[keycloak-dev] refactored admin reset email and required actions

Admin console can send a reset password email to the user. Originally it just executed update password. I changed this so that it sets an Update Password required action on the User. The email link click runs all required actions set for the user, then displays a message that the Account has been updated. When I get back, I'm also going to change the admin console behavior and look too. Instead of a "Reset Password Email" button on Credentials tab, there will be a button next to the Required Actions selection box on user detail, something like "Email Required Actions" (I need a better name). Clicking on this button will send an email to user "Your adminstrator has requested that you update and/or reset some of your account settings. Please click the link below to perform these actions." We do it this way because there may be multiple credentials the admin wants the user to reset. These credentials may be custom authenticators. Also I refactored the CONFIG_TOTP, UPDATE_PROFILE, and UPDATE_PASSWORD required actions. They are now fully encapsulated under the required actions SPI and are not hardcoded with any special cases. I still need to refactor verify email. Ran out of time. Finally, I need to add a check to user-initiated Reset Credentials. I haven't put back in the cookie check to make sure not to log in the user if its not the same browser. -- Bill Burke JBoss, a division of Red Hat http://bill.burkecentral.com
