  1. Overview of our components:glexec, lcas, lcmaps and job repository Gerben Venekamp & Oscar Koeroo

  2. About • Our dependencies • And what functionality are they fulfilling? • Which problems can be foreseen? • What are your "problem" dependencies? • What would you like to replace them with? • Any other comments on this restructuring. Overview of our components:

  3. Our dependencies (1) • LCAS • OpenSSL lib • Globus lib • Interface from edg-gatekeeper and edg-gridftpd to the framework • Makes use of some handy Globus functions • LCAS-VOMS plugin • voms_api • Gridsite-core • For GACL and later XACML support Overview of our components:

  4. Our dependencies (1) • LCMAPS • OpenSSL lib • Globus lib • Interface from edg-gatekeeper and edg-gridftpd to the framework • Makes use of some handy Globus functions • LCMAPS VOMS plugins • voms_api • LCMAPS JobRep plugin • Jobrepository-api • Job Repository API • unixODBC • LCMAPS AFS plugin • Some AFS lib • LCMAPS LDAP enforcement plugin • LDAP lib Overview of our components:

  5. Our dependencies (2) • Glexec • OpenSSL • LCAS • LCMAPS Overview of our components:

  6. Problem dependencies • LCAS and LCMAPS have interfaces to them which use Globus specific calls • Perfectly fine in GT2.4 • Seems to be fine in GT4.x (pre WS) • Tests showed no problems • Real life experiences on production environments are unknown • The inherent dependency through VOMS to Globus • We’re still using the Globus based VOMS api • We can do without the Globus lib by leveraging OpenSSL functions directly • This will make it easier to use LCAS and LCMAPS from other components • Note: Our current ‘No Globus’ build is actually a “No (inherented) OpenSSL” • This means: no OpenSSL, no Globus and no VOMS • Only in the form of strings of each of the credentials Overview of our components:

  7. What would you like to replace them with? • LCAS and LCMAPS have interfaces to them which use Globus specific calls • Replace with commonly (> RHEL 3.0) deployed OpenSSL functions • The inherent dependency through VOMS to Globus • Switch to the “No Globus VOMS API” Overview of our components:
