Am I correct in assuming that AIX (5.2 and 5.3) /still/ doesn't
support the use of md5 encrypted NIS passwords? I use md5 encryption
with my Linux NIS passwords and my AIX NIS clients, when I try to su
to a user, gives me this error after I enter the password:

3004-501 Cannot su to "joeuser" : Authentication is denied.

Or is there some flag I can turn on on the AIX machine that will allow
it to send it's request to the NIS server md5 encrypted?
