From 16cc94c7c4bf757a322f6605da33230f34b7a41e Mon Sep 17 00:00:00 2001 From: Sumit Bose Date: Wed, 30 Nov 2011 13:29:10 +0100 Subject: Add external domain extop DS plugin This extop can be used by clients of the IPA domain, e.g. sssd, to retrieve data from trusted external domains. It can be used e.g. to map Windows SIDs to user or groups names and back. --- daemons/configure.ac | 19 +- daemons/ipa-slapi-plugins/Makefile.am | 1 + .../ipa-slapi-plugins/ipa-extdom-extop/Makefile.am | 74 +++ daemons/ipa-slapi-plugins/ipa-extdom-extop/README | 0 .../ipa-extdom-extop/ipa-extdom-extop-conf.ldif | 16 + .../ipa-extdom-extop/ipa_extdom.h | 154 +++++++ .../ipa-extdom-extop/ipa_extdom_common.c | 498 +++++++++++++++++++++ .../ipa-extdom-extop/ipa_extdom_extop.c | 234 ++++++++++ .../ipa-extdom-extop/ipa_extdom_tests.c | 203 +++++++++ freeipa.spec.in | 7 + ipaserver/install/adtrustinstance.py | 14 +- ipaserver/install/service.py | 3 +- 12 files changed, 1220 insertions(+), 3 deletions(-) create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/Makefile.am create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/README create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/ipa-extdom-extop-conf.ldif create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/ipa_extdom.h create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/ipa_extdom_common.c create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/ipa_extdom_extop.c create mode 100644 daemons/ipa-slapi-plugins/ipa-extdom-extop/ipa_extdom_tests.c diff --git a/daemons/configure.ac b/daemons/configure.ac index 547c907f3..8f0268835 100644 --- a/daemons/configure.ac +++ b/daemons/configure.ac @@ -237,8 +237,19 @@ PKG_CHECK_MODULES([NDRPAC], [ndr_krb5pac]) PKG_CHECK_MODULES([NDRNBT], [ndr_nbt]) PKG_CHECK_MODULES([NDR], [ndr]) PKG_CHECK_MODULES([SAMBAUTIL], [samba-util]) -SAMBA40EXTRA_LIBPATH="-L`$PKG_CONFIG --variable=libdir samba-util`/samba" +SAMBA40EXTRA_LIBPATH="-L`$PKG_CONFIG --variable=libdir samba-util`/samba -Wl,-rpath=`$PKG_CONFIG --variable=libdir samba-util`/samba" AC_SUBST(SAMBA40EXTRA_LIBPATH) +AC_CHECK_HEADERS([samba-4.0/wbclient.h], + , + [AC_MSG_ERROR([samba-4.0/wbclient.h not found])], + [#include + #include ]) +AC_CHECK_LIB([wbclient], + [wbcLookupSid], + [WBCLIENT_LIBS="$SAMBA40EXTRA_LIBPATH -lwbclient"], + [AC_MSG_ERROR([libwbclient does not have wbcLookupSid])], + [$SAMBA40EXTRA_LIBPATH]) +AC_SUBST(WBCLIENT_LIBS) dnl --------------------------------------------------------------------------- dnl -
