Virtual Domains

[MicroSense Computer Works]

I am currently running Paul Greggs method of working with virtual domains.  Works Great.=20 The only problem that I have with it is administration.  I don't want to write my own user / Domain manager to add and delete accounts (nor do I want to do it manually) Any good suggestions on an easy to use virtual domain manager. PS. I like the idea that I don't have to add system accounts or touch any of the /etc password files to use Paul Greggs way of doing things.
