrade to the latest version 12.8SP02 in order to
insure to have all the latest fix including this one.
