I'd like to share with both the dvn-auth list and the larger Google Group a new "pluggable authentication" design we have come up with for Dataverse 4.0. We've tried to incorporate as much feedback as we could in the design but could use your help in reviewing it to make sure we haven't missed anything: https://github.com/IQSS/dataverse/blob/master/doc/Architecture/auth.md At a high level, we hear you loud and clear that you want Shibboleth support. Some groups seem interested in contributing code for LDAP and OAuth. We plan to continue to support IP groups. We'd like to introduce API keys. We're not picky about how you give us feedback on the pluggable auth design. You can comment directly on the commits on GitHub. Or reply to this email. Or hit us up on IRC. We'd like to start coding this up soon. :) Thanks! Phil -- Philip Durbin Software Developer for http://dataverse.org http://www.iq.harvard.edu/people/philip-durbin
