  1. Gridification progress report For gridification: Martijn Steenbakkers hep-proj-grid-fabric-gridify@cern.ch

  2. Gridification Architecture

  3. Authentication control flow EDG gatekeeper NOW (EDG1.2), EDG 1.3 EDG1.4, EDG2.x Gatekeeper Gatekeeper LCAS config TLS auth TLS auth ACL Id timeslot Yes/no LCAS (so) LCAS client gridmap LCMAPS clnt LCMAPS Id assist_gridmap config apply creds * credlist Jobmanager-* Jobmanager-* role2uid role2afs * And store in job repository

  4. LCAS 1.0 (EDG release 1.2) • First prototype: shared object (lcas.mod) • Dynamic library calls from edg-gatekeeper • 3 static authorization modules: • Allowed users (grid-mapfile or allowed_users.db) • Banned users (ban_users.db) • Available timeslots (timeslots.db) • LCFG object obj-lcas installs authorization databases • No plug-ins supported yet • Documentation: http://www.dutchgrid.nl/DataGrid/wp4/lcas/

  5. Integration tests • Linked dynamically instead of statically • Development testbed: occasional crashes (hard to reproduce) • Bugzilla bugs: 431, 471 • Memory corruption and memory leaks in Globus code (found a.o. with insure++) • New patch available: edg-gatekeeper-2.0.3-21d • ATF discussion last week: Rewrite gatekeeper ?

  6. LCAS 1.1 (EDG release 1.3) • Shared object with the 3 authorization modules • Plug-in framework added (based on dynamic library calls) • List of plug-ins to be loaded in lcas.db • Example plug-in: lcas_plugin_example.c • Plug-in has to provide the following interfaces: • int plugin_initialize(int argc, char ** argv) • int plugin_confirm_authorization( lcas_request_t request, lcas_cred_id_t user_cred) • int plugin_terminate() • Documentation soon available • Please develop plug-ins (ACL, accounting, quota checks)

  7. Future • LCMAPS local credentials • Library implementation of credential generation plug-in framework • Replace gridmap(dir), but keep functionality • Logical place to add role support • EDG release 1.4 (?) • AFS/Kerberos support: EDG release 2.x • LCAS 2.0: • first prototype AAA server with simple policy language • EDG release 2.0 (?) • Additional modifications to gatekeeper required • error&status handling: Getting a useful message to the user • Rewrite partially ? • Other components (job repository, FLIDS, FABNAT) > EDG 2.x
