I am running a ASP.net MVC 3 web application, and using the Membership Provider. I would like to know if its possible to allow the user (or administrator) to change an existing accounts username? I have not found a way to do this. The username is not an email address, but is validated on its uniqueness prior to my attempt at assigning the new name.
Any help would be appreciated!
The membership provider does not provide a method to update the username. You will either need to extend the membership providers UpdateUser method or directly interact with the membership tables to allow this change. However you approach this, keep in mind a few items
On update, you will need to check uniqueness of the username much like what happens when a user is created.
If the user is logged in and changes their username, you will either need to force them logout and log back in or reissue the AuthenticationTicket cookie. The reason being, if they change their username, then the authTicket cookie stored username and the actual username not longer match. If you use
HttpContext.Identity.User.Nameto query your datastore or check authorization to content, you will no longer return any results as that username no longer exists.
