Notes/Domino 6 and 7 Forum : Error connecting to LDAP server using JNDI

I have an agent which at the moment queries an LDAP directory and prints the results in the Java Console/Domino server console.

It connects to the LDAP server using JNDI which is included in ND6. When run locally everything works OK but when run on the server I get the following errors:

09/01/2003 03:34:44 PM Agent error: Exception in setContext: javax.naming.CommunicationException: uk-bre-sed1.abc.com:389 [Root exception is java.lang.SecurityException: uk-bre-sed1.abc.com,-1]
09/01/2003 03:34:44 PM Agent error: java.lang.NullPointerException
09/01/2003 03:34:44 PM Agent error: at JavaAgent.NotesMain(JavaAgent.java:118)
09/01/2003 03:34:44 PM Agent error: at lotus.domino.AgentBase.runNotes(Unknown Source)
09/01/2003 03:34:44 PM Agent error: at lotus.domino.NotesThread.run(NotesThread.java:208)

The LDAP directory is visible to all and the Domino server can ping the LDAP server and vice versa.

Any idea what I'm doing wrong??

Thanks in advance,
Mark.
