Rollin,
Here's the query that does what you are looking for (you will need to change the domain info). There's some free downloads on the internet that will let you browse the AD database but I don't have access to the one I normally use.

SELECT * 
   FROM OPENROWSET('ADsDSOObject','Active Directory Provider',
      'SELECT displayName, sAMAccountName, mail
         FROM ''LDAP://dc=buediamond,dc=com'' WHERE objectCategory = ''User''')
