Novell LINUX ENTERPRISE SERVER 11 - SECURITY Manual page 43

3b Define whether the host should also be a NIS client, enabling users to log in
and access data from the NIS server, by selecting This Host is also a NIS
Client.
Select Allow Changes to Passwords to allow users in your network (both
local users and those managed through the NIS server) to change their
passwords on the NIS server (with the command yppasswd). This makes
the options Allow Changes to GECOS Field and Allow Changes to Login
Shell available. "GECOS" means, that the users can also change their names
and address settings with the command ypchfn. "SHELL" allows users to
change their default shell with the command ypchsh, for example, to switch
from bash to sh. The new shell must be one of the predefined entries in
/etc/shells.
3c If your NIS server should act as a master server to NIS slave servers in other
subnets, select Active Slave NIS Server Exists.
The option Fast Map Distribution is only useful in conjunction with Active
Slave NIS Servers Exist. It speeds up the transfer of maps to the slaves.
3d Select Open Port in Firewall to have YaST adapt the firewall settings for
the NIS server.
