// Function: LdapCrackUserDNToNTLMUser
//
// Synopsis: This call attempts to translate an LDAP-style DN into an NTLM
// domain password form. The algorithm is to assume that the first
// component will be of the form "CN=krishnaG" . This first component
// will be taken as the user name. The subsequent components are
// scanned till we find the first DC= component.
//
// Arguments: [LPTSTR szBuffer]
// [LPVOID *ppObject]
//
// Returns: HRESULT
//
// Modifies: -
//
// History: 11-3-95 krishnag Created.
