Ldap_search () [Function.ldap-search]: search:operatio_n_s error [

LDAP AD domain authentication ...

I can use the normal mode, including querying the user.
But today write a class, quote ldap_search () [Function.ldap-search]: search:operatio_n_s error

The code for the class is as follows

$ldapDN, this is the right one ...
Ldapbind () is also able to verify username and password ...
But the query of this user's details will be an error, the internet is prompted because the ad domain does not support anonymous, but I added the verification in search ... Also also reported wrong ...

When you do not use the class, Ldap_bind () is available ... Look at the following piece of code

Class Userldap {private $ldapHost;//ad server address private $ldapPort;//ad server port private $ldapDomin//ad Domain private $ldapDN = "ou=users,ou=xxx,ou=abc,dc=adv,dc=ccc,dc=com";    User list location private $userName;    Private $passWord; Public function __construct ($ldapDomin, $ldapHost, $ldapPort, $userName, $passWord) {$this->ldapdomin = $ldapDo        Min        $this->ldaphost = $ldapHost;        $this->ldapport = $ldapPort;        $this->username = $userName;    $this->password = $passWord; } Private Function Ldapconnect () {if (! $this->ldapconn = ldap_connect ($this->ldaphost, $this->ldapport        ) {$this->showerror = ldap_error ($this->ldapconn);        } else {$this->ldapconn = Ldap_connect ($this->ldaphost, $this->ldapport);    } return $this->ldapconn; Public Function Ldapbind () {if (@ldap_bind ($this->ldapconnect (), $this->ldapdomin.

Reply to discussion (solution)

Let's see if the arguments are passed correctly after you use the class, is the argument right?

The parameters are the same ....
So it's strange ...

Problem solved ...
Or the issue of the certification ...

I don't know if it can be said to be a threading problem ...
Before calling Ldap_search, you must satisfy the link to the LDAP server and pass the Ldap_bind authentication ...

And in function, after Ldap_bind, then Ldap_search, again link LDAP server, generated resource ID is not the same ... And this Resouce ID is not ldap_bind certified ...

So the way to change that is
When calling the function of GetUserInfo, we need to re-link the LDAP server again and obtain the user information through authentication, so that the error will not be ...
