Blog Tutorial, authentication problem

I am simply trying to follow the blog tutorial, but not able to pass this step.

http://www.yiiframework.com/doc/blog/1.1/en/prototype.auth

Things are working before this step, but here login is not working… I think I’ve checked everything. I’ve seen a lot of other’s too with similar problems.

I’ve imported the database into my phpmyadmin.

Ok, I think I found it. The sql file available in /protected/data directory isn’t the required database.

The required database can be found in /demos/blog/protected/data
