I have a server running the Manager Server Edition. It runs the accounting software for my girlfriends company, which works great. My brother also has a company and asked me if he could use my server. I want him to give a full access account for his own company, so he can change his own settings and make his own backups. As far as I know, this is only possible with an administrator account. However, I would not prefer to make him administrator since he than can also access the business of my girlfriend.
To get around this, I tried to run a second instance of Manager Server, on a different port and with a different path. Unfortunately I did not manage to get this working (Snow Leopard Server on a Mac Mini). Is this even possible or is there a better solution?
