iFolder 2.1.6/NE6.5 SP4

I created several new users to iFolder. When I try to login either at the
client or the web interface it tells me it is the wrong password. Users
already using iFolder are working just fine. I know the passwords are
correct as each can login to the network fine, but not into iFolder client
or web interface.
Everything on the monitor page looks fine, must be running ok if other users
can sync.
Any help....
