netgroup and user management how to

[francisk at auston.com]

Hi ! Nis user group
I have setup my nis server and client successfully with Redhat 8. 
Presently server is NT server. I would like to migrate all my users to 
Linux NIS. I would like to know what is the best way to management 
my users. 

1) I have about 25 departments and 70 users. Members of each 
department can only view and alter the files and folders in their 
department. Also, I have a public folder where everybody can save, 
copy or edit a file and directory there. What is the best way to do 
this. Should I create each department in /etc/group then assign the 
right permission.

2) I have read about the netgroup but not quite understand. Can 
anyone tell me what it does ? I only have one nis domain and one 
linux nis server. Should I use the netgroup to manageme my user or 
just use the /etc/group (groupadd) 

3) If I have two nisdomain is it advise to use the netgroup ?

Appreciate if you can help.
