Confusing message while logging in using openid on istylr.com

The XRDS served by c-i-p is wrong for delegated identities, yet it is linked from https://launchpad.net/~USER. It has no openid:Delegate elements, so XRDS-capable consumers attempt to authenticate to https://login.launchpad.net/+openid with the original URL, not https://login.launchpad.net/+id/SOMETHING.

Adding <openid:Delegate>https://login.launchpad.net/+id/SOMETHING</openid:Delegate> to the produced XRDS makes everybody happy again.

I really think this is more than 'low' priority: you can't interoperate with the openid world properly at the moment.

Neither have you ever been able to. To the best of my knowledge, this isn't a regression but functionality which has never worked. It's also trivially easy to work around by creating a regular account on a site which doesn't work so qualifies as a minor annoyance at worst. If we'd had more user reports or the bug hadn't just sat in an untended state for the past 7 months without any activity then I'd consider making it a medium priority. As it is, I think 'low' is reasonable.

The produced XRDS has changed in the last 3 months -- the last version to live in the Launchpad tree only provided 2.0 information, not 1.0 and 1.1. Maybe that is relevant.

Note that istylr.com has bigger problems. My fix breaks their OpenID consumer badly (yielding a blank page). I don't think this is the same bug.

Thanks for the additional information.

Its a regression; a month or so ago it worked.

Anyhow, I see the bugs have been de-dupped, so I'll follow up on my
specific bug.

Looks like this was fixed some time ago. Going to my xrds file, I get:
