Help - Support of LDAP SortControl under Tomcat 4.0.1

[James Chiou]

Hi,

I wrote a java libary from where functions are called by some JSP pages running under 
Tomcat 4.0.1. In this library, I use Sun's LDAP Control Extension for LDAP Sort 
Control (exported from com.sun.jndi.ldap.ctl.SortControl), as following:

      ldapCtx = new InitialLdapContext(env, null);

      // Create the critical Sort control that sorts based on "uid"
      Control[] ctxCtls = new Control[] {
           new SortControl(new String[]{"uid"}, Control.CRITICAL)
      };

      // Set the context's request controls to be ctxCtls
      ldapCtx.setRequestControls(ctxCtls);

When I tested the code with a standalone java program (i.e., not running under Tomcat) 
it works just fine. However, when I run the code (called from a JSP page) under Tomcat 
4.0.1, I got the following error:
        javax.naming.OperationNotSupportedException: [LDAP: error code 12 - 
Unavailable Critical Extension];

I put 'ldapbp.jar' under a few different places under Tomcat home directory, including 
'lib', 'common\lib', etc. but got the same error. Any help you can give to get this 
resolved is appreciated. Thanks in advance.

Best Regards,
