Active Directory Properties

Active Directory Properties – LDAP* Fields

Here are the common LDAP attributes which correspond to Active Directory properties.  They are useful for VBScripts which rely on these LDAP attributes to create or modify objects in Active Directory.  For instance if you bulk import users into Active Directory you need to include the LDAP attributes:  dn and sAMAccountName.

* LDAP is the Lightweight Directory Access Protocol.

Topics for Active Directory Properties


Vital LDAP Field – DN  Distinguished Name

The keyword ‘distinguished’ means that this attribute is important, and it uniquely defines an Active Directory object.  Therefore, each DN must have a unique name and location from all other objects in Active Directory. 

Time spent in getting to know the DN attribute will repay many fold.  Observe the different components CN=common name, OU = organizational unit.  DC often comes with two entries, DC=CP, DC=COM.  Note that DC=CP.COM would be wrong.  Incidentally in this situation, DC means domain content rather than domain controller.

Another point with the syntax is to check the speech marks; when used with VBScript commands, DN is often enclosed in "speech marks".  Even the speech marks have to be of the right type, "double quotes are correct", ‘single quotes may be ignored’ with unpredictable results.  Finally, pay particular attention to commas in distinguished names.

LDAP Fields from Active Directory Users and Computers

The diagram below is taken from Active Directory Users and Computers. It shows the commonest LDAP attributes used in VBScript.

LDAP Attributes for CSVDE

It’s worth spending the time to check how the LDAP attributes map to the Active Directory boxes.

One technique that I like to employ is to add values in the boxes, then export using CSVDE, finally open the file in Excel and search for the value.

LDAP Attribute


CN – Common NameCN=Alan Thomas.  Actually, this LDAP attribute is made up from givenName joined to SN.
descriptionWhat you see in Active Directory Users and Computers.  Not to be confused with displayName on the Users property sheet.
displayNamedisplayName = Alan Thomas.  Ensure that you understand which field you are configuring.  DisplayName can be confused with CN or description.
DN – also distinguishedNameDN is simply the most important LDAP attribute.
CN=Jimmy Ward, OU= Newport,DC=cp,DC=com
givenNameFirstname also called Christian name
homeDriveHome Folder : connect.  Tricky to configure
namename = Alan Thomas.  Exactly the same as CN.
objectCategoryDefines the Active Directory Schema category. For example, objectCategory = Person
objectClassobjectClass = User.  Also used for Computer, organizationalUnit, even container.  Important top level container.
physicalDeliveryOfficeNameOffice! on the user’s General property sheet
profilePathRoaming profile path: connect.  Trick to set up
sAMAccountNamesAMAccountName = guyt.  Old NT 4.0 logon name, must be unique in the domain.  Can be confused with CN.
SNSN = Thomas. This would be referred to as last name or surname.
userAccountControlUsed to disable an account.  A value of 514 disables the account, while 512 makes the account ready for logon.
userPrincipalNameuserPrincipalName = [email protected]    Often abbreviated to UPN, and looks like an email address.  Very useful for logging on especially in a large Forest.   Note UPN must be unique in the forest.

LDAP Notes

Display name and Description are different

Office’s LDAP attribute is:


E-mail is plain: mail

Recommended: Solarwinds’ Permissions Analyzer – Free Active Directory ToolFree Permissions Analyzer for Active Directory

I like thePermissions Analyzer because it enables me to see WHO has permissions to do WHAT at a glance.  When you launch this tool it analyzes a users effective NTFS permissions for a specific file or folder, and takes into account network share access, then displays the results in a nifty desktop dashboard!

Think of all the frustration that this free SolarWinds utility saves when you are troubleshooting authorization problems for user’s access to a resource.  Give this permissions monitor a try – it’s free!

Other LDAP attributes

Examples of Exchange Specific LDAP attributes

homeMDB Here is where you set the MailStore
legacyExchangeDNLegacy distinguished name for creating Contacts. In the following example,
Alan Thomas is a Contact in the first administrative group of GUYDOMAIN: /o=GUYDOMAIN/ou=first administrative group/cn=Recipients/cn=Alan Thomas
mailAn easy, but important attribute.  A simple SMTP address is all that is required [email protected]
mAPIRecipient – FALSEIndicates that a contact is not a domain user.
mailNicknameNormally this is the same value as the sAMAccountName, but could be different if you wished.  Needed for mail enabled contacts.
mDBUseDefaultsAnother straightforward field, just the value to:True
msExchHomeServerNameExchange needs to know which server to deliver the mail.  Example:
/o=YourOrg/ou=First Administrative Group/cn=Configuration/cn=Servers/cn=MailSrv
proxyAddressesAs the name ‘proxy’ suggests, it is possible for one recipient to have more than one email address.  Note the plural spelling of proxyAddresses.
 targetAddressSMTP:@ e-mail address.  Note that SMTP is case sensitive.  All capitals means the default address.
 showInAddressBookDisplays the contact in the Global Address List.
