[Pam-mysql-general] replacing /etc/passwd?

[Ian P. C. <po...@po...>]

Am I correct in assuming that this does not *replace* /etc/passwd?

I've been playing with this module for a while now, and the only way I can
get it to work is if a user exists in /etc/passwd.

Just for experimentation, I have edited /etc/pam.d/su to use auth via sql.
When I try to su to a user that is in the database, and not in /etc/passwd,
I get 'Unknown id: <user>'.
Is this right?

I was hoping I could replace the entire user auth system with a mysql
database. is this not possible?

Many Thanks,

Ian.
