2 20.14. BSD Authentication #
4 This authentication method operates similarly to password except that
5 it uses BSD Authentication to verify the password. BSD Authentication
6 is used only to validate user name/password pairs. Therefore the user's
7 role must already exist in the database before BSD Authentication can
8 be used for authentication. The BSD Authentication framework is
9 currently only available on OpenBSD.
11 BSD Authentication in PostgreSQL uses the auth-postgresql login type
12 and authenticates with the postgresql login class if that's defined in
13 login.conf. By default that login class does not exist, and PostgreSQL
14 will use the default login class.
18 To use BSD Authentication, the PostgreSQL user account (that is, the
19 operating system user running the server) must first be added to the
20 auth group. The auth group exists by default on OpenBSD systems.
