I have a moodle installation. I read in the manuals that moodle uses MD5. So I set it so from the configuration of External DB Authentication. But I get an "invalid password" error message.
If I try to change the username / password column names from the configuration, I get an error that could not find the right column.
If I try and give an unknown username, I get an "unknown user" error message.
It seems that it communicates with moodle user database, but it can't resolve the passwords!
