1. Attribute-based Authentication for Gateways Jim Basney Terry Fleury Stuart Martin JP Navarro Tom Scavo Jon Siwek Von Welch Nancy Wilkins-Diehr

2. Gateway Objectives for PY4 and 5 TeraGrid integration will be straightforward for new and existing gateway developers There will be a set of easy to discover general services provided by and for Gateways The targeted support program will be well- organized We will be able to routinely count end gateway users, who will total 25% of total TeraGrid users There will be a funded cross-directorate gateway program at the NSF Presented December, 2007

3. We will be able to routinely count end gateway users, who will total 25% of total TeraGrid users A unique identifier for each end gateway user per community account must exist in TGCDB Gateways will need to transmit and TGCDB will need to receive this additional identifier through any job submission mechanism Attribute-based authentication in production and easy to use Presented December, 2007

4. How will we meet those goals? Attribute-based authentication –In our case, GridShib for Globus –Fantastic documentation and assistance Thanks Jim Basney, Tom Scavo, Terry Fleury –http://www.teragridforum.org/mediawiki/index.php?title =Science_Gateway_Credential_with_Attributeshttp://www.teragridforum.org/mediawiki/index.php?title =Science_Gateway_Credential_with_Attributes From the April, 2009 TeraGrid review panel –“The TG has stated the goal of switching to an attribute- based authentication mechanism for all Gateways by September of 2009. The panel recommends that every effort be made to complete this work on schedule.”

5. How will this be made available at RP sites? science-gateway CTSS kit, which includes commsh –NCSA-developed, PSC-enhanced tool to restrict community accounts –http://teragridforum.org/mediawiki/index.php?title=Community_Shel lhttp://teragridforum.org/mediawiki/index.php?title=Community_Shel l GridShib for Globus Toolkit –NCSA-developed tool to collect, process, store and log attributes Future TG-specific efforts will store these in the TGCDB –http://gridshib.globus.org/http://gridshib.globus.org/ Installation instructions –http://software.teragrid.org/pacman/ctss4/ctss-science-gateway- registration/README.install

6. Ambitious, but achievable goal By September, 2009 all jobs submitted by community accounts will include attributes with unique user identifiers to be stored in the TGCDB Next steps –RP testing through Feb 2009 –Globus Toolkit 4.0.9 released Feb 2009 –Capability Kit V2 released Mar 2009 –Production installations of Capability Kit V2 –6-month gateway transition – March through August News postings, education process, log analysis to identify who still needs to make the switch, lots of support –Big party in September! Presented January, 2009

7. What’s happened between January and now? One word - GRAM5 –http://dev.globus.org/wiki/GRAM/GRAM5http://dev.globus.org/wiki/GRAM/GRAM5 Two words – party delayed GRAM5 replacing GRAM2 (aka pre-WS GRAM) –AAAA changes incorporated only in GRAM5 since GRAM2 is being retired –ssh support only in GRAM5 So, now we must wait for a production version of GRAM5 before we have attribute support for pre- WS GRAM and ssh

8. GRAM5 timeline Alpha versions installed –QueenBee and Abe, thanks! Sept 15, 2009 news posted about GRAM5 availability for testing –http://news.teragrid.org/view-item.php?item=4266http://news.teragrid.org/view-item.php?item=4266 Steps to TeraGrid availability –Globus staff completes GT 5.0.0 (December 2009) –VDT patching and verification (Alain Roy, 1-2 wks) –GIG staff completes TeraGrid packaging (1-2 wks) –ADs plan TG-wide deployment NOS (and RPs), UFP, software-wg, user services, gateways

9. Additional info Also need site-local accounting scripts to send attributes to TGCDB –RP accounting staff Who’s already done? –NICS has installed GT4 with attributes Thank you Victor and Rick Thank you Matthew at NCAR for attribute support in AMP gateway which is running on Kraken –Early “attribute-enhanced” GT4 install experiences A novice RP should set aside maybe 1 week to do the entire install (being very generous), and an expert GRAM4 admin should be able to do the entire install in 2 days Side note –Jon Siwek replaces Tom Scavo supporting this effort at NCSA Thanks for replacing such a key team member promptly
