A Progress Report on the Migration to Shibboleth IdP V3

You’ve probably heard by now that Shibboleth IdP V2 reached end-of-life on July 31, 2016. Going forward, no bug fixes—not even security-related bug fixes—will be issued by the Shibboleth Project. In other words, Shibboleth IdP V2 is unsupported software.

Shibboleth IdP operators in the InCommon federation and other federations around the world are actively Upgrading to Shibboleth IdP V3. This article summarizes the progress of that effort over the last six (6) months.

All statistics in this article were compiled on January 2, 2017.

Here are some interesting facts:

  • Nearly 90% of the IdPs registered by InCommon are Shibboleth IdPs

  • Three-fourths of the world’s IdP deployments are based on the Shibboleth software

  • Four federations deploy three-fourths of the world’s Shibboleth IdPs

  • The same four federations account for three-fourths of the Shibboleth IdP V3 deployments worldwide

  • More than half (23/40) of the world’s federations each deploy fewer than three (3) Shibboleth IdPs

  • Fifteen federations deploy no Shibboleth IdPs whatsoever

Now let’s take a look at global migration activity by examining eduGAIN metadata.

Shibboleth IdPs in eduGAIN Metadata

Four federations deploy three-fourths of the world’s Shibboleth IdPs:
