Authenticating user using LDAP from PHP

Question

My project is to make a module enrollment system for our university. So I contacted the IT people in my university for details to authenticate the students into the system.

Answer 1

@Stephen provided good points. Here is my plain PHP code to authenticate using AD:

1. first you need to know this parameters: server host, user domain (you need also base dn if you want query AD).

2. use the following code:

   $ldap = ldap_connect($host); // e.g. 165.5.54.6 or an URL
   ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3); // Recommended for AD
   ldap_set_option($ldap, LDAP_OPT_REFERRALS, 0);
   $bind = ldap_bind($ldap, $username.'@'.$userDomain, $passwrod);
   
   if($bind){
   // successful authentication. 
   }
