Just a short update:
from 5th till the 7th of may I will attend the European Identity Conference in Munich. I will be presenting a few thoughts about Access Control in the Cloud, covering Claims Based Access Control and Identity Provisioning (in the fog...). My talk will follow Martin Kuppinger's in Stuart Boardman's forum. I'm looking forward to meeting lots of experts in the field.
Munich, twice within a year: last year I presented a similar story at The Open Group's architecture practitioners conference. I like this city :)
