LDAP connection over SSL doesn't work with parameter “com.sun.jndi.ldap.connect.timeout”

Question

I have faced the problem that my application couldn't connect to LDAP server via SSL (LDAPS://ldapserver:636). It was always throwing the exception :

2014-08-07 12:52:13,486 ERROR : simple bind failed: ldapserver:636
javax.naming.CommunicationException: simple bind failed: ldapserver:636 [Root exception is javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake]

But after removed this line of code :

environments.put("com.sun.jndi.ldap.connect.timeout", "10000");

It works. Can anyone explain that how the timeout property affects the LDAP SSL connection?

Thanks, Stoper

Hmm. It shouldn't do that. The connection must have succeeded for there to be something for the server to close prematurely. — user207421

SSL handshake needs some time to exchange the keys/certificates before establishing an SSL channel. You could increase the time out to 20 sec/20000 ms and check if this indeed is the problem.
