VBScript to enable/disable “manager can update membership list” checkbox

Managing this checkbox proves harder than expected. The managedBy value is an attribute, but the checkbox is a delegation of control setting on the member attribute of the group object you put the managedBy value on.

'Usage: cscript "CN=Group,OU=Groups,DC=Tools4ever,DC=local" DC01.tools4ever.local T4EVMDEMO 1
'Make sure the managedBy attribute is already set, as this script reads the user from that attribute and adds the appropriate delegation of the member attribute to the group object
strGroup = wscript.arguments(0) 'DN of Group
strDomainController = wscript.arguments(1) 'DC FQGN used to bind to group
strDomainNT4 = wscript.arguments(2) 'NETBIOS domain name for the group
intEnabled = wscript.arguments(3) '1 for enabled, 0 for disabled
