VBscript to retrieve userWorkstation attribute from AD.

[wlfpackr]

So I've run into a rather confusing issue with a script I'm writing to update userWorkstations attribute. Below is a simplified version of what I'm doing (hopefully with no typos):

strUserDN = "CN=username,OU=Users,DC=xyz,DC=com"

Set objUser = GetObject("LDAP://" & strUserDN)
strUser = objUser.Get("samaccountname")
strComps = objUser.Get("userWorkstations")
 
 WScript.Echo "User: " & strUser & vbCrLf & "Workstations: " & strComps

It works fine if the userWorkstation attribute is populated, but if it's empty I get an error:

Error: The directory property cannot be found in the cache
Code:  8000500D
Source:  Active Directory

If I run the code with a valid user DN that has information in the userWorkstation attribute, script works fine. If I run the code with a valid user DN that does not have any information in the userWorkstation attribute, the error above is returned and refers to strComps = objUser.Get("userWorkstations").

I tried using an If/Then statement with <> "" or IsNull() but that doesn't work either. Any suggestions other than an On Error Resume Next? I'd like to understand what is actually going on.

So I took a shot in the dark and used the following code:

strUserDN = "CN=username,OU=Users,DC=xyz,DC=com"

Set objUser = GetObject("LDAP://" & strUserDN)
strUser = objUser.samaccountname
strComps = objUser.userWorkstations
 
 WScript.Echo "User: " & strUser & vbCrLf & "Workstations: " & strComps

[\code]

It works without any problem.  I would love to know why?
