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. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Exchange 2000 Server, or both. 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.


When you use the LDP utility (Ldp.exe) to connect to a domain controller and view attributes, some values contain the phrase Binary BLOB, which signifies Binary Large Objects.


BLOB is used whenever a string is multivalued. To view the contents of a binary BLOB, you can use two tools: Ldp.exe (in binary mode), and ADSIEdit.

To view the contents of a binary BLOB with LDP, choose Options, choose General, change Value Parsing to "binary," and then double-click the object. The values are displayed on the right side of the screen.

To view the contents of a binary BLOB with ADSIEdit, connect to the Distinguished Name, and select the attribute from the drop-down list.
