Hi, If a user's login name is changed (yes this is possible in the user manager) the user manager call deleteUser() with the old username and createUser() with the new one. If you don't set a new password at the same time the auth backend gets an already encrypted password and encrypt it again -> The new user can't never login again. This patch adds support for modifyUser() to change the username so that the user manager don't need to call deleteUser() and createUser() anymore. The bug described above was fixed then. To let this patch unfold its full power another patch for the user manager is needed. Unfortunately my darcs can't connect to Cris' user manager repository annymore, so that I can't post the missing patch. Chris, what's happend to your repo? Best Regards Matthias
