SUMMARY
On the Security tab of the SNA Server subdomain, an LUA check box exists to allow user-validated security for LUA applications. However, this does not apply to TN3270 LUA LUs. Even though TN3270 LUA LUs can be assigned to users in SNA Server Manager, no user validation will occur.



MORE INFORMATION
TN3270 uses Telnet to communicate between the client and the server by encapsulating 3270 data in Telnet sessions to the TN3270 Service. Telnet is a TCP/IP protocol that uses IP addressing to determine the source and destination of packets. No user credentials are passed to the TN3270 Service for validation.
