I found an error in my configs and fix it but the problem remains.
In beans.xml I've added section with authenticator name:
<pre><security:IdentityImpl>
<s:modifies/>
<security:authenticatorName>jaasAuthenticator</security:authenticatorName>
</security:IdentityImpl></pre>
To make it working I've added patched version of seam-security (as recommended on <a href="https://community.jboss.org/message/740332#740332" target="_top" rel="nofollow" link="external">guvnor forum</a>).
And now I see login window and even can login, but after it I still get the same error messages like in <a href="http://drools.46999.n3.nabble.com/Guvnor-with-ModeShape-2-8-on-JBoss-7-tt4019923.html" target="_top" rel="nofollow" link="external">my previous message</a>.
