Hi,


I'm using CAS 5.0.0.RC3-SNAPSHOT with SAML2 support.


Since this version I got an issue with authentication (authentication works
with RC1).

I think the issue comes from these
lines(cas/support/cas-server-support-saml-idp/src/main/java/org/apereo/cas/support/saml/web/idp/profile/builders/enc/SamlObjectSigner.java)
:

l.409 : if (!overrideBlackListedSignatureAlgorithms.isEmpty()) {

and

l.414 : if (!overrideWhiteListedAlgorithms.isEmpty()) {



Should it be :

l.409 : if (this.overrideBlackListedSignatureAlgorithms != null &&
!this.overrideBlackListedSignatureAlgorithms.isEmpty()) {

and

l.414 : if (this.overrideWhiteListedAlgorithms != null &&
!overrideWhiteListedAlgorithms.isEmpty()) {



Or is there a properties to set this 2 list to empty ones?


I got the following stackTrace (full stacktrace in attachment) :
