    LDAP Login Help

    Chris Buckley Newbie

      The code below I can get to work from a stand alone java application if I take the contents of the ejbCreate() and the createUpstrem... and put it in a main method. However when I try to make the following code execute as a session bean, it won't work. I'm not sure where the break down is. Below it the code I am using. Any help would be much appreciated.
