I am using Grails Spring Security Core with Persistent Logins. Thus, the login information of a user are stored in my database. My problem is the following case:
A user is logged in and his username will change from x to y. This means I have to reauthenticate the user with:
springSecurityService.reauthenticate y
rememberMeServices.loginSuccess(request, response, springSecurityService.authentication)
In my database the username for the persistent token remains x. How can I set a new entry for a persistent token with the new username y?
You should find the existing database entry for the user. This can be done by username. Then you can set a new database entry as a persistent token with rememberMeServices.loginSuccess. Finally, you have to reauthenticate your user.
