help with remote auth / fail over password sync

[Chris Stankaitis]

Hello All,

I am using a remote auth system (pgina) which has a pam module which
allows me to auth users against a remote server, is it possible to do
the following:

If Auth response from the server = OK & the client password and server
password differ take the server password as 'proper' and update the
clients shadow file to sync the passwords.

This is in the event that the remote server is down and the box has to
then auth against local credentials.

Thanks.

Chris
