error code lets you know what the authentication error is (invalid username, invalid password, etc.). Error code 0 means no error. Check the place where you use identity and call its authenticate() method, you will see why.

I agree with the OP, the name ‘errorCode’ is not good, and it’s exposing implementation detail – should it not be protected?

I think the whole stack of:

[list=1]

[*] CBaseUserIdentity extends CComponent implements IUserIdentity

[*] CUserIdentity extends CBaseUserIdentity

[*] UserIdentity extends CUserIdentity

[/list]

could do with a refactor, personally. As far as I can tell, beyond authentication, anything else should reside with Yii::app()->user. In fact, can’t you just ignore the above stack and just pass Yii::app()->user->login() your own object that implements IUserIdentity?
