I don't think any of the developers has access to MP-RAS, much less
implemented OpenSSH support for account lockin on it.

If you are interested in implementing better support for MP-RAS, then
see if you can dig out some documentation of how the FAILLIMIT is
implemented, and any system APIs for working with it.

As a last resort you might be able to set UseLogin in sshd_config, which
will cause sshd to call /usr/bin/login directly and will hopefully
inherit whatever authorisation controls that it supports.
