From 42b324e99ca943e6bed560e3021219d513672ca2 Mon Sep 17 00:00:00 2001 From: Adam Dickmeiss Date: Wed, 15 Aug 2012 15:39:28 +0200 Subject: [PATCH] zoom: authentication via Torus Enabled by new configuration setting: auth_url . If this is defined, the zoom module will contact Torus for auth/IP lookup and that will define realm to be used in session (IP not done yet). --- etc/config-zoom.xml | 11 +++- src/filter_zoom.cpp | 121 ++++++++++++++++++++++++++++++++++++++++++-- xml/schema/filter_zoom.rnc | 1 + 3 files changed, 127 insertions(+), 6 deletions(-) diff --git a/etc/config-zoom.xml b/etc/config-zoom.xml index 0801d41..9a6b722 100644 --- a/etc/config-zoom.xml +++ b/etc/config-zoom.xml @@ -9,7 +9,8 @@ + + + + @@ -205,10 +212,12 @@ + B diff --git a/src/filter_zoom.cpp b/src/filter_zoom.cpp index ae84b7b..bf12680 100644 --- a/src/filter_zoom.cpp +++ b/src/filter_zoom.cpp @@ -119,11 +119,15 @@ namespace metaproxy_1 { Impl *m_p; bool m_is_virtual; bool m_in_use; + std::string session_realm; yazpp_1::GDU m_init_gdu; BackendPtr m_backend; void handle_package(mp::Package &package); void handle_search(mp::Package &package); + void auth(mp::Package &package, Z_InitRequest *req, + int *error, char **addinfo, ODR odr); + BackendPtr explain_search(mp::Package &package, std::string &database, int *error, @@ -210,6 +214,7 @@ namespace metaproxy_1 { boost::condition m_cond_session_ready; std::string torus_searchable_url; std::string torus_content_url; + std::string torus_auth_url; std::string default_realm; std::map fieldmap; std::string xsldir; @@ -674,6 +679,8 @@ void yf::Zoom::Impl::configure(const xmlNode *ptr, bool test_only, torus_searchable_url = mp::xml::get_text(attr->children); else if (!strcmp((const char *) attr->name, "content_url")) torus_content_url = mp::xml::get_text(attr->children); + else if (!strcmp((const char *) attr->name, "auth_url")) + torus_auth_url = mp::xml::get_text(attr->children); else if (!strcmp((const char *) attr->name, "realm")) default_realm = mp::xml::get_text(attr->children); else if (!strcmp((const char *) attr->name, "xsldir")) @@ -1018,7 +1025,9 @@ yf::Zoom::BackendPtr yf::Zoom::Frontend::get_backend_from_databases( std::string authentication; std::string content_authentication; std::string content_proxy; - std::string realm = m_p->default_realm; + std::string realm = session_realm; + if (realm.length() == 0) + realm = m_p->default_realm; const char *param_user = 0; const char *param_password = 0; @@ -1098,9 +1107,9 @@ yf::Zoom::BackendPtr yf::Zoom::Frontend::get_backend_from_databases( out_values[no_out_args++] = value; torus_url = m_p->torus_content_url; } - else if (!strcmp(name, "realm")) + else if (!strcmp(name, "realm") && session_realm.length() == 0) realm = value; - else if (!strcmp(name, "torus_url")) + else if (!strcmp(name, "torus_url") && session_realm.length() == 0) torus_url = value; else if (name[0] == 'x' && name[1] == '-') { @@ -2421,6 +2430,97 @@ void yf::Zoom::Frontend::handle_package(mp::Package &package) } } +void yf::Zoom::Frontend::auth(mp::Package &package, Z_InitRequest *req, + int *error, char **addinfo, ODR odr) +{ + if (m_p->torus_auth_url.length() == 0) + return; + + std::string user; + std::string password; + if (req->idAuthentication) + { + Z_IdAuthentication *auth = req->idAuthentication; + switch (auth->which) + { + case Z_IdAuthentication_open: + if (auth->u.open) + { + const char *cp = strchr(auth->u.open, '/'); + if (cp) + { + user.assign(auth->u.open, cp - auth->u.open); + password.assign(cp + 1); + } + } + break; + case Z_IdAuthentication_idPass: + if (auth->u.idPass->userId) + user.assign(auth->u.idPass->userId); + if (auth->u.idPass->password) + password.assign(auth->u.idPass->password); + break; + } + } + // need to dig out IP!!
