BUG: [Object].GUID Results Differ from [Object].Get("GUID")

ID: Q215355

The information in this article applies to:

SYMPTOMS

When attempting to retrieve a directory object's GUID from an LDAP directory, using [object].GUID produces different results than using [object].Get("GUID").


CAUSE

Because of a bug in the LDAP ADSI Provider that ships with ADSI 2.0, using the syntax [object].GUID returns the GUID for the Class object, whereas using the syntax [object].Get("GUID") returns the actual GUID of the object you are currently bound to.


RESOLUTION

When retrieving an object's GUID, use the Get() method to retrieve the attribute value as in this example: 

[object].Get("GUID")


STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.


MORE INFORMATION

Steps to Reproduce Behavior

To reproduce this issue, you must bind to an LDAP object that supports a GUID attribute, such as a Member object in the Site Server 3.0 Membership Directory. The following code demonstrates this: 

Dim adsRoot
Dim strLdapPath

strLdapPath = "LDAP://myserver:389/o=Microsoft/ou=Members/cn=MyUser"

'Bind to the object
Set adsRoot = GetObject(strLdapPath)

'Display a Message Box with the incorrect GUID attribute
Msgbox "The incorrect value is: " & CStr(adsRoot.GUID)

'Display a Message Box with the correct value
Msgbox "The correct value is: " & CStr(adsRoot.Get("GUID"))

'Clean up
Set adsRoot = Nothing
