I'm trying to migrate from IIS to RedHat 9 and I'm a little lost as to how to set up the authentication permissions for the Apache web server on a private sub-domain. I’ve read the .htaccess documentation at Apache’s site and I think I know less than when I originally started researching the problem.

Here’s my scenario:

Domain Stucture

I have a site free.website.com that is public. I have a series of sub-domains (ie. pay1.website.com, pay2.website.com, pay3.website.com) with restricted access to our paid subscribers.

User Groups

I have three levels of subscribers; full, complementary, and demo users for the premium sub-domains. Full subscribers get access to all the sub-domains; Comp’d users get access to pay1.website.com & pay2.website.com; and, Demo users only pay1.website.com.

I've always used the user manager in IIS for authentication which allows you to assign multiple groups access to a directory via the properties selection in Windows Explorer. Is there a similar method for me to do this in RedHat? I really need to be able to use a GUI interface if at all possible. I also have Webmin installed on the box.

Thanks in advance.
