The adex idmap/nss_info plugin is an adapation of the Likewise Enterprise plugin with support for OU based cells removed (since the Windows pieces to manage the cells are not available). This plugin supports * The RFC2307 schema for users and groups. * Connections to trusted domains * Global catalog searches * Cross forest trusts * User and group aliases Prerequiste: Add the following attributes to the Partial Attribute Set in global catalog: * uidNumber * uid * gidNumber A basic config using the current trunk code would look like [global] idmap backend = adex idmap uid = 10000 - 19999 idmap gid = 20000 - 29999 idmap config US:backend = adex idmap config US:range = 20000 - 29999 winbind nss info = adex winbind normalize names = yes winbind refresh tickets = yes template homedir = /home/%D/%U template shell = /bin/bash ----------------------------------------------------------------------- Summary of changes: source3/Makefile.in | 12 + source3/configure.in | 1 + source3/winbindd/idmap_adex/cell_util.c | 292 ++++++ source3/winbindd/idmap_adex/domain_util.c | 278 ++++++ source3/winbindd/idmap_adex/gc_util.c | 848 +++++++++++++++++ source3/winbindd/idmap_adex/idmap_adex.c | 460 +++++++++ source3/winbindd/idmap_adex/idmap_adex.h | 257 +++++ source3/winbindd/idmap_adex/likewise_cell.c | 425 +++++++++ source3/winbindd/idmap_adex/provider_unified.c | 1180 ++++++++++++++++++++++++ 9 files changed, 3753 insertions(+), 0 deletions(-) create mode 100644 source3/winbindd/idmap_adex/cell_util.c create mode 100644 source3/winbindd/idmap_adex/domain_util.c create mode 100644 source3/winbindd/idmap_adex/gc_util.c create mode 100644 source3/winbindd/idmap_adex/idmap_adex.c create mode 100644 source3/winbindd/idmap_adex/idmap_adex.h create mode 100644 source3/winbindd/idmap_adex/likewise_cell.c create mode 100644 source3/winbindd/idmap_adex/provider_unified.c Changeset truncated at 500 lines: diff --git a/source3/Makefile.in b/source3/Makefile.in index 8304981..1ce0ce9 100644 --- a/source3/Makefile.in +++ b/source3/Makefile.in @@ -985,6 +985,14 @@ IDMAP_HASH_OBJ = \ winbindd/idmap_hash/idmap_hash.o \ winbindd/idmap_hash/mapfile.o +IDMAP_ADEX_OBJ = \ + winbindd/idmap_adex/idmap_adex.o \ + winbindd/idmap_adex/cell_util.o \ + winbindd/idmap_adex/likewise_cell.o \ + winbindd/idmap_adex/provider_unified.o \ + winbindd/idmap_adex/gc_util.o \ + winbindd/idmap_adex/domain_util.o + WINBINDD_OBJ1 = \ winbindd/winbindd.o \ winbindd/winbindd_user.o \ @@ -2218,6 +2226,10 @@ bin/[EMAIL PROTECTED]@: $(BINARY_PREREQS) $(IDMAP_HASH_OBJ) @echo "Building plugin $@" @$(SHLD_MODULE) $(IDMAP_HASH_OBJ) +bin/[EMAIL PROTECTED]@: $(BINARY_PREREQS) $(IDMAP_ADEX_OBJ) + @echo "Building plugin $@" + @$(SHLD_MODULE) $(IDMAP_ADEX_OBJ) + bin/[EMAIL PROTECTED]@: $(BINARY_PREREQS) winbindd/idmap_tdb2.o @echo "Building plugin $@" @$(SHLD_MODULE) winbindd/idmap_tdb2.o diff --git a/source3/configure.in b/source3/configure.in index 640afc4..d1000d9 100644 --- a/source3/configure.in +++ b/source3/configure.in @@ -6058,6 +6058,7 @@ SMB_MODULE(idmap_nss, winbindd/idmap_nss.o, "bin/nss.$SHLIBEXT", IDMAP) SMB_MODULE(idmap_rid, winbindd/idmap_rid.o, "bin/rid.$SHLIBEXT", IDMAP) SMB_MODULE(idmap_ad, winbindd/idmap_ad.o, "bin/ad.$SHLIBEXT", IDMAP) SMB_MODULE(idmap_hash, \$(IDMAP_HASH_OBJ), "bin/hash.$SHLIBEXT", IDMAP) +SMB_MODULE(idmap_adex, \$(IDMAP_ADEX_OBJ), "bin/adex.$SHLIBEXT", IDMAP) SMB_SUBSYSTEM(IDMAP, winbindd/idmap.o) SMB_MODULE(nss_info_template, winbindd/nss_info_template.o, "bin/template.$SHLIBEXT", NSS_INFO) diff --git a/source3/winbindd/idmap_adex/cell_util.c b/source3/winbindd/idmap_adex/cell_util.c new file mode 100644 index 0000000..f5c08a0 --- /dev/null +++ b/source3/winbindd/idmap_adex/cell_util.c @@ -0,0 +1,292 @@ +/* + * idmap_adex: Support for AD Forests + * + * Copyright (C) Gerald (Jerry) Carter 2006-2008 + * + * 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 2 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.
