I was at France Telecom R&D in a team working in authentication, and remember clearly admiring the work of entre'ouvert. At the time, I tested Lasso [0] on my own computer but never used it in real projects. Colleagues also found it very interesting.
I tested many similar open source framework, such as SimpleSamlPhP which we used (and give credit) in a European research project.
There was also a US company making an authentication framework in Java.

That's as far as possible to the reality. The French state is constantly broke, for example it argued of IT problems to delay military staff pay by several month and delay providers payment by a year (Louvois), while making a law that forbids the private sector to delay payments more than two months!
It asked to Orange to work for free on many topics and it probably did the same at other big companies.
Never do business with the French state!
