Description:

I am trying to connect to a database using LDAP on my website and it keeps producing an error message: {message: "Invalid Credentials", exception: "Adldap\Auth\BindException",...} exception: "Adldap\Auth\BindException" file: "/var/www/simedarby.tth.asia/vendor/adldap2/adldap2/src/Auth/Guard.php" line: 109 message: "Invalid credentials" trace: [{file: "/var/www/simedarby.tth.asia/vendor/adldap2/adldap2/src/Auth/Guard.php"
Here is the code that I am currently using to connect to the LDAP server:

Please do let me know if the LDAP credentials that I am using is incorrect or if there is any tweaks to be made.
