    The cause:

    After researching your program for hours, I realize that your ldap.conf was previously configured with your IP address. However, the hostname ldap.techvictus.local actually is not an address, it is just a fake domain name. Therefore, you get the error: ”ldap_sasl_bind simple can’t contact ldap server (-1)”.

    Solution:

    I suggest that you should use the IP address of your system instead of using 127.0.1.1, or you can use FQDN after the IP address as the following:

    192.168.1.123 hulk.marvel.comics hulk
127.0.0.1 localhost

and the rest...

    To remove the fake domain name, you need to alter ldap.conf to get URI ldap://${IP_ADDRESS}

    Another way is trying: ldap://localhost

    If you follow the ways I suggest above, I sure that your error will go away.

  2. The hostname ldap.techvictus.local I think is not addressable (i.e. A hostname that can be resolved using an IP address.

    Use ldap://localhost
