From fc02c3b0890a9549989bb0aba16588026c6d6b43 Mon Sep 17 00:00:00 2001 From: Dan Sledz Date: Fri, 13 Feb 2009 12:28:57 -0800 Subject: [PATCH] Introduce a new passdb backend: pdb_onefs_sam Implements a custom backend for onefs that exclusively uses the wbclient interface for all passdb calls. It lacks some features of a standard passdb. In particular it's a read only interface and doesn't implement privileges. --- source3/Makefile.in | 4 + source3/configure.in | 3 +- source3/passdb/pdb_onefs_sam.c | 433 +++++++++++++++++++++++++++++++++++++++++ 3 files changed, 439 insertions(+), 1 deletion(-) create mode 100644 source3/passdb/pdb_onefs_sam.c diff --git a/source3/Makefile.in b/source3/Makefile.in index a0bd4ab3034..6087fa03598 100644 --- a/source3/Makefile.in +++ b/source3/Makefile.in @@ -2364,6 +2364,10 @@ bin/tdbsam.@SHLIBEXT@: $(BINARY_PREREQS) passdb/pdb_tdb.o @echo "Building plugin $@" @$(SHLD_MODULE) passdb/pdb_tdb.o +bin/onefs_sam.@SHLIBEXT@: $(BINARY_PREREQS) passdb/pdb_onefs_sam.o + @echo "Building plugin $@" + @$(SHLD_MODULE) passdb/pdb_onefs_sam.o + bin/smbpasswd.@SHLIBEXT@: $(BINARY_PREREQS) passdb/pdb_smbpasswd.o @echo "Building plugin $@" @$(SHLD_MODULE) passdb/pdb_smbpasswd.o diff --git a/source3/configure.in b/source3/configure.in index 41140aed345..7fe824c9892 100644 --- a/source3/configure.in +++ b/source3/configure.in @@ -1104,7 +1104,7 @@ echo $samba_cv_HAVE_ONEFS if test x"$samba_cv_HAVE_ONEFS" = x"yes"; then AC_DEFINE(HAVE_ONEFS,1,[Whether building on Isilon OneFS]) default_shared_modules="$default_shared_modules vfs_onefs vfs_onefs_shadow_copy perfcount_onefs" - default_static_modules="$default_static_modules auth_onefs_wb" + default_static_modules="$default_static_modules auth_onefs_wb pdb_onefs_sam" ONEFS_LIBS="-lisi_acl -lisi_ecs -lisi_event -lisi_util" # Need to also add general libs for oplocks support save_LIBS="$save_LIBS -lisi_ecs -lisi_event -lisi_util -ldevstat" @@ -6146,6 +6146,7 @@ SMB_MODULE(pdb_ldap, passdb/pdb_ldap.o passdb/pdb_nds.o, "bin/ldapsam.$SHLIBEXT" [ PASSDB_LIBS="$PASSDB_LIBS $LDAP_LIBS" ] ) SMB_MODULE(pdb_smbpasswd, passdb/pdb_smbpasswd.o, "bin/smbpasswd.$SHLIBEXT", PDB) SMB_MODULE(pdb_tdbsam, passdb/pdb_tdb.o, "bin/tdbsam.$SHLIBEXT", PDB) +SMB_MODULE(pdb_onefs_sam, passdb/pdb_onefs_sam.o, "bin/onefs_sam.$SHLIBEXT", PDB) SMB_SUBSYSTEM(PDB,passdb/pdb_interface.o) diff --git a/source3/passdb/pdb_onefs_sam.c b/source3/passdb/pdb_onefs_sam.c new file mode 100644 index 00000000000..51b8618aad8 --- /dev/null +++ b/source3/passdb/pdb_onefs_sam.c @@ -0,0 +1,433 @@ +/* + Unix SMB/CIFS implementation. + Password and authentication handling for wbclient + Copyright (C) Andrew Bartlett 2002 + Copyright (C) Jelmer Vernooij 2002 + Copyright (C) Simo Sorce 2003 + Copyright (C) Volker Lendecke 2006 + Copyright (C) Dan Sledz 2009 + + 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.
