Request to add timeout functionality to synchronous binds

Our client would like to put a timeout parameter in on the z/OS client side and are trying to understand if that's possible. They are using GLD.SGLDHDRC(LDAP) to compile their C routine and are wondering if there is anything equivalent to the LDAP_OPT_TIMEOUT and LDAP_OPT_NETWORK_TIMEOUT property fields.

Ldap_result() works with asynchronous LDAP ldap_simple_bind( ) call. The method uses a msgid to specify the message identifier assigned to the LDAP request. Currently they are using ldap_simple_bind_s( ) call, which is synchronous. They have concerns using an asynchronous bind and believe their application's bind calls are performing a cross forest authentication. If so, then this method will not work for them.

Their comment on the LDAP_OPT_TIMEOUT and LDAP_OPT_NETWORK_TIMEOUT properties:

Do you know why these two time out properties are not available in the LDAP system library on the mainframe:

GLD.SGLDHDRC, members LBER and LDAP:

ldap_set_option(connection, LDAP_OPT_TIMEOUT, (void *)&optTimeout)

ldap_set_option(connection,LDAP_OPT_NETWORK_TIMEOUT, (void *)&networkTimeout);

LDAP_OPT_TIMELIMIT is the only property that is available for them to use. But the other two time out related properties are closely related to the client side timeout, which is what they want to use. They have seen in online forums that they are available to Python, C, or Java versions of the code on other platforms.
