Refreshing session in SN without logout

Very common business requirement is to update users roles dynamically without asking them to re-login and also profile pictures.

This problem is pending the fix related to PRB1360299/KB0951799 because the photo ref which is being used to get the image from the cache will now get deleted. Just run a following code in the background script, this is a kinf of usefull feature for developers.

GlideSecurityManager.get().setUser(gs.getUser());

gs.getSession().loadUserByID(gs.getUser().getID());

var rollback = new GlideRollback();
 var modCount = 0;
 
 var sys_user = new GlideRecord('sys_user');
 
 var userId = "--put the sysId here--";
 if (sys_user.get(userId )) {
  modCount = parseInt(sys_user.sys_mod_count.toString(), 10);
 
  rollback.toVersion(sys_user, modCount - 1);
  gs.info(sys_user.last_name.toString());
 
  rollback.toVersion(sys_user, modCount - 2);
  gs.info(sys_user.last_name.toString());
 }
