JDBC Realm authentication with single table - glassfish

Question

I tried to make jdbc realm authentication with single table, but it always redirect me to loginerror page.
Here is my settings:
Table (korisnici):
idkorisnika
korIme (it is username)
sifra (it is password)
tipKor (it is role)
Role type's are: admin, radnik and klijent
Password in database is hashed as SHA-256
