Where are PostgreSQL passwords stored?

PostgreSQL database passwords are separate from operating system user passwords. The password for each database user is stored in the pg_authid system catalog. Passwords can be managed with the SQL commands CREATE USER and ALTER ROLE, e.g., CREATE USER foo WITH PASSWORD 'secret'. If no password has been set up for a user, the stored password is null and password authentication will always fail for that user.

What is GSSAPI in PostgreSQL?

GSSAPI is an industry-standard protocol for secure authentication defined in RFC 2743. PostgreSQL supports GSSAPI with Kerberos authentication according to RFC 1964. GSSAPI provides automatic authentication (single sign-on) for systems that support it. The authentication itself is secure, but the data sent over the database connection will be sent unencrypted unless SSL is used.

When does GSSAPI support need to be enabled?

GSSAPI support has to be enabled when PostgreSQL is built; see Chapter 15 for more information.

What happens if you set realm to 0?

If set to 0, the realm name from the authenticated user principal is stripped off before being passed through the user name mapping ( Section 19.2 ). This is discouraged and is primarily available for backwards compatibility as it is not secure in multi-realm environments unless krb_realm is also used. Users are recommended to leave include_realm set to the default (1) and to provide an explicit mapping in pg_ident.conf.

Does PostgreSQL support a parameter?

PostgreSQL also supports a parameter to strip the realm from the principal. This method is supported for backwards compatibility and is strongly discouraged as it is then impossible to distinguish different users with the same user name but coming from different realms. To enable this, set include_realm to 0. For simple single-realm installations, include_realm combined with the krb_realm parameter (which checks that the realm provided matches exactly what is in the krb_realm parameter) would be a secure but less capable option compared to specifying an explicit mapping in pg_ident.conf.

Can you use client principals in PostgreSQL?

Alternatively, you can use the full username@realm principal as the role name in PostgreSQL without any mapping.

Does PostgreSQL use SSPI?

PostgreSQL will use SSPI in negotiate mode, which will use Kerberos when possible and automatically fall back to NTLM in other cases. SSPI authentication only works when both server and client are running Windows, or, on non-Windows platforms, when GSSAPI is available.

What is max_connections in PostgreSQL?

At most max_connections connections can ever be active simultaneously. Whenever the number of active concurrent connections is at least max_connections minus superuser_reserved_connections, new connections will be accepted only for superusers, and no new replication connections will be accepted.

Why is PostgreSQL using server preferences better?

Using the server's preferences is usually better because it is more likely that the server is appropriately configured.
