# [Plugin: OpenID] Cannot Login

 * [17 years, 4 months ago](https://wordpress.org/support/topic/plugin-openid-cannot-login/)
 * **What steps will reproduce the problem?**
    1. Visit [http://beta.void-star.net/wp-login.php](http://beta.void-star.net/wp-login.php)
    2. Log in with another OpenID provider.
    3. Redirects to provider site, asks for confirmation.
    4. Returns to site, error message: `OpenIDloginfailed:Serverdeniedcheck_authentication`.
 * The same occurs when attempting to post comments with an OpenID or associate 
   OpenIDs with user accounts.
 * **What is the expected output? What do you see instead?**
    I expect to be able
   to authenticate with an OpenID provider, however the process fails with the error`
   OpenIDloginfailed:Serverdeniedcheck_authentication`.
 * **What version of the product are you using? On what operating system?**

 * **Please provide any additional information below.**
    The workaround [detailed here](http://code.google.com/p/diso/issues/detail?id=99)
   does not help.
 * I’ve also successfully used the plugin on a standalone, local install of WordPress,
   while it fails on other domains hosted on the same provider as [void-star.net](http://void-star.net)(
   Surpass Hosting).
 * I was originally blocking all requests made with empty browser agents via `.htaccess`(
   the error logs were throwing 403s on the verification check), however this has
   now been removed and the Apache logs look “normal”.
 * Downgrading to the previous version of the plugin didn’t help, nor has uninstalling
   it, clearing the cache, _et cetera_.
 * Authentication against a LiveJournal OpenID worked _once_, however I’ve never
   been able to replicate the behaviour.
 * Any and all assistance is appreciated.

 * Nope. 🙁
 * If I understand what’s going on correctly, that fix is for the server rather 
   than the consumer. My issue is, I think, with the consumer constantly failing
   even though it’s getting return data back from the various servers it’s hitting
   up.

 * This problem is still driving me nuts, but I’ve found two more things.
 * #1. Dumping the variables from `_httpResponseToMessage` in `Consumer.php` shows
   that it seems to run twice per OpenID request. The first returns a body with `
   assoc_handle` and so forth, the second returns with a body of `error:bad_handle`.
 * #2. Enabling `WP_DEBUG` throws a bunch of “MySQL server has gone away” errors
   during the calls to update `openid_idnetities` and `openid_associations`!
 * Hrm…

 * Whee, double-post.
 * Anyway, I think I’ve tracked it down to being a problem with the BCMath library
   used for `session_type:DH-SHA1`. The workaround is forcing the script to run 
   in “dumb mode” by changing lines 106-108 in `OpenID.php` to:
 *     ```
       //if (Auth_OpenID_getMathLib() === null) {
         Auth_OpenID_setNoMathSupport();
       //}
       ```
   
 * I still have no idea how or why this causes/fixes the issue (and it’s kinda more
   of a problem with the PHP OpenID library than the plugin), but… yeah.
 * At least I can log in now.
