LDAP integration

[c0rp-aubakirov]

If I add LdapAuthenticationProvider, after login i see this error:

org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [lightadmin-dispatcher-redirector] in context with path [] threw exception [Request processing failed; nested exception is org.apache.tiles.request.render.CannotRenderException: ServletException including path '/views/layout/external-layout.jsp'.] with root cause
java.lang.NullPointerException
at     org.apache.tiles.template.DefaultAttributeResolver.computeAttribute(DefaultAttributeResolver.java:43)
at org.apache.tiles.template.InsertAttributeModel.resolveAttribute(InsertAttributeModel.java:165)

Could you please point me what to do? I Could provide code that I add if needed

Here is xml

<bean id="contextSource"
      class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
    <constructor-arg value="${ldap_url}"/>
    <property name="userDn" value="${user_dn}"/>
    <property name="password" value="${user_pass}"/>
</bean>

<bean id="ldapAuthProvider" lazy-init="true"
      class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
    <constructor-arg>
        <bean class="org.springframework.security.ldap.authentication.BindAuthenticator">
            <constructor-arg ref="contextSource"/>
            <!--<property name="userDnPatterns">-->
                <!--<list><value>${user_patterns}</value></list>-->
            <!--</property>-->
            <property name="userSearch" ref="userSearch"/>
        </bean>
    </constructor-arg>
    <constructor-arg>
        <bean
                class="org.springframework.security.ldap.userdetails.DefaultLdapAuthoritiesPopulator">
            <constructor-arg ref="contextSource"/>
            <constructor-arg value="${base_dn}"/>
            <property name="searchSubtree" value="true"/>
            <property name="groupRoleAttribute" value="${group_role_attr}"/>
            <property name="groupSearchFilter" value="${search_filter}"/>
        </bean>
    </constructor-arg>
</bean>

<bean id="userSearch" class="org.springframework.security.ldap.search.FilterBasedLdapUserSearch">
    <constructor-arg index="0" value="${base_dn}" />
    <constructor-arg index="1" value="${search_filter}" />
    <constructor-arg index="2" ref="contextSource" />
    <property name="searchSubtree" value="true" />
</bean>

I know that LDAP config works, because I see success messages in LDAP log files, but in lightadmin web interface logs error messages "java.io.IOException: ServletException including path '/views/layout/external-layout.jsp'".

While keeping this LDAP beans and configs, I still can normally login as admin/admin.

I found out that this is because of there is no needed role in my LDAP.
