   XMLBLASTER LDAP HOWTO  09/2001 [e-mail]

   See http://www.xmlblaster.org/xmlBlaster/doc/requirements/security.ldap.html


To get started with ldap authentication please
setup an ldap server first.


A practical example how to do this is described in
   
   xmlBlaster/demo/ldap/README.


If your ldap server is running fine and filled
with the demo data from
   
   xmlBlaster/demo/ldap/demoData.ldif


you can try this:


1. Start the xmlBlaster server:

      java -jar lib/xmlBlaster.jar


2. Start a client (all in one line), e.g.

      java HelloWorld3 -session.name tim -passwd tim -Security.Client.DefaultPlugin ldap,1.0

   In the log output of xmlBlaster server you should see something like:

      SecurityPluginManager] Plugin 'org.xmlBlaster.authentication.plugins.ldap.Manager' successfully initialized 

   Congratulations, you were authenticated by LDAP!


3. Edit xmlBlaster.properties and add this line:

      Security.Client.DefaultPlugin=ldap,1.0

   Now LDAP is switched on as default, try again:

      java HelloWorld3 -session.name tim -passwd tim


4. Now try an invalid password:

      java HelloWorld3 -session.name tim -passwd aaah

   You should get an authentication error from LDAP



Configuration of the LDAP plugin in xmlBlaster.properties:

   ldap.serverUrl=ldap://localhost:389/o=xmlBlaster,c=ORG
   ldap.rootDN=cn=Manager,o=xmlBlaster,c=ORG
   ldap.rootPwd=secret
   ldap.loginFieldName=cn

You may set these settings on command line as well:

   java -jar lib/xmlBlaster.jar \
         -ldap.serverUrl "ldap://localhost:389/o=xmlBlaster,c=ORG" \
         -ldap.rootDN "cn=Manager,o=xmlBlaster,c=ORG" \
         -ldap.rootPwd "secret" \
         -ldap.loginFieldName "cn"

NOTE: Authorization of actions (like subcribing/publishing/erasing messages)
      is not supported with this plugin,
      xmlBlaster logs warnings to notify you about this.
      If you want to implement authorization, please subclass

         org.xmlBlaster.authentication.plugins.ldap.Session
      
      and implement the method
      
         // actionKey is "SUBSCRIBE", "GET", "PUBLISH", "ERASE"
         // key is the ID of a message
         public boolean isAuthorized(String actionKey, String key)
         {
            DirContext ctx = ldap.getRootContext();
            // ... your LDAP queries to authorize the user action ...
            // return true if user may do this.
         }
