Type mismatch on Join

I have created a script to map a drive based on group membership. Here is a listing of the applicable lines in the script:

====================================================
' Create required objects
Set wshNetwork = CreateObject("WScript.Network")
Set objSysInfo = CreateObject("ADSystemInfo")
Set wshShell = WScript.CreateObject("WScript.Shell")
set objFSO = createobject("Scripting.FileSystemObject")

' Get users' username
Set CurrentUser = GetObject("LDAP://" & objSysInfo.UserName)

' Get user's group list
strGroups = LCase(Join(CurrentUser.MemberOf))

' Map network drives
If InStr(strGroups, "cn=Corporate") Then
      wshNetwork.MapNetworkDrive "Q:", "\\BNESRV1\CORPORATE"
End If
====================================================

When a user run the script the following error is displayed:

\\bnesrv1\netlogon\logon.vbs(11, 1) Microsoft VBScript runtime error: Type mismatch: 'Join'

The script runs OK as a Domain Admin and I have also tested the script with the user being an administrator on the local machine.

Any ideas?
Thanks in advance.

Try check whether your value pass in is an array or not.

Example:

..
If IsArray(CurrentUser.MemberOf) Then
   strGroups = LCase(Join(CurrentUser.MemberOf))
Else
   strGroups = LCase(CurrentUser.MemberOf)
End if
..

This shud solve:

dim grp

' Get user's group list

strGroups = ""
for each grp in CurrentUser.MemberOf
   strGroups = strGroups & " " & LCase(grp)
next grp


use this, instead of the join thing.

Generally, something like this member of property, wud return a collection or an object collection etc.
Join works for arrays only.

Thanks for the replies.

I tried this one:

If IsArray(CurrentUser.MemberOf) Then
   strGroups = LCase(Join(CurrentUser.MemberOf))
Else
   strGroups = LCase(CurrentUser.MemberOf)
End if

And it runs the join for a domain admin, but the Else statement for a user. Now that's get me stumped.

This one give me 'object not a collection'

for each grp in CurrentUser.MemberOf
   strGroups = strGroups & " " & LCase(grp)
next grp

First, we need to know what is returned from CurrentUser.MemberOf, seems that it's not a collection, which is not allow in the for each statement.

and what's the data type of CurrentUser, how you declare this variable?

run the :

If IsArray(CurrentUser.MemberOf) Then
   strGroups = LCase(Join(CurrentUser.MemberOf))    '<----set a breakpt here
Else
   strGroups = LCase(CurrentUser.MemberOf)    '<----set a breakpt here
End if

set a break point at thsoe 2 places and add the "currentuser.memberof " to the watch.
This will display the object structure. Based on that u can decide how to join the grps.

U could also do this stuff in anotehr way.

as in, what u want is to check if a user is in grp "Corporate" and if so, map the network drive.

There is some method to check directly if a user is a group, given the user and grp name.

>>"And it runs the join for a domain admin, but the Else statement for a user. Now that's get me stumped."

This could be coz the admin is a memeber of multiple grp and the user has only one grp.
