[K12OSN] Multiple logins UPDATE

[norbert]

Hi,

Thanks for the suggestion but I'm no further ahead.. well... at least 
users can still login, the same user can login multiple times .
The script give me an "syntax error: unexpected end of file"
What I need is also select the group that the users belong to prior to 
limiting their login, ie if 'groups | grep -q rhsstudents' then limit 
the login.

What should be a simple task has turned into a nightmare .....

thks again for all the help
