MORE INFORMATION
For detailed information about installation and architecture of Host Security, see the Microsoft Knowledge Base article 175063, "Host Security Integration Setup and Architectural Overview."

Steps to Reproduce the Problem:

The steps below assume a Host Security Domain is installed and correctly configured.  In SNA Server Manager, configure two connections to a single AS/400. Two remote APPC LUs should be configured, one for each connection. A single local APPC LU is acceptable. In SNA Server Manager, assign only one of the connections to the Host Security Domain. Save the configuration file and restart SNA Server. Start the 5250 applet, select the connection assigned to the Host Security Domain, and select Automatic Logon. Attempt to connect to the AS/400. The connection is successful. Disconnect from the AS/400 and reconfigure the session. Select the connection that is not assigned to the Host Security Domain and leave Automatic Logon selected. Try to connect to the AS/400. The session fails with the following message:

"The SNA session is unavailable [0010][00000000]."

In the Windows NT Server Application Event Log, the following is logged:

Event 38

APPC session deactivated abnormally

Qualifier

0003 and Event 90

APPC protocol violation

Sense data=0C001110





SYMPTOMS
Automatic Logon using the 5250 applet can fail even though a Host Security Domain has been successfully configured.



CAUSE
Host Security Domains require assignment of connections for correct operation. Session configuration of the 5250 applet allows user selection of Automatic Logon and connection. Automatic Logon fails if the connection selected by the user is not assigned to the Host Security Domain.

RESOLUTION
To resolve this problem, assign all connections in the SNA Subdomain to the Host Security Domain. SNA Server must be restarted for the change to take effect. This allows Automatic Logon over all connections.
