I'm using a custom authprovider, which is working fine so far. It uses the user table of an existing CMS to log users in into phpBB. For the first-time login, I return LOGIN_SUCCESS_CREATE_PROFILE to create the phpBB user. But what when a user changes the password or e-mail address in the CMS? How is the change propagated to the phpBB user table? Should I write the changes directly into the phpbb_users table? Unfortunately, a status like LOGIN_SUCCESS_UPDATE_PROFILE does not exist.
