Subject Re: classcast on ApacheDS
Date Wed, 22 Apr 2009 13:18:15 GMT
Hey,

via jdni calls I guess, seam's ldap-identity-store is taking care of...
lemme elaborate the case,

Actually before creating a user, the seam framework is doing a search with
userExists method.

  public boolean userExists(String name)
   {
      InitialLdapContext ctx = null;
      try
      {
         ctx = initialiseContext();

         String[] userAttr = {getUserNameAttribute()};

         SearchControls controls = new SearchControls();
         controls.setSearchScope(searchScope);
         controls.setReturningAttributes(userAttr);
         controls.setTimeLimit(getSearchTimeLimit());

         StringBuilder userFilter = new StringBuilder();

         Object[] filterArgs = new Object[getUserObjectClasses().length];
         for (int i = 0; i < getUserObjectClasses().length; i++)
         {
            userFilter.append("(");
            userFilter.append(getObjectClassAttribute());
            userFilter.append("={");
            userFilter.append(i);
            userFilter.append("})");
            filterArgs[i] = getUserObjectClasses()[i];
         }

         NamingEnumeration answer = ctx.search(getUserContextDN(),
userFilter.toString(), filterArgs, controls);
         while (answer.hasMore())
         {
            SearchResult sr = (SearchResult) answer.next();
            Attributes attrs = sr.getAttributes();
            Attribute user = attrs.get(getUserNameAttribute());

            for (int i = 0; i < user.size(); i++)
            {
               Object value = user.get(i);
               if (name.equals(value))
               {
                  answer.close();
                  return true;
               }
            }
         }
         answer.close();
         return false;
      }
      catch (NamingException ex)
      {
         throw new IdentityManagementException("Error getting users", ex);
      }
      finally
      {
         if (ctx != null)
         {
            try
            {
               ctx.close();
            }
            catch (NamingException ex) {}
         }
      }
   }

and this is throwing out,
