+Date: Mon, 10 Jun 2024 23:00:03 +0300
+Subject: [PATCH 48/53] support authentication indicators in GSSAPI
+
+RFC 6680 defines a set of GSSAPI extensions to handle attributes
+associated with the GSSAPI names. MIT Kerberos and FreeIPA use
+name attributes to add information about pre-authentication methods used
+to acquire the initial Kerberos ticket. The attribute 'auth-indicators'
+may contain list of strings that KDC has associated with the ticket
+issuance process.
+
+Use authentication indicators to authorise or deny access to SSH server.
+GSSAPIIndicators setting allows to specify a list of possible indicators
+that a Kerberos ticket presented must or must not contain. More details
+on the syntax are provided in sshd_config(5) man page.
+
+Fixes: https://bugzilla.mindrot.org/show_bug.cgi?id=2696

++Specifies whether to accept or deny GSSAPI authenticated access if Kerberos
++mechanism is used and Kerberos ticket contains a particular set of
++authentication indicators. The values can be specified as a comma-separated list
++.Cm [!]name1,[!]name2,... .
++When indicator's name is prefixed with !, the authentication indicator 'name'
++will deny access to the system. Otherwise, one of non-negated authentication
++indicators must be present in the Kerberos ticket to allow access. If
++.Cm GSSAPIIndicators
++is defined, a Kerberos ticket that has indicators but does not match the
++policy will get denial. If at least one indicator is configured, whether for
++access or denial, tickets without authentication indicators will be explicitly
++rejected.
++.Pp
++By default systems using MIT Kerberos 1.17 or later will not assign any
++indicators. SPAKE and PKINIT methods add authentication indicators
++to all successful authentications. The SPAKE pre-authentication method is
++preferred over an encrypted timestamp pre-authentication when passwords used to
++authenticate user principals. Kerberos KDCs built with Heimdal Kerberos
++(including Samba AD DC built with Heimdal) do not add authentication
++indicators. However, OpenSSH built against Heimdal Kerberos library is able to
++inquire authentication indicators and thus can be used to check for their presence.
++.Pp
++Indicator name is case-sensitive and depends on the configuration of a
++particular Kerberos deployment. Indicators available in MIT Kerberos and

-configure.ac: Improve C99 compatibility

-Future compilers will not support implicit declarations and implicit
-ints by default.  This means that configure probes which rely on them
-will fail unconditionally, without actually testing anything.

-the two versions of configure.ac.
