[otrs] Disable company ticket view for certain users

Hi, How can I have a group of, say, 50 customer users belonging to one company, where only 10 of them can see all company tickets (i.e. the tickets of the 50 users of the same company) and the other 40 users can only see their own tickets? P.S. I'm using 3.0.0-beta2. Thanks for any suggestion, -- -- Jos Vos -- X/OS Experts in Open Systems BV | Phone: +31 20 6938364 -- Amsterdam, The Netherlands | Fax: +31 20 6948204
