Well, I’ve finally gone ahead and posted a Zend Framework component proposal: Zend_Auth_Adapter_Flexible. It’s the same idea I wrote up in my last post, but with a few key modifications; I thought I’d take a minute or two to discuss those modifications here.
First, the new proposal does not involve a user model; it pulls authentication credentials directly out of the strategy class’s Zend_Form instance. This change is mainly due to the framework’s lack of a formalized model layer…plus, it reduces the complexity of the idea, which is always a good thing.
Second (on a related note), the new component does not make any attempt to standardize what type of identity gets stored by Zend_Auth. Since authentication strategies will be written on an ad-hoc application-by-application basis, I figure that developers will want to take their own approach to this.
Third, the new proposal will hopefully take advantage of Zend_Navigation to automatically generate a list of links to available authentication strategies. I’m really not sure of how that would happen yet, since the plugin loader class doesn’t have any methods for retrieving all available class names—but if the community thinks it’s a good idea, there will likely be suggestions on how to take care of it.
I did keep the basic class name structure intact, which may or may not be a good thing. Zend_Auth_Strategy_Interface would require a new namespace under Zend_Auth, and I don’t know that I have a good justification for that. I do know that authentication strategies need to be distinguished from regular authentication adapters, since they do more things and have more dependencies.
So there you have it—my very first Zend Framework proposal. If you’re a Zend Framework developer and what I’ve described sounds interesting to you, please go take a look (and leave comments)!
