I get this error when using WAMP:
Fatal error: Call to undefined function:
ldap_connect()
I have already edited the php.ini folder and enabled php_ldap.dll.
For some reason only some of the extensions show up in phpinfo() when I turn them on. I have restarted Apache and restarted my computer.
If you are a Windows user, this is a common error when you use XAMPP since LDAP is not enabled by default.
You can follow this steps to make sure LDAP works in your XAMPP:
[Your Drive]:\xampp\php\php.ini: In this file uncomment the following line:
extension=php_ldap.dll
Move the file: libsasl.dll, from [Your Drive]:\xampp\php to [Your Drive]:\xampp\apache\bin (Note: moving the file is needed only for XAMPP prior to version: 5.6.28)
Restart Apache.
You can now use functions of the LDAP Module!
If you use Linux:
For php5:
sudo apt-get install php5-ldap
For php7:
sudo apt-get install php7.0-ldap
If you are using the latest version of PHP you can do
sudo apt-get install php-ldap
running the above command should do the trick.
if for any reason it doesn't work check your php.ini configuration to enable ldap, remove the semicolon before extension=ldap to uncomment, save and restart Apache
