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.
Where is the keytab file in PostgreSQL?
(See also Section 17.1 .) The location of the key file is specified by the krb_server_keyfile configuration parameter. The default is /usr/local/pgsql/etc /krb5.keytab (or whatever directory was specified as sysconfdir at build time). For security reasons, it is recommended to use a separate keytab just for the PostgreSQL server rather than opening up permissions on the system keytab file.
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.
