Using HTTP header (external authentication) is already the potentially simplest way to go. It would be good to know what you have tried in that regard and where you failed.
Alternatively, you could use a custom authentication filter / user factory in the Share application and generate a link to the Share UI that includes a one-time token your JSF application registered with Share to pass along a pre-established authentication via the link to the UI.

Axel, thank you!
For custom authentication filter should we change web.xml like that?
<java>
   <filter>
      <description>Custom Authentication</description>
      <filter-name>CustomAuthenticationFilter</filter-name>
      <filter-class>ru.mycompany.repo.authentication.CustomAuthenticationFilter</filter-class>
   </filter>

   <filter-mapping>
     <filter-name>CustomAuthenticationFilter</filter-name>
      <url-pattern>/page/*</url-pattern>
   </filter-mapping>

   <filter-mapping>
     <filter-name>CustomAuthenticationFilter</filter-name>
     <url-pattern>/p/*</url-pattern>
   </filter-mapping>
</java>

<java>
public class CustomAuthenticationFilter implements Filter
{

   @Override
   public void init(FilterConfig filterConfig) throws ServletException
   {
       //…
   }

   @Override
   public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
   {
      ???
   }

   @Override
   public void destroy()
   {
      //…
   }
}
</java>

That is one option. Alternatively, people have been using the <a href="http://docs.oracle.com/javaee/6/tutorial/doc/bnagb.html">WebFilter annotation</a> to avoid having to modify the web.xml file altogether.

For external authentication via HTTP Header I've followed the steps

1. renamed alfresco-4.2.e/tomcat/shared/classes/alfresco/web-extension/share-config-custom.xml.sample as share-config-custom.xml.
2. Uncommentd both the <config evaluator="string-compare" and the condition="Remote"> sections.

<config evaluator="string-compare" condition="Remote">
      <remote>
         <endpoint>

   </config>

3. modified alfrsco-global.properties like ;

authentication.chain=external1:external,alfrescoNtlm1:alfrescoNtlm
external.authentication.proxyUserName=
external.authentication.enabled=true
external.authentication.defaultAdministratorUserNames=admin
external.authentication.proxyHeader=SsoUserHeader

Eclipse- SSO Filter class

public class SsoFilter implements Filter{

   public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)

        throws IOException, ServletException

    {

      // if the ServletRequest is an instance of HttpServletRequest
            if (request instanceof HttpServletRequest) {
               HttpServletRequest httpServletRequest = (HttpServletRequest) request;
               // Creating an instance of my custom request
               AlfrescoHttpServletRequestWrapper requestWrapper = new AlfrescoHttpServletRequestWrapper(httpServletRequest);
               // sending my custom request instead of the regular request
               chain.doFilter(requestWrapper, response);
            } else {
               chain.doFilter(request, response);
            }

            return;

   }
}

but unable to succeed .
