The ticket + file will be removed after request is handled. + ++Constrained Delegation ++---------------------- ++S4U2Proxy, or constrained delegation, enables a service to use a client's ++ticket to itself to request another ticket for delegation. The KDC ++checks krbAllowedToDelegateTo to decide if it will issue a new ticket. ++If KrbConstrainedDelegation is enabled the server will use its own credentials ++to retrieve a delegated ticket for the user. For this to work the user must ++have a forwardable ticket (though the delegation flag need not be set). ++The server needs a valid credentials cache for this to work. ++ ++The module itself will obtain and manage the necessary credentials. ++ + $Id: mod_auth_kerb-5.4-s4u2proxy-r2.patch,v 1.1 2015/05/08 18:21:14 pacho Exp $ +diff -up --recursive mod_auth_kerb-5.4.orig/src/mod_auth_kerb.c mod_auth_kerb-5.4/src/mod_auth_kerb.c +--- mod_auth_kerb-5.4.orig/src/mod_auth_kerb.c 2011-12-09 17:55:05.000000000 -0500 ++++ mod_auth_kerb-5.4/src/mod_auth_kerb.c 2012-03-01 14:19:40.000000000 -0500 +@@ -42,6 +42,31 @@ + * POSSIBILITY OF SUCH DAMAGE. + */ + ++/* ++ * Locking mechanism inspired by mod_rewrite. ++ * ++ * Licensed to the Apache Software Foundation (ASF) under one or more ++ * contributor license agreements.
