When I configure my url parameters to by lower case and srbac inserts actions in case sensitive way, for example, itemRegisterAdmin
So if I check that my url must by lower case, than Yii::base function checkAccess has lower cased action itemregisteradmin and selects from database srbac saved action itemRegisterAdmin, than it compares and the rezult is ‘itemregisteradmin’ === ‘itemRegisterAdmin’ and checkAccess function returns false.
So in this way I suggest to rewrite checkAcces function in secont Yii realize and for solving this problem, it can be rewriten in srbac module.
