For LDAP connection, if the value of com.sun.jndi.ldap.connect.timeout is set too small or not an optimal value for the system, after the socket is created and connected to the server, but the handshake between the client and server fails due to socket time out, the opened socket is not closed properly.

Fix request [11u] I backport this for parity with 11.0.22-oracle. Medium risk, small change for not supported attribute. Test passes. SAP nightly testing passed.
