Thread:Extension talk:LDAP Authentication/Intermittently receive "incorrect password" error; MediaWiki 1.18.1, LdapAuthentication 2.0b

I and other users receive an "incorrect password" ever on roughly every other attempt to log in. I upgraded the LdapAuthentication plugin, but that doesn't seem to have fixed the problem and it has made the logging data a little less clear. Formerly I was seeing "invaliddomain" errors in the log, but as of 2.0b (2012-06-21 snapshot), I get the following on the login requests that fail.

CACHES: EmptyBagOStuff[main] SqlBagOStuff[message] SqlBagOStuff[parser] session_set_cookie_params: "0", "/", "", "1", "1" LocalisationCache: using store LCStore_DB Fully initialised Connecting to localhost tadf10...

On the login requests that succeed I see a similar log but after "loading options from the database" I see a database query that inserts some tokens and some `setcookie` commands.

Running MediaWiki 1.18.1. It doesn't seem like this functionality would be effected by upgrading to 1.19. Also, I'm not aware of any configuration changes we made before this login problem started cropping up in the last few weeks.

Thanks in advance for your help!
