How to check user and password, when I use Cas 3 and AuthenticationUserDetailsService

[KamilBek]

I use CAS and Spring Security 3.0. But I can't check password. How can I do it?
My configuration xml is:
<bean id="authenticationUserDetailsService" class="app.MyAuthenticationUserDetailsService"/>

<bean id="proxyGrantingTicketStorage" class="org.jasig.cas.client.proxy.ProxyGrantingTic ketStorageImpl"/>


<bean id="myPasswordEncoder" class="app.MyPasswordEncoder">
</bean>



<sec:http entry-point-ref="casProcessingFilterEntryPoint">
<sec:intercept-url pattern="/forgotpass.xhtml" access="ROLE_ANONYMOUS"/>
<sec:intercept-url pattern="/error.xhtml" access="ROLE_ANONYMOUS"/>
<sec:intercept-url pattern="/*.xhtml" access="ROLE_USER"/>

<sec:custom-filter ref="casAuthenticationFilter" after="CAS_FILTER"/>
</sec:http>



<sec:authentication-manager alias="authenticationManager">
<sec:authentication-provider ref="casAuthenticationProvider">
<sec: password-encoder ref="myPasswordEncoder"/>
</sec:authentication-provider>

</sec:authentication-manager>

</bean>

method of MyAuthenticationUserDetailsService returns UserDetail with username and encoded password.
MyPasswordEncoder encode it with same algorithm.
But 1)I put logs to MyPasswordEncoder and it doesn't riched
2) I try to enter to system with user 'admin' and password 'admin11'(it is right), but I can enter only with password 'admin'.

Is my way to check user and password wrong?
