What you were expecting:
A <PasswordInput/> is activated with a toggle that basically handle the password field disabled prop. If toggle is not active, <PasswordInput/> is disabled, otherwise enabled. The password field has a validate prop, that defines a rule for the field. Rule is minimum 8 characters. If not respected, a red error occurs.

Clicking saving button I expect to submit the form, with or without password enabled, and if enabled with password longer at least 8 characters.

Clicking saving button I expect not to submit the form, with password enabled and password length shorter than 8 characters.

What happened instead:
With toggle enabled, password enabled and the password min length validation rule in place, I type a wrong password, long 3 characters.
I submit the form with password rule not respected. The validate prop is ignored, form is submitted anyway.

If the disabled prop is never set in <PasswordInput/>, validate prop works as expected.

Steps to reproduce:
Activate toggle for password field, type a short password, submit the form.

  const { resetField } = useFormContext();
  const [resetPasswordEnabled, setResetPasswordEnabled] = useState(false);
  const onChangePasswordResetEnabled = useCallback<ChangeEventHandler<HTMLInputElement>>((event) => {
    resetField('password');
    setResetPasswordEnabled(event.target.checked);
  }, [resetField]);

  return (
    <TabbedForm>
      <TabbedForm.Tab label="Label">
        <BooleanInput
          label="Activate password change"
          source="activator"
          checked={resetPasswordEnabled}
          onChange={onChangePasswordResetEnabled}
        />
        <PasswordInput
          name="password"
          source="password"
          required={resetPasswordEnabled}
          disabled={!resetPasswordEnabled} // with this line fully removed, validate works
          validate={[minLength(8, 'Password at least 8 characters.')]}
        />
      </TabbedForm.Tab>
    </TabbedForm>
  );
