Bind failed: Can't contact LDAP server: Unable to bind to server ldaps://...

Hi, im trying to connect to LDAP however , but I keep getting Bind failed: Can't contact LDAP server: Unable to bind to server ldaps://myserver . I have also tried downgrading to php8.1, enabled ldap extension in my php.ini and follow the instructions as mentioned on this link : (https://github.com/osTicket/osTicket-plugins/issues/276) but still not luck . It works fine when I try to connect using ldapsearch .

This is what I get from logs:

TypeError: ldap_close(): Argument #1 ($ldap) must be of type LDAP\Connection, bool given in phar:///var/www/html/Helpdesk/include/plugins/auth-ldap.phar/include/Net/LDAP2.php:701

Any help would be greatly appreciated .Thank you !

Until the next builds of plugins and new core get released you will need to unpack the plugin and apply the following:

https://github.com/osTicket/osTicket-plugins/pull/279

You will also need to apply the following but you will actually need to replace the corresponding directory in the plugin itself with the one in the pull:

https://github.com/osTicket/osTicket-plugins/pull/285

Hi Kevin! Thank you for your response. I applied the changes as per your suggestion from the provided link, but I'm still encountering the same error. I also reviewed the PEAR documentation and found a PHP code for testing the ldap connection but i still get the same results:

Could not connect to LDAP-server: Bind failed: Can't contact LDAP server: Unknown Net_LDAP2 Error (-1)PHP Fatal error: Uncaught TypeError: ldap_close(): Argument #1 ($ldap) must be of type LDAP\Connection, bool given in /usr/share/php/Net/LDAP2.php:701

Okay then connection definitely cannot be established. Check your AD logs for a reason why.

Cheers.
