Exchange 2013 CU2 Hybrid Configuration Wizard - Certificate name too long

I am trying to run the Hybrid Configuration Wizard on Exchange 2013 CU2.  When selecting the certificate I am getting the "length of the property is too long. The maximum length is 256...".  The purchased certificate is 306 in length, but it was my understanding that MS changed the tlsCertificateName parameter with a higher upperRange setting per this kb: http://support.microsoft.com/kb/2860844/en-us

Can anyone tell me where this parameters exists?  We tried combing through the schema and registry and came up with nothing.  Also, can anyone confirm that MS actually included this fix in CU2?

Thanks!
