Hello OpenLdap Developers,

I haven't heard anything about the two bugs I've submitted in the jldap libraries, so I'd like to explain why I feel that these two issues are important to have fixed.

I'd like to create a new LdapConnection with a custom LdapSocketFactory and I want a timeout value set on the socket so that the connect method will timeout in case there is no route to the host or some other networking issue. The documentation leads me to believe that I can do the following.

LdapConnection.setSocketFactory(new LDAPJSSESecureSocketFactory()); int timeout = 5000; // 5 second timeout lc = new LdapConnection(timeout); lc.connect ("127.0.0.1", 636);

This won't work because the LdapConnection(int) constructor disregards the LdapSocketFactory that is set with the setSocketFactory method and instead uses the default non-SSL encrypted socket. Ok, lets try a workaround.

lc = new LdapConnection(new LDAPJSSESecureSocketFactory()); int timeout = 5000; // 5 second timeout lc.setTimeout(timeout); // <--- causes a nullPointerException lc.connect("127.0.0.1", 636); // Program never even gets here.

Ok, this is even worse. I now get a nullPointerException in the jldap library itself. Again, nothing in the documentation says to avoid setting the timeout until after you call connect()

lc = new LdapConnection(new LDAPJSSESecureSocketFactory()); int timeout = 5000; // 5 second timeout lc.connect("127.0.0.1", 636); lc.setTimeout(timeout);

Well, that works, but I'm not setting the timeout until after the connect which isn't what I need. What follows is the only way I can think of getting it to work.

class TimeoutLdapSocketFactory extends LDAPJSSESecureSocketFactory {

m_timeout = 0;

TimeoutLdapSocketFactory() { super (); }

TimeoutLdapSocketFactory(int timeout) { this(); m_timeout = timeout; }

Socket createSocket (host, port) { Socket socket = super.createSocket(host,port); if (timeout > 0) socket.setSoTimeout(m_timeout); return socket; }

lc = new LdapConnection(new TimeoutLdapSocket(timeout)); lc.connect("127.0.0.1", 636);

That's a lot of code to do what is already there in the LdapConnection class. If either of the two bugs I've submitted is fixed, then the above use case would be easy to do with-out the uglyness above. I believe #5142 to be a serious bug indeed since it can lead to a nullPointerException in the library.

Thank you, Tim Nowaczyk
