IdP v4 SLO issues when wilcard certificates for websites

[Lipscomb, Gary]

Hi List,

RHEL 7
Tomcat 9
OpenJDK 11


I’m in the process of upgrading to IdP v4 (4.0.1) and have come across an issue with SLO which was not present in v3.4.7

When we try to SLO and the web certificate for that site uses a wildcard certificate (e.g. *.csu.edu.au) SLO fails with the following error

2020-08-14 15:09:53,138 - 10.0.2.2 - ERROR [org.opensaml.security.x509.impl.BasicX509CredentialNameEvaluator:297] - Credential failed name check: [subjectName='CN=*.csu.edu.au,OU=DIT,O=Charles Sturt University,L=North Wagga,ST=New South Wales,C=AU']

2020-08-14 15:09:53,311 - 10.0.2.2 - WARN [net.shibboleth.idp.saml.saml2.profile.impl.SOAPLogoutRequest:298] - Profile Action SOAPLogoutRequest: SOAP logout request failed
org.opensaml.soap.common.SOAPException: Problem handling SOAP message exchange with: https://onlinedevel.csu.edu.au/Shibboleth.sso/SLO/SOAP
        at org.opensaml.soap.client.http.AbstractPipelineHttpSOAPClient.send(AbstractPipelineHttpSOAPClient.java:244)
Caused by: org.opensaml.messaging.handler.MessageHandlerException: Message context was not authenticated
        at org.opensaml.messaging.handler.impl.CheckMandatoryAuthentication.doInvoke(CheckMandatoryAuthentication.java:70)

These sites are behind a load balancer and the wild card certificate is used extensively.
Is there a setting I’ve missed in the upgrade process?

Regards

Gary
