Answer 1

I doubt the attribute name is Name, and try displayName instead in this line:

"<LDAP://dc=domain,dc=com>;(objectCategory=User);Name;Subtree" 

Answer 2

ended up getting with this

Set objConnection = CreateObject("ADODB.Connection")

Set objCommand = CreateObject("ADODB.Command")  

objConnection.Open "Provider=ADsDSOObject;" 
objCommand.ActiveConnection = objConnection  

strDomainName = "dc=domain,dc=com" 
strUserCN = username 
objCommand.CommandText = "<LDAP://" & strDomainName & ">;(&(objectCategory=person)     (objectClass=user)(cn=" & strUserCN & "));displayName;subtree"  

Set objRecordSet = objCommand.Execute  

If Not objRecordset.EOF Then  

strray = split(objRecordSet.Fields("displayName"),"(") 
strdat = strray(0)



username = trim(strdat)

End If
