No it's not done because it's impossible without storing
the plaintext passwords in smbpasswd.

The Windows clients will send the plaintext of the new
password (encrypted) to the password change server, but
they don't possess the plaintext of the old password,
just the Lanman or NT hash of it (which is of no use
for NIS passwords).

Sorry, but that's the real reason why %o cannot be 
supported when using encrypted password change support.
