Neplatné heslo uživatele při přihlašování

Zdravím

bojuju s jednoduchou databází uživatelů pro kterou jsem si vytvořil dočasný formulář na registraci + přihlášení. Problém je, že po přidání uživatele do databáze přes registrační formulář se na něj nelze přihlásit, jelikož to vyhodí error neplatné heslo (které určitě zadávám stejné jako při registraci).
Využívám třídy Usermanager/SignPresenter/SignFormfactory do kterých jsem přidal pár metod, co jsem potřeboval. Děkuji za odpověď.

UserManager
