It could be that your Active Directory is forcibly closing this connection by some kind of server-side policy.
If your goal is authentication and you operate only on Windows, you may want to look at http://waffle.codeplex.com. It does BASIC auth as well as Negotiate using Windows API, so you don't have to deal with configuring LDAP at all and get correct results (supports domain trusts, nested groups, etc.). dB. @ dblock.org Moscow|Geneva|Seattle|New York -----Original Message----- From: Manish Kumar [mailto:man...@oakdeneindia.com] Sent: Monday, June 21, 2010 10:52 AM To: 'Tomcat Users List' Subject: Tomcat - ADS connection reset - communication exception Hi Friends, I'm using tomcat 5.5.28 and ADS on Windows 2003 Server and connecting through realm configuration mentioning in the server.xml.
