Eve Maler suggested an alternative shibboleth for distinguishing the SAML community from others - namely the pronunciation of 'PAOS'.
Eve points out that the shibboleth I had proposed - 'back-channel' - was originally introduced by Liberty and so it doesn't serve to distinguish SAML from Liberty. While not ignoring the differences, I actually think of Liberty as part of the 'SAML tribe' - fundamental as SAML is to the LAP architecture.
Eve postulates that:
in SAML discussions, this is usually pronounced “pay-oss". But in Liberty meetings, it’s pronounced “paah-ose” – by some of the same people.
I'm at a Liberty meeting right now so I'm going to start keeping track of how people say 'paos' , results to come.
