LDAP and MSSQL

I am using phpmaker 2019.0.10. I was able to connect to Active Directory when using mysql. I am now generating some code from a mssql database and unable to find any reference to LDAP in the phpfn15.php file although it is seen under Tools–Advanced Settings. When i used mysql i also did some edits to the LDAP code in the phpfn15 file. I now wish to do the same with the generateeld code from mssql connection. Where can i find the LDAP class code?

Set Tools > Advanced Settings > “Authentication mode” to “LDAP”, generate scripts again and you will see the class in phpfn*.php.
