Rational Synergy throws javax.naming.NamingException: LDAP response read timed out, timeout used:2000ms.

This is due to the timeout happening between Synergy server and RDS server. To avoid this problem increase the timeout value form 2000ms to a higher value, say 10000ms (10sec)

1. On Synergy server, open %CCM_HOME/etc/TDSConfiguration.xml
2. Modify"LDAP_CONNECTION_TIMEOUT" value from 2000 to 10000
3. Restart Synergy services
