I receiving an error when i am trying to use LDAP with Laravel 5.5

"Use of undefined constant LDAP_OPT_PROTOCOL_VERSION - assumed 'LDAP_OPT_PROTOCOL_VERSION'"

However, i have enabled the PHP extension of LDAP

$ php --ini |grep ldap

/etc/php.d/ldap.ini,

and

$ cat /etc/php.d/ldap.ini
; Enable ldap extension module
extension=ldap.so

and php information

$ php --info |grep ldap
/etc/php.d/ldap.ini,
Protocols => dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtsp, scp, sftp, smtp, smtps, telnet, tftp
ldap

I am using

$ php -v

The issue is solved.

I installed the LDAP libraries and recompiled the PHP with LDAP from scratch.

./configure --other-extensions --with-ldap --enable-ldap
