PHP LDAP connection with AD LDS
I am trying to write some PHP to query an AD LDS / LDAP (2012 R2) instance and I cannot connect it. I am currently configured as an unencrypted connection (prod will be ssl / tls).
- I can connect to my LDAP instance via ldapsearch and execute queries
- I can connect via LDP on my windows.
- I can ping the LDAP server and telnet to the port from my nix window.
- Tried full rdn for username
- Tried the URI (ldap: // ldapserver: 50001 or passed the port as native var)
I rewrote the code a million times thinking it was some syntax error or something wrong. $ ldapconn returns "Resource Id # 2" which looks correct in the PHP manual. I'm stumped. Is there any additional debugging I can enable?
Here is his error:
Warning: ldap_bind (): Unable to bind to server: Unable to bind to LDAP server in / usr / share / nginx / html / logintest 3.php on line 20
Here's the relevant code:
// all the debugging ini_set('display_errors', 'On'); ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7); $ldapuser = "ldapbind"; $ldappassword = "ldapbinder"; $ldapserver = "ldapserver"; $ldapport = 50001; // connect to ldap server $ldapconn = ldap_connect($ldapserver, $ldapport) or die("Could not connect to $ldapserver"); // check if ldap_connect returned a resource value if($ldapconn) echo "$ldapconn"; // attempting bind $ldapbind = ldap_bind($ldapconn, $ldapuser, $ldappassword); echo "Ldap connection debug: " . ldap_error($ldapconn) . "\n";
