    Authenticator component missing

    Deepa Datar Newbie

      I have written a ldap login module using seam. I followed the steps as mentioned in this link http://www.seamframework.org/Documentation/ConfigureSeamWithOpenLDAP


      I am getting this exception when I am trying to access the login page:

          I made the following settings:


          In components.xml:


          
              <security:identity 
          
                   authenticate-method="# authenticator.authenticate}"

                jaas-config-name="NxJ_JAAS_LDAP"/>
          
          



          In login-config.xml

            The authenticate-method and jaas-config-name attributes are mutually exclusive, i.e. you can only have one or the other, not both.  And besides that, your EL expression is malformed also - it should be:



            authenticate-method=#{authenticator.authenticate}


            • 3. Re: Authenticator component missing
              Shane Bryzak Master

              Sorry, forgot the quotes.. it should be:



              authenticate-method="#{authenticator.authenticate}"

                Hi Shane,


                I made a typo when I was posting the message.


                1. The authenticate-method is correct.


                2. Since you mentioned that authenticate-method and jaas-config-name are mutually-exclusive, I changed it to.


                
                <security:identity 
                
                          remember-me="true" 
                
                           jaas-config-name="NxJ_JAAS_LDAP"/>
                
                



                But still I have the same error.


                Thanks

                  I can't believe you get the same error, i.e. Target Unreachable, identifier 'authenticator' resolved to null when you've removed the authenticate-method attribute.  Where is the 'authenticator' reference coming from otherwise?

                    Hi Shane


                    This is what I have in pages.xml:


                    
                    <page view-id="/login.html" action="#{authenticator.login}">
                    
                              <navigation from-action="#{authenticator.login}">
                    
                                   <redirect view-id="/pages/index.jsp"/>
                    
                              </navigation>
                    
                    </page>
                    
                    



                    Thanks

                      You need to remove the reference to authenticator from here.  If you really want to attempt authentication when the user first navigates to the login.html page, then the action should be #{identity.login} instead.

                        I had the same problem. Jboss couldn't find any identifier and I it was a clean create-project from seam-gen. My mistake was:


                        eclipse: JDK 1.6
                        jboss: running with JDK 1.5


                        I switched in eclipse to JDK 1.5 and everything just worked fine!


                        I hope, I can help somebody not spending two hours on this (like I did)
