How to determine what version tls/ssl security protocol is connecting to LDAP (PHP)?

Question

I am using the openLDAP library. How do I determine what security protocol type and version my server is using to connect to the AD server?

ldap_connect("ldaps://server:636");

I understand for websites, I can easily see the type and version by looking at the properties from the browsers..

如另一个问题所建议，请查看ldap_set_option ，它带有许多选项，并且可以使用以下命令启用调试功能：

ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);
