Hosting Multiple Domains on SBS 2003 (Part 3)

Now you are hosting multiple domains (by following Part 1 & Part 2), your users are all confused on how to log in, what their email address is and where to go. How do you seperate these things?

Well, you use UPN Suffixes.

UPN stands for User Principal Name, which is essentially a fancy computer-lingo'd way of saying: use your e-mail address to log in.

When you enable this, users will be able to go to the Remote Web Workplace and log in using their email address, instead of just their username. Might make it easier to give some users their email address instead of explaining the username versus email address idea.

How to set it up:

1. Click on Start, Administrative Tools, Active Directory Domains and Trusts


2. In the console that loads, right click on the root node called Active Directory Domains and Trusts and choose Properties


3. Add your domain suffixes in in the format domain.com

Now your AD knows that it is the root domain controller responsible for these domains.

Close out this console and go back into Server Management. In the Users snap-in, we need to tell the AD what the primary suffix is for each user:

1. Right-click a user and choose Properties


2. On the Account tab, change the drop down box for the User logon name to be the suffix you want this user to have. Note it will add the '@' sign for you, if you see 2 '@' signs, you've done the first step wrong


3. Choose OK for that user

You'll have to repeat this for all the users in your AD, but when you are finished, you can give your users an email address and a password, they won't need that funky "username".

It made life less confusing for my grandfather, that's for sure. :o)

One last thing. Since SBS shares the AD with all domains, you cannot have two aliases the same, so you should use combination usernames of first and last name, instead of just "dave" or "sean", otherwise user on domain1 might have the "cool" user name, while user on domain2 does not.
