From 5952755755fb0ea7f942bb564ca1cfdca5730113 Mon Sep 17 00:00:00 2001 From: Alexander Bokovoy Date: Wed, 3 Apr 2013 16:37:00 +0300 Subject: [PATCH] PASSDB: add support to set and enumerate UPN suffixes associated with our forest Samba PDC may manage a forest containing DNS domains in addition to the primary one. Information about them is advertised via netr_DsRGetForestTrustInformation when trusted_domain_name is NULL, according to MS-NRPC and MS-LSAD, and via netr_GetForestTrustInformation. This changeset only expands PASSDB API; how suffixes are maintained is left to specific PDB modules. Set function is added so that suffixes could be managed through 'net' and other Samba utilities, if possible. One possible implementation is available for ipasam module in FreeIPA: http://git.fedorahosted.org/cgit/freeipa.git/commit/?id=cc56723151c9ebf58d891e85617319d861af14a4 Reviewed-by: Andreas Schneider --- source3/include/passdb.h | 18 ++++++++++++++++- source3/passdb/ABI/pdb-0.sigs | 2 ++ source3/passdb/pdb_interface.c | 36 ++++++++++++++++++++++++++++++++++ 3 files changed, 55 insertions(+), 1 deletion(-) diff --git a/source3/include/passdb.h b/source3/include/passdb.h index 908631de315..5e5a7bfa58c 100644 --- a/source3/include/passdb.h +++ b/source3/include/passdb.h @@ -412,9 +412,10 @@ enum pdb_policy_type { * Changed to 18, pdb_rid_algorithm -> pdb_capabilities * Changed to 19, removed uid_to_rid * Changed to 20, pdb_secret calls + * Changed to 21, set/enum_upn_suffixes.
