20.14. BSD Authentication
This authentication method operates similarly to
password
except that it uses BSD Authentication
to verify the password. BSD Authentication is used only
to validate user name/password pairs. Therefore the user's role must
already exist in the database before BSD Authentication can be used
for authentication. The BSD Authentication framework is currently
only available on OpenBSD.
BSD Authentication in
PostgreSQL
uses
the
auth-postgresql
login type and authenticates with
the
postgresql
login class if that's defined
in
login.conf
. By default that login class does not
exist, and
PostgreSQL
will use the default login class.
Note
To use BSD Authentication, the PostgreSQL user account (that is, the
operating system user running the server) must first be added to
the
auth
group. The
auth
group
exists by default on OpenBSD systems.
