[Plugin: WP-OpenID] Problem with identity URL on a single user blog

Hi,
I am trying to implement wp-openid v.3.0 provider features in my single-user blog. Running WP 2.6.2.
In the OpenID Provider Options in admin panel it says that the Blog Owner will be able to use the blog address, so it is set to my ‘admin’ account (the only account on the blog).
But somehow I cannot use my URL: https://www.craneway.ru/ to login at other OpenID enabled sites.
I can only use https://www.craneway.ru/author/admin/ (and it works just fine).
It looks like this second URL is outputted in the xrds generated file, and it appears to be the url for ‘openid.delegate’ and ‘openid2.local_id’ in the blog header markup if I call this url directly in the browser.
There is no such markup in the header of the blog if I call https://www.craneway.ru/

The blog is installed on a addon domain. Can’t understand what is wrong. Any ideas of what should be changed?
