Does the samba server on your AIX box run with security = SERVER?  If
so, I remember reading something about how security = SERVER can result
in lockouts because first samba sends a bogus password that gets denied
to make sure that it is actually meaningful that the real password gets
accepted.  I think there are other issues with security = SERVER too,
and if you can swing security = DOMAIN, that is probably the way to go.

If you have security = DOMAIN using winbindd, does it happen shortly
after users change their password?
