I have Unity 5.0 Build 5.0(1) and bulk edit 4.0 build 115.
When I use the password tab to reset a range of users passwords they are not changed correctly. I have set a users password to a default of 2222 using SA and verified it was correct by logging in via the TUI. I then ran the bulk edit tool and changed this users password to 3333. Now neither password works.
