Types of Client Logons
The number of logons required for establishing an SNA session from a client varies, depending mostly on what client/server protocol the client computer is using. The following list describes the logons:
Clients Using Microsoft Networking
A client using Microsoft Networking must log on to the Windows domain and then must perform any logons required on the mainframe or IBM i. For example, a client using Microsoft Networking and also using a 5250 emulator would log on once to the Windows domain, once to the IBM i itself, and (in many cases) once to the IBM i program that communicates with the 5250 emulator.
After clients using Microsoft Networking are logged on to the domain, no additional logon is needed for access to Host Integration Server computers in the domain. That is, Host Integration Server can securely confirm the domain logon without any additional action by the user.
Clients Using TCP/IP
A client using TCP/IP must log on to the Host Integration Server computers even if the client has already accessed other resources in the Windows domain, and then must perform any logons required on the mainframe or IBM i.
