> some of my user trying to login Mikrotik but they cant first time.. You may find that it will be easier for people to help you if you provide specific details about the problems you are having and what you've done in an attempt to fix the problems.
You should start by doing Internet searches to see if someone else had the same problem(s) and what was done to fix it. If you can't find anything relevant, post the debug output of a failure. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
