FIX: Session Integrator in Host Integration Server 2010 may return an error message when it connects to a TN3270 SSL-enabled port on an IBM mainframe: "Server certificate check failed"
Article ID: 2782858 - View products that this article applies to.
Consider the following scenario:
In this scenario, if the certificate on the IBM mainframe is large, Session Integrator may return the following exception when it connects to the IBM mainframe system:
Microsoft.HostIntegration.SNA.Session.SessionException: Server certificate check failed
For example, this problem occurs when the certificate that is used for the TN3270 SSL connection is 4,000 bytes long. This problem does not occur when the certificate is 1,500 bytes long.
This problem occurs because Session Integrator incorrectly reads the certificate data.
