[OpenID] The Various Methods For "user at domain.com" Style Identifiers

[Peter Williams]

First time I've heard of an entity other than an OP performing the  directed identity "protocol"

...If an email address domain name supports directed identity

...redirects the user to the OP,

Is this a standardized flow in openid?

If such a flow is  not laid out in the spec, it doesn't have the (relative) IP protections of other finalized materials.

This comes up periodically.  The last time it did, it ended with: "it already works, via directed identity."  If an email address domain name supports directed identity, then a user can type his/her own email address, and it (becoming equivalent to just the domain name of that email address) redirects the user to the OP, where the identifier can be decided on and the assertion sent back to the RP.

convention,  so that when someone types joe at example.com<mailto:joe at example.com> into the
openID slot the identity widget offers joe a choice of
http://smtp.openid.tipjar.com/example.com/joe and a few other similar
services suggesting the rewritten versions.
