can't assign password for user - file sharing

When originally setting up file sharing between to MBPs - one user needed a password to file share, while the other did not. I just wanted to speed things up while I was transferring necessary files to the new book. When I was done transferring I decided to assign a connection password for that second user - but I couldn't find how to add it.
So I deleted the name from the list & re-created the user
was prompted for a password and created one

However, the user can still connect to my book without a password??

 

anyone ?

 

thanks

I tried:
going into accounts and resetting password
(even though they never had one)
that didn't change things

so I deleted the user from 'accounts'
recreated them in file sharing (with password)

they are still able to login without a password
(also they never had 'remember keychain' selected)

 

sorry

I just restarted their machine

and connecting with a password now applies
