#43 Error: OpenID assertion failed: Server denied check_authenti

[Jim Phelps]

I have installed the latest version of the plugin (0.86) in Wordpress (2.1.3). I get the following error when I try to bind my OpenID with my user account in Wordpress:

Error: OpenID assertion failed: Server denied check_authentication

The plugin appears to have installed and configured correctly.

My OpenID works on your test site.

Here is the text from the plugin options report:

I updated to the latest SVN version (Rev 93 for MU) and I still get the error. I have used my OpenID (from protectnetwork.org) successfully on other sites so I know that it isn't a provider issue.
