    <p>I have a LDAP PHP class which works on all other PHP installations in our company. However, the code stopped working now that I changed from SuSE to Ubuntu 11.04. The PHP version is 5.3.5.</p> <p>I try to connect to our LDAP server. After connecting to it I try to run ldap_search. It fails with the error message 'ldap_search(): Search: Can't contact LDAP server'. I had a look into the traffic using wireshark and could see communication happening between php and ldap, alas no connection happened.</p> <p>Thanks for your thoughts, Uwe</p> <p>Here is the code I use:</p> <pre><code>class ldap{ private $ldap_conn; private $ldaphost; private $ldapport; public function __construct () { $this-&gt;ldaphost = 'ldaps://ourserver.co.nz'; // obviously a fake name $this-&gt;ldapport = 636; $this-&gt;ldap_conn = ldap_connect($this-&gt;ldaphost, $this-&gt;ldapport) or die("Could not connect to $this-&gt;ldaphost"); } public function signin ($username,$password, $applicationName) { $dn = "o=MY_COM"; $filter="(cn=$username)"; $justthese = array("dn","fullname", "mail"); $sr=ldap_search($this-&gt;ldap_conn, $dn, $filter, $justthese); $people = ldap_get_entries($this-&gt;ldapconn, $sr); if (!$people || count($people) == 0 || $people['count'] == 0) { //Nothing found, quit. return AUTH_ERROR_NO_DN; } $dn = ($people[0]['dn']); if (($dn!='')&amp;&amp;($password!='')) { $loginStatus = @ldap_bind($this-&gt;ldapconn, $dn, $password); if ($loginStatus) { $fullname = $people[0]['fullname'][0]; if ($fullname=='') { $fullname =$dn; } $user = array( 'logged_in_dn' =&gt; $dn, 'password' =&gt; $password, 'username' =&gt; $fullname, 'cn' =&gt; $username, 'mail' =&gt; $people[0]['mail'][0], 'status' =&gt; 'AUTHENTICATED' ); } else { $user = array( 'status'=&gt; array('AUTH_ERROR_WRONG_PASSWORD'), 'details' =&gt; array( 'logged_in_dn' =&gt; '', 'password' =&gt; '', 'username' =&gt; '', 'cn' =&gt; '', 'mail' =&gt; '', 'status' =&gt; 'AUTHENTICATED' ) ); } } else { $user = array( 'status'=&gt; array('AUTH_ERROR_NO_DN'), 'details' =&gt; array( 'logged_in_dn' =&gt; '', 'password' =&gt; '', 'username' =&gt; '', 'cn' =&gt; '', 'mail' =&gt; '', 'status' =&gt; 'AUTHENTICATED' ) ); } return $user; } </code></pre> <p>This is the unit test executing the methods: class unit_ldapConnectTest extends TadPhpUnitTestCase</p> <pre><code>{ function testLdapconnection () { $ldap = new LDAP(); $user = $ldap-&gt;signin('myname','password',''); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
