WordPress MU

Trying to access to the login screen takes a very very long time, and then there is always an error above the login fields,

ERROR: Wrong username / password combination.

This will happen when accessing /wp-admin/ or wp-login.php, and even on a browser with no cookies/history/sessions.

Has anyone experienced a similar issue? It wasnt always the case, but after one of the recent core updates, I started to get this slow-down cropping up.

Let me add, after successfully logging in, everything runs fine. This is a problem when you dont have a successful login session currently established.

Check out the default htaccess.dist and wp-config-sample.php. Make sure in your upgrades you move over any extra bits, which is quite possible if you've upgraded from way bakc. The .htacess and wp-config don't get upgraded with any new lines.

I reviewed the files, and they seem to match, except:

Some time ago I upgraded from 2.6 to 2.7, so I followed the instructions on http://codex.wordpress.org/Upgrading_WPMU for it.

The part in MY config that doesnt match the new config-sample is the following (but I was instructed to insert them)

define('SITECOOKIEPATH', '');
define('COOKIEPATH', '');
define('COOKIE_DOMAIN', '');
define('ADMIN_COOKIE_PATH', '/');

...and I have two extra keys/salts that are no longer in the wp-config.. (not sure where these came from)

define('SECRET_KEY', ''); // Change these to unique phrases.
define('SECRET_SALT', '');

Should I remove these?

Thanks!

..well, as a test I cleared out those two sets of items in the log, and the issue still occurs.

When not logged in, and attempting to access wp-login or wp-admin, I get a very long delay, followed by the page loading with the error, "ERROR: Wrong username / password combination."

well, nevermind.

Turns out it was a bug in my LDAP authentication plugin that has been patched.

The problem has now gone away.

Good to know your issue is resolved.

Thanks 'kingkong954'.

I've spent an hour trying to figure out why I'm suddenly locked of of my WPMU sites, and after seeing your post, I upgraded my WPMU-LDAP plugin and voila. I'm in!

Panic attack over!
