Error description
An MQ managed .NET client application which sets the CertficateLabel via a HashTable or MQEnvironment properties in uppercase fails to connect to the queue manager with a RC=2059 when the FriendlyName of the certificate in windows certificate store is in uppercase as well. The queue manager logs AMQ9637 error AMQ9637: During handshake, the remote partner sent no certificate.
Local fix
Use a lowercase CertificateLabel via hash table or via MQEnvironment when using a upper case Friendly name for the certificate added to windows certificate store.
