How to use the ADSI Edit Utility to Look up Attributes. (4351611)

I have migrated a user but I don't know whether the SID History was added or not.

I would like to make sure my target user, which was merged with two different accounts, has two SID History attributes applied.

I would like to know which attribute I have to skip, if I want to skip First Name and Last Name.

I would like to clean up some attributes, how can I delete custom attributes or extension attributes?

To answer these questions and any question related to attributes, you can use the Microsoft ADSI Edit utitlity, which is part of the Windows 2000 and later Support Tools.  Ensure you have these tools installed.

The ADSI Edit Utility:

If you have Windows 2000 or Windows 2003 Support Tools installed you can use the Microsoft Management Console (MMC) Active Directory Schema snap-in.

1. Start | Run and type in adsiedit.msc.

2. Right-click on ADSI EDit under Console root and select "connect to".  If you want to connect to local machine you don't have to specify the name, just click OK.

3. Expand the domain and OU, find the (user) object, right-click and select Properties.

Note:  ADSI Edit Uses the Currently Logged on User to authenticate to the Active Directory

Warning:  If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk. Quest does not provide support for problems that arise from improper modification of the Active Directory Object attributes.
