ProxyRestrictionConditionValidator is missing in the OpenSaml4AuthenticationProvider.SAML20AssertionValidators class

[ek-ma]

Error
An error is triggered when trying to validate an Assertion that contains a ProxyRestriction as one of its conditions. The following error is displayed :
Invalid assertion [xxx] for SAML response [xxx]: Unknown Condition '{urn:oasis:names:tc:SAML:2.0:assertion}ProxyRestriction' of type 'null' in assertion 'xxx'

It may be due to the fact that the conditions present in the OpenSaml4AuthenticationProvider.SAML20AssertionValidators do not include the ProxyRestrictionConditionValidator.

Expected behavior
The expected behavior is to have all of the conditions

Thanks,

Thanks for the report, @ek-ma! This is now merged and will go out in the next maintenance release.
