Available fields for ADSI Linked in SQL Server

Question

We currently have a View that queries active directory info. I was wondering if there was a good reference as to what fields (field names) are available in AD for me to query against. I don't have access to Active Directory so I can't go playing around in there to maybe figure it out myself. Any help would be appreciated.

Answer 1

Active Directory uses LDAP v3. This version specifies that any fields may be modified, added, and removed, but in order for AD to work properly there are many fields it retains. You can view the schema for your AD instance by going to the domain controller and using the schema editor (in MMC) to view the available fields, but as you said you do not have access to those resources. Here are the common attributes used across most LDAP implementations:

givenName: first name

sn: last name

telephoneNumber: phone number

streetAddress: street address

l: city

st: state

c: country

postalCode: zip code

Answer 2

There's a really good set of references at Richard Mueller's site - he has Excel sheets about the AD properties, how they map to the "Active Directory Users & Computers" tool, and how to search using ADO - lots of good stuff!
