Push to active directory fails without error - asp-classic

Question

I apologise if I have posted this before, but I am struggling with this script to push data into Active Directory. The following code works, i.e. it does not produce any errors, but it doesn't update the directory. I have the following code:
<%# Language=VBScript %>
<% response.Buffer = True
'Define the AD OU that contains our users
dim ADUser, user, firstname, lastname, email, telephonenumber, mobile, description
'This initializes all of our variables
user = request.querystring("account_name")
'This puts the value of the account_name into a variable
if len(user) = 0 then
'If the length of the username is equal to 0
response.write "Please supply a username in the query string"
elseif len(user) > 0 then
'Else is length of user is greater than 0
ADUser = "LDAP://OU=RBC Staff,OU=RBC Users,DC=rugby,DC=internal"
' Make AD connection and run query
Set objCon = Server.CreateObject("ADODB.Connection")
objCon.provider ="ADsDSOObject"
objCon.Properties("User ID") = "EXAMPLE\User"
objCon.Properties("Password") = "Password01"
objCon.Properties("Encrypt Password") = TRUE
objCon.open "Active Directory Provider"
Set objCom = CreateObject("ADODB.Command")
Set objCom.ActiveConnection = objCon
objCom.CommandText ="select givenName,sn,mail,telephonenumber,mobile,description, sAMAccountName, cn FROM '"+ ADUser +"' where sAMAccountname='"& user &"'"
Set objRS = objCom.Execute
If IsNull(objRS.Fields("Description").Value) Then
sDesc = ""
else
For Each item In objRS.Fields("description").Value
sDesc = item
Next
end if
if isNull(objRS("givenName")) then
firstname = ""
else
firstname = objRS("givenName")
end if
if isNull(objRS("sn")) then
lastname = ""
else
lastname = objRS("sn")
end if
if isNull(objRS("mail")) then
email = ""
else
email = objRS("mail")
end if
if isNull(objRS("telephonenumber")) then
telephonenumber = ""
else
telephonenumber = objRS("telephonenumber")
end if
if isNull(objRS("mobile")) then
mobile = ""
else
mobile = objRS("mobile")
end if

set writeLDAP = update.Execute
Do While Not writeLDAP.EOF
Set usr = GetObject(writeLDAP.Fields("ADsPath").Value)
usr.Put "gjvenName", firstname

The only thing I can think of is that, the login I used wasn't a domain admin account.
