Login form error 401

Hello,

I read

and watched

however, I can not solve my problem.

I registered my test accounts, one is without hash (call A), the other one is with hash and salt (call B).

and server action for login, I set like this.

Then, neither A nor B can login.

When I remove hash setting from login properties, only A can login but B can not do it.

Please let me know how to solve this one.

Thanks,
