From f9961e5f82e0ef474d6492371bfdf9e74e208a99 Mon Sep 17 00:00:00 2001 From: Pavel Březina Date: Tue, 19 Mar 2013 15:53:44 +0100 Subject: DNS sites support - SRV lookup plugin interface https://fedorahosted.org/sssd/ticket/1032 Introduces two new error codes: - ERR_SRV_NOT_FOUND - ERR_SRV_LOOKUP_ERROR Since id_provider is authoritative in case of SRV plugin choise, ability to override the selected pluging during runtime is not desirable. We rely on the fact that id_provider is initialized before all other providers, thus the plugin is set correctly. --- src/providers/fail_over_srv.h | 72 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 src/providers/fail_over_srv.h (limited to 'src/providers/fail_over_srv.h') diff --git a/src/providers/fail_over_srv.h b/src/providers/fail_over_srv.h new file mode 100644 index 000000000..0796ad5ab --- /dev/null +++ b/src/providers/fail_over_srv.h @@ -0,0 +1,72 @@ +/* + Authors: + Pavel B??ezina + + Copyright (C) 2013 Red Hat + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
