Problem Note 50747: A client machine connects to a server machine even when the connection should not be allowed
 |  |  |  |  |
In UNIX operating environments, a client might be able to connect to a server even when the connection should not be allowed. This problem occurs when a Secure Sockets Layer (SSL) certificate uses a wildcard in the Common Name. The wildcard certificate verifies authenticity even when it should not be allowed to do so.
For example, suppose that a spawner is invoked with SSL encryption on a server named foobar.xyz.company-name.com. Then you have a client that uses an SSL certificate with a wildcard of *.AAA.company-name.com (rather than *.xyz.company-name.com) for the Common Name. In this situation, a connection between the client and server might be enabled even though it should not be allowed.
