Thread:Project:Support desk/SiteminderAuthPlugin is not working Mediawiki 1.18.2 upgrade

I have upgraded the MediaWiki 1.12.0 to MediaWiki 1.18.2 After the upgrade, Siteminder auto login is failing. After the initial investigation I found that the extension SiteminderAuthPlugin.php is unable to populate all mandatory fields to the user object. Hence the insert to database is failing.

Here are the Error details: A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: INSERT INTO `user` (user_id,user_name,user_password,user_newpassword,user_newpass_time,user_email,user_email_authenticated,user_real_name,user_options,user_token,user_registration,user_editcount) VALUES (NULL,'hdmauser',NULL,NULL,NULL,NULL,NULL,NULL,,,'20120518023849','0') from within function "User::addToDatabase". Database returned error "1048: Column 'user_password' cannot be null (localhost)

Please let me know if there is any solution to fix this error.
