Issue connecting ldp.exe to LDAPS GSLB setup

I have encountered an issue while attempting to connect ldp.exe to a GSLB (Global Server Load Balancing) setup for LDAPS on SSL_TCP. The GSLB configuration is similar to the load balancer server's SSL_TCP on port 636. However, when I try to establish the connection, I receive the following error message:


 ld = ldap_sslinit("laps.abc.com", 636, 1);
Error 81 = ldap_set_option(hLdap, LDAP_OPT_PROTOCOL_VERSION, 3);
Error 81 = ldap_connect(hLdap, NULL);
Server error: <empty>
Error <0x51>: Fail to connect to laps.abc.com.


Interestingly, when I attempt to connect directly to the load balancer's single site IP, everything appears to be functioning correctly. I'm uncertain as to what may be missing or misconfigured on the GSLB side.

I would appreciate any advice or guidance you can provide.
