Authentication is such a general problem, which most websites have to implement. There are a few commercial solutions, but all lack sufficient functionality to customize the registration process. Therefore, I am looking for an open-source alternative. I am using PHP and with PostgreSQL as database, but as far as I understand one could utilize authentication solutions using other technologies and integrate them into our site in various ways. Therefore, I am looking for such solutions in any technology apart from those requiring Microsoft infrastructure...
I would prefer Open Source solution, which have already implemented the following features:
- Has password recovery procedure
- Username is the email address of the user
- Has "Remember me" functionailty (meaning that the user is logged in automatically without seeing the login page)
- email address verification
Google has gotten me nowhere on this and neither a search on this site...
