I have courseware that students pay for through a Paypal account. Paypal takes payment and generates usernames/passwords to access the courseware. But, since I switched to Dreamhost from my old server, the usernames/passwords do not write to a password file, which means the passwords don't work. I can add the usernames/passwords manually through Htaccess/WebDav but it would be better to have these logged automatically. Is there a way of making it so? Thanks!
