Im using OpenLdap-2.2.24 on Linux. Ldap server is running on remote host and my client is coded with C API.

I'm only changing timeout value and with 500ms it doesn't work while with 1100 ms it works. Maybe there is problem with two ways of specifying timeouts? Im setting LDAP_OPT_NETWORK_TIMEOUT and Im also using timeout parameter in ldap_result functions. Just before this modify operation Im also doing ldap_search (with following ldap_result with also timeout set).
