[openstack-dev] [keystone] long term fate of UUID token?

There's still appears to be considerable demand for UUID tokens,
considering their simplicity relative to PKI tokens (no additional setup
required, convenient length for copy/pasting around). There are also
trade-offs when deciding between UUID and PKI tokens (e.g. network chatter
vs CPU time, revocation behavior, etc).

I don't think we can consider UUID tokens deprecated yet, although I would
certainly encourage everyone using them to take a hard look at PKI. I
suspect that most of the deployers that tried PKI but stuck with UUID
tokens did so because they ran into configuration / debugging issues with
PKI tokens, and keeping UUID was the easiest solution. Hopefully we've
resolved a lot of those bugs, so I'd be interested in hearing any continued
reasoning for not making the switch.
