NetWare 6.5 post-SP5 NSS 5A, eDir

We started to have issues with password changing. User would be prompted to
change their password, but would get an error (Error fffffec.1) when they
try. Finding that uninstalling NMAS would solve the issue. Since doing so,
now our Site Admins can't change passwords from ConsoleOne. They get the
error "The application has failed to start because nmas.dll was not
found...." Then "(Error -215) Multiple meaning error message for error
code -215."

So I guess the question is, what's the right combination/version of these
component so I can have a harmonious password situation?

Thank you,
