I have installed odssey access client on windows 2008 R2 and try to select a machine cert to do machine cert authentication. But a unexpected error prompt while selecting cert: Some certificates could not be listed. Invalid provider type specified. But i still click ok and select the cert and another error prompt: You do not have a private key that corresponds to this certificate. .... Anyone answer me whether the OAC supports windows 2008 server R2 ? Please note that the certificate is working on windows 7 and other windows platforms. Thanks!!! ... View more
