When doing mutual authentication web service integration, by default, the ‘com.glide.communications.trustmanager_trust_all’ property is set to false. The Now platform only trusts certificates that it can verify against the JVM certificate store.

However, in many cases, the certificate in a project is self-signed or enterprise-signed, in this case, the value of the property has to be set as ‘true’ for ServiceNow to download client WSDL and generate SOAP functions.
