The system administrator may optionally restrict connections via SSH2/Telnet based upon the user id. This is useful when you have a defined set of users that you would allow access to the Windows NT/XP/VISTA/2000/2003/2008 Server via SSH2/Telnet. If the system administrator decides to limit the users allowed to logon via SSH2/Telnet then the local group Gwtn Users must be created.
If this group exists then only members of this group will be allowed to logon via SSH2/Telnet. If this group does not exist then all users that can logon locally can log on via SSH2/Telnet. Once the group Gwtn Users is created, each user allowed to logon via SSH2/Telnet must be added to this group
