Evaluating Group Membership

The IADsGroup::IsMember method takes one argument, the DN of the object to check, just as Add and Remove do. It returns a Boolean; i.e., true or false. That allows you to use it in an If ... Then statement like this:

    Set objGroup = GetObject("LDAP://cn=Managers,ou=Sales," _
      & "dc=mycorp,dc=com")
    If objGroup.IsMember("LDAP://cn=Vicky Launders,ou=Sales," _
      & "dc=mycorp,dc=com") Then
        WScript.Echo "Is a Member!"
    Else
        WScript.Echo "Is NOT a Member!"
    End If

To get a list of members in a group, the IADsGroup::Members method can be used. The IADsGroup::Members function is different from the other IADsGroup methods we have shown so far, since it returns a pointer to an IADsMembers object. Table 23-5 shows the two methods IADsMembers support.

Action

Count

The number of items in the container. If there is a filter set, only the number of items that match the filter are returned.

Filter

A filter, consisting of an array of object class strings, which can restrict the number of objects returned during enumeration of the container.

There are a number of ways of enumerating the members of a group. The For Each ... In ... Next loop is the most common. This is how it works:

    Set objGroup = GetObject("LDAP://cn=Managers,ou=Sales," _
      & "dc=mycorp,dc=com")
    WScript.Echo "Number of members of the group: " & objGroup.Members.Count
    For Each objMember In objGroup.Members
      WScript.Echo objMember.Name
    Next
