LDAP_OPT_SSL_TIMEOUT

Edit online

Use the LDAP_OPT_SSL_TIMEOUT setting to specify in seconds the SSL inactivity timer.

After the number of seconds specified, in which no SSL activity occurs, the SSL connection is refreshed with new session keys. A smaller value can help increase security, but has a small affect on performance. The default SSL timeout value is 43200 seconds. For example: 
   value = 100;
   ldap_set_option( ld, LDAP_OPT_SSL_TIMEOUT, &value );
   ldap_get_option( ld, LDAP_OPT_SSL_TIMEOUT, &value)
Note: If you use LDAP_OPT_SSL_TIMEOUT and you are not running on an SSL version of IBM® Verify Directory, an error is returned.
