I'm trying to set up external database enrollment on my Moodle install so that I can use some php scripts for handling user registration. The database is populating correctly, but (with Debug ADOdb turned on), when I try to log in, I get this output:
(mysqli): SELECT * FROM users WHERE username = '' AND password = 'd41d8cd98f00b204e9800998ecf8427e'
It seems that MD5 hash is equal to an empty string. Any idea what this means?
