Federation Web Site

• We’re seeing about 1500 page views per
  day at present: significant use
• That has been pretty stable for 11 months,
  although federation itself has grown
• Perhaps people use the site when they’re
  joining, but not afterwards?

                 5
Membership
•   Many members have both IdP and SP entities

    •   may be for testing or for collaboration

•   Half of members have no participation

    •   Good awareness, bad deployment?

    •   Planning on gateway use only?

•   “Gateway members” beginning to show up

Software
• Shibboleth dominates
 • Almost all 1.3: only 3×1.2, 2×2.0
• If other software supported large scale
  federation, more people might use it.
• Need to determine how much to let
  technical holes in other software hold us
  back
