How do I go about changing an admin account password in the database in Magento 1.14 (enterprise)
Is it sha(256) with a 32 character salt
You will find that you actually don't need to add the salt to reset the Magento EE passwords. A simple MD5 reset will work from my experience:
UPDATE `admin_user` SET `password` = MD5('NEWPASSWORD') WHERE `username` = 'ADMINUSERNAME';
