Php ldap search operations error

Forum GLPI-Project

After the upgrade I can fetch users no more. The «test» button gives an «OK» to the connection, but in the php-errors.log I find this:

I edited the domain names and ips. What is strange is that the rootdn_password is empty, but I’m sure I filled it in directly in the db.

Well I tried to fill in again but then the script for ldap import complains with bad credentials. I filled the password in from the web interface and it connects. Anyway it can’t import anything.

Operations error encountered once more during Ldap_search() search

It makes me curious if there exists any additional error information that you can retrieve. My past experience with LDAP suggests that there might be additionalText that can provide more details about the event that occurred, instead of just «operations error». Since Operations Error encompasses multiple situations, it would be helpful to specify it more. If your other searches are functional, then it is likely a problem with your query. However, if they are not working, then it could be a problem with the server or the bind.

Ldap_search(): Search: Operations error again

Hi everyone,

Despite searching through stackoverflow and other platforms, I couldn’t find a solution to my question which may seem like a deja-vu. My goal is to create a function that starts with Connection To Ldap , validates the user’s id and password, and determines the group they belong to. When I initially created this function as a single entity, it worked as intended. However, I decided to split it into three different functions to manage it more efficiently. Currently, I have a function that establishes a connection with ldap.

The function provides an LDAP link identifier to confirm that the connection is established successfully.

Next, there is a function that verifies the login and password.

 public function checkLoginPwd($login, $pwd) < $ldapConnexion = $this->ldapConnection(); if ($bind = ldap_bind($ldapConnexion, $login, $pwd)) < return true; //ldap_close($ldapConnexion); >else < return false; >> 

The particular function that is causing me difficulty.

 public function checkUserRights($login, $pwd, $ldapConnection) < //Récupération login $loginAccount = "(sAMAccountName=$login)"; //Suppression de "myGroup\" $filter = str_replace("myGroup\\", "", $loginAccount); $attr = array("memberof"); //Recherche $result = ldap_search($ldapConnection, LDAP_BASE_DN, $filter, $attr); $entries = ldap_get_entries(ldap_connect(LDAP_SERVER), $result); foreach ($entries[0]['memberof'] as $grps) < if (strpos($grps, "VPN")) < $access = 2; break; >if (strpos($grps, "Users")) $access = 0; > if ($access != 0) < $_SESSION['user'] = $login; $_SESSION['access'] = $access; return true; >else

When attempting to connect using this method, an error message ( ldap_search ) appears during the search ( Operations error ), although it may still work when executed in one attempt.

It would be greatly appreciated if someone could assist me.

Upon running a var dump of $filter, it displays the string ‘(sAMAccountName=myLogin)’. The $ldapConnection is a resource with a value of ’13, ldap link’. Meanwhile, LDAP_BASE_DN is a string with the value of ‘DC=myGroup, DC=fr’. Furthermore, $attr is an array with a size of 1, and its only value is the string ‘memberof’ with a length of 8.

After spending several hours searching, I discovered a solution that may be helpful to others. In my checkUsersRights function, I incorporated two additional lines. Here, I am sharing the solution.

 $ldapConn = ldap_connect(LDAP_SERVER); ldap_bind($ldapConn, $login, $pwd); 

Previously, I attempted to establish a new connection before invoking my function. However, I realized that it was necessary to establish the connection within the function and utilize ldap_bind to ensure proper connection. I hope this insight will prove useful to someone in the future.

My wish is that this will be of assistance to you. It is possible that the filter you are utilizing may be problematic. Our method for drawing in users involves ldap and windows server 2008.

How to overcome the error «Operations error» in ldap_search() function in php

To fetch data from my Active Directory, I require filtering only those entries where the surname begins with ‘S’. However, the LDAP_Search() function is throwing an error. The error message reads «ldap_search(): Search: operations error «.

I have included the above code lines, yet the error persists despite adding the following: — ldap_set_option($ds, LDAP_OPT_REFERRALS, 0) — ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION , 3)

echo "
LDAP query test
"; echo "Connecting . "; $ds=ldap_connect("XXXXXXXXX"); // must be a valid LDAP server! echo "connect result is " . $ds . "
"; ldap_set_option($ds, LDAP_OPT_REFERRALS, 0); ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3); if ($ds) < echo "Binding . "; $r=ldap_bind($ds); // this is an "anonymous" bind, typically // read-only access echo "Bind result is " . $r . "
"; echo "Searching for (sn=S*) . "; // Search surname entry $sr=ldap_search($ds, "o=IT*, co=SL", "sn=S*"); echo "Search result is " . $sr . "
"; echo "Number of entires returned is " . ldap_count_entries($ds, $sr) . "
"; echo "Getting entries . 
"; $info = ldap_get_entries($ds, $sr); echo "Data for " . $info["count"] . " items returned:
"; for ($i=0; $i"; echo "first cn entry is: " . $info[$i]["cn"][0] . "
"; echo "first email entry is: " . $info[$i]["mail"][0] . "
"; > echo "Closing connection"; ldap_close($ds); > else < echo "
Unable to connect to LDAP server
"; > 

The expected outcome is to retrieve every last name that commences with the letter ‘S’.

Although I am not well-versed in PHP LDAP or AD, I have doubts about the asterisk present in your root DN. If it is an actual asterisk, it must be escaped. Otherwise, I am perplexed as to why you are unaware of your root DN.

I’m curious if there is additional error information available beyond Operations Error that could provide more insight into what happened. In my experience with LDAP, there is often additionalText available. Since Operations Error can cover a variety of scenarios, it would be helpful to narrow down the problem. If other searches are successful, then the issue could be with your query. However, if other searches fail, it could be due to a problem with the bind or server. I noticed you are using an anonymous bind, so I’m wondering if anonymous searches are allowed as well.

Warning: ldap_search(): Search: Bad search filter

My aim is to develop a PHP-based login webpage.

The objectives are: 1. Allowing the user to log in with their Windows login credentials. 2. Directing the user to a specific page based on their group membership.

The initial objective has been accomplished, but the focus must now shift to the second goal.

Upon executing the script, an error occurs.

Warning: ldap_search(): Search: Bad search filter 

$ldap['user'] = "domain\user123"; $ldap['pass'] = "password123"; $ldap['host'] = 'site.domain.com'; $ldap['port'] = 389; $ldap['dn'] = "DC=site, DC=domain, DC=com"; $ldap_user_group = "User"; $ldap_manager_group = "Admin"; $ldap['conn'] = ldap_connect( $ldap['host'], $ldap['port'] ) or die("Could not connect to " ); $ldap['bind'] = ldap_bind($ldap['conn'], $ldap['user'], $ldap['pass']); if( !$ldap['bind'] ) < echo "Login Failed"; >else if( $ldap['bind'] ) < $filter = "(sAMAccountName=" . $ldap['user'] . ")"; $attr = array("memberof"); $result = ldap_search($ldap['conn'],$ldap['dn'], $filter, $attr) or exit("Unable to search LDAP server"); $entries = ldap_get_entries($ldap['conn'], $result); ldap_unbind($ldap); foreach($entries[0]['memberof'] as $grps) < if (strpos($grps, $ldap_manager_group)) < //redirect to Admin page >if (strpos($grps, $ldap_user_group)) < //redirect to User page >> 

I’m completely baffled since I have no clue about the source of this error.

The search filter malfunctions when a slash is included in it. The filter includes \ \ \ \ \ \$ldap\[‘user’\]\ =\ «domain\user123»;\ \ \ \ and $filter = «(sAMAccountName=» . $ldap[‘user’] . «)»; .

$filter = «(sAMAccountName=user123)»; may be necessary depending on the configuration of your AD.

Error in Active Directory: «ldap_search: «Search: Other (e.g., implementation specific) error»

This issue occurs while utilizing the ldapfilter with the «has value» feature.

ldap_search($conn, "OU=Home,DC=local,DC=intra", "(&(cn=*))"); 

The filter can include either the condition «(&(cn=*))» or «(&(someattr=somevalue)(anyAttribute=*))», as well as any condition where the attribute «someattr» has any value.

Encountered an error during the search using ldap_search() function that is not related to any defined error type, such as implementation-specific error.

The filter with the condition «&(cn=*my*name*)» functions properly, however, if any attribute within the filter contains only «*», it will result in failure.

ldap_set_option» refers to a function or method that involves setting a certain option related to LDAP (Lightweight Directory Access Protocol).

ldap_search() and ldap_get_entries() error when attempting an Auth #40

ldap_search() and ldap_get_entries() error when attempting an Auth #40

Comments

Hello, I just started trying to get your repo to work on my laravel7 project (on Ubuntu 18.04 with Apache2 and PHP7.4 I think — is there a quick way to find out the PHP version in laravel? without having to create a php.ini and a route towards it in the web.php?)
But unfortunately, I keep getting
PHP Warning: ldap_search(): Search: Bad search filter in /var/www/html/zert/vendor/adldap2/adldap2/src/Connections/Ldap.php on line 286
PHP Warning: ldap_get_entries() expects parameter 2 to be resource, bool given in /var/www/html/zert/vendor/adldap2/adldap2/src/Connections/Ldap.php on line 143

when trying to attempt a login in tinker:
Auth::attempt([‘username’ => ‘einstein’, ‘password’ => »])

After some googling I found out, that I was somehow able to make the Auth via the adldap2::attempt() command I think it was — I cannot remember, have been trying to troubleshoot this problem for over 3 days now and can’t find it.

I’m trying to connect to an Active Directory and the connection does work using a GUI («Ldapadmin»).

Can you help me out, or let me know what other information you need/where else I can try my luck?
