OK i figured out the usermanger does have the capabilty to allow or not allow multiple logins. This only works if your running hotspot configuration. My default when you login it checks the hotspot local database first , (the user profile). All you have to do is create mulitple Profiles on your hot-spot. You can make a profile called 1logins and have the shared users option set to 1, and another called 2logins and have that one have the shared option of 2 users. Now in the usermanager you have to tell it inthe users section what group the user is bound to. If you want that user to have multiple logins then you can put 2logins for the group name in the users section in the usermanger. If you only want 1 user to login then put 1login in the users section. Note if you assign an ip address specifically then both users cant be on at the same time becuase it will give each login that ip address. But it works for for dhcp solution for multi logins. I tested this and it does work. Im currently running radiusmanager and usermanager at my locations , i like the ease of use of usermanger , radiusmanager still has some extra features but isnt as easy to use , install or backup, Kudos to mikrotik for even introducing this usermanger. ) I understand this senario prolly wont work for eveyone , but i wanted to let people know that this can be done. So if you are running hot-spot and the usermanger is allowing multiple logins and you dont want it to then go to your winbox and hot-spot defualt user profile and change the shared users to 0 or 1 or blank.
