LDAP connection not working (own php script does!)

[Apollo13]

Hi guys,

I am trying to setup a working LDAP auth server connection, but the only response I get when I click "Select" to show the Authentication containers is a blank popup - and in my logs I can see "opnsense: LDAP bind error (Can't contact LDAP server)". I am using StartTLS and I suppose there must be an error in my config, but I cannot figure out what to change.

My server has a certificate with its FQDN set as CN and the (self-signed) root and intermediate CAs are added (as separate entries) to the list of CAs shown via "System" -> "Trust" -> "Authorities".

If I try the following script (I put it in the same directory as all the other php files, i.e. /usr/local/www) using the values from the LDAP config page I get a list of all attributes for "my.user":

Code: [Select]

<?php
   $ldap="ldap-srv.mydomain.com";
   $usr="uid=srv-acc,ou=serviceaccounts,dc=sub,dc=mydomain,dc=com";
   $pwd="secret";
 
   $ds=ldap_connect($ldap);
   $ldapbind=false;
   if(ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3))
      if(ldap_set_option($ds, LDAP_OPT_REFERRALS, 0))
         if(ldap_start_tls($ds))
             $ldapbind = @ldap_bind($ds, $usr, $pwd);   
             $ldapse = ldap_search($ds,"dc=sub,dc=mydomain,dc=com","uid=my.user");
             var_dump(ldap_get_entries($ds,$ldapse));
    
   ldap_close($ds);
?>
The same username and password work if I use them inside a LDAP auth stanza in my Apache2 config.

I also tried setting "TLS_REQCERT never" in /usr/local/etc/openldap/ldap.conf but that doesn't change anything.

Can anybody tell me what I am doing wrong?
