+   <productname>PostgreSQL</productname> provides various methods for
+   authenticating users:
+
+   <itemizedlist>
+    <listitem>
+     <para>
+      <link linkend="auth-trust">Trust authentication</link>, which
+      simply trusts that users are who they say they are.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-password">Password authentication</link>, which
+      requires that users send a password.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="gssapi-auth">GSSAPI authentication</link>, which
+      relies on a GSSAPI-compatible security library.  Typically this is
+      used to access an authentication server such as a Kerberos or
+      Microsoft Active Directory server.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="sspi-auth">SSPI authentication</link>, which
+      uses a Windows-specific protocol similar to GSSAPI.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-ident">Ident authentication</link>, which
+      relies on an <quote>Identification Protocol</quote> (RFC 1413)
+      service on the client's machine.  (On local Unix-socket connections,
+      this is treated as peer authentication.)
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-peer">Peer authentication</link>, which
+      relies on operating system facilities to identify the process at the
+      other end of a local connection.  This is not supported for remote
+      connections.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-ldap">LDAP authentication</link>, which
+      relies on an LDAP authentication server.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-radius">RADIUS authentication</link>, which
+      relies on a RADIUS authentication server.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-cert">Certificate authentication</link>, which
+      requires an SSL connection and authenticates users by checking the
+      SSL certificate they send.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-pam">PAM authentication</link>, which
+      relies on a PAM (Pluggable Authentication Modules) library.
+     </para>
+    </listitem>
+    <listitem>
+     <para>
+      <link linkend="auth-bsd">BSD authentication</link>, which

+      only on OpenBSD).

+   Peer authentication is usually recommendable for local connections,
+   though trust authentication might be sufficient in some circumstances.
+   Password authentication is the easiest choice for remote connections.
+   All the other options require some kind of external security
+   infrastructure (usually an authentication server or a certificate
+   authority for issuing SSL certificates), or are platform-specific.
