//  Function:   GetDomainFromLDAPPath
//
//  Synopsis:   returns a freshly allocated string containing the LDAP path
//              to the domain name contained with an arbitrary LDAP path.
//
//  Arguments:  [szIn] - LDAP path to the initial object
//
//  Returns:    NULL - if no domain could be found or if OOM
//
//  History:     5-06-1998   stevebl   Created
//              10-20-1998   stevebl   modified to preserve server names
//
//  Notes:      This routine works by repeatedly removing leaf elements from
//              the LDAP path until an element with the "DC=" prefix is
//              found, indicating that a domain name has been located.  If a
//              path is given that is not rooted in a domain (is that even
//              possible?) then NULL would be returned.
//
//              The caller must free this path using the standard c++ delete
//              operation. (I/E this isn't an exportable function.)
