Bug description: Passhook plugin used to store the password in
the intermediate file passhook.dat using _snprintf which just
converts wchar in ascii to char without considering the non-
ascii characters.

Fix description: Instead of using _snprintf, WideCharToMultiByte?
is called to convert the Microsoft internal character set to
UTF-8, which is valid in LDAP.

Also, in SyncPasswords? (PassSync?), it adds LDAP_INAPPROPRIATE_
AUTH to the condition to send the password change on Windows to
the Directory server. Bind returns LDAP_INAPPROPRIATE_AUTH,
when a password is not in the entry for SIMPLE auth. PassSync?
should be able to send the password for the case, as well.
