Created 2 years ago by zeroByteHow-tos0 comments – viewed 13,438 times – version 1.1
This HowTo assumes that you have a smattering of ACL in general and of how the acl-extension works basically. It will introduce you into the abstract and give you a hint on how to use Business-Rules. If you have in-depth questions, please refer to the extension documentation. Using ACL in an RBAC-manner cannot and should never obscure the fact that the underlying system is still ACL-based. In fact, the Business-Rules are just another layer in the permission-check plan.

Created 2 years ago by nkdHow-tos8 comments – viewed 6,602 times – ( +2 ) – version 1.1
I installed phpseclib because I needed to do some AES encryption in my project. After all the hassle of installing php lib, I found out that Yii already has a security module (securityManager). I finally decided to keep using phpseclib because it has one big advantage over Yii securityManager module, it does not requite mcrypt to be installed in the phpserver!
