Hi,
I found the time to test my previous patch and improve it.
This email has the new resulting patch attached.
How does it work?
1. Pootle tries to authenticate the user using the database and if it fails,
2. Pootle tries to authenticate the user using the users.prefs file
and if it succeeds
3. A new user is added to the database with the same login data
4. Next time this same user tries to login he will be authenticated
using the database
Regards,
Flávio Martins
