You'll also want to allow passwords longer than 8 characters. AIX won't throw an error, but if your password is "abcd123456", then it only uses "abcd1234" since it uses the legacy Unix crypt subroutine by default.
/etc/security/pwdalg.cfg lists the available password algorithms...
select the algorithm you want to use in /etc/security/login.cfg:
pwd_algorithm = ssha256
Heh, yeah. It's probably a SUS or POSIX thing, the same thing is true on Solaris.
