Hello,If I enable the LDAP plugin and attempt to log in using an agent username and password, I get an error in the browser and osTicket creates the following error in the PHP log: PHP Fatal error: Uncaught Error: Call to a member function bind() on null in phar:///var/www/root/support/include/plugins/auth-ldap.phar/authentication.phpStack trace:#0 phar:///var/www/root/support/include/plugins/auth-ldap.phar/authentication.php(427): LDAPAuthentication->authenticate('testuser', 'testpassword')#1 /var/www/root/support/include/class.auth.php(235): StaffLDAPAuthentication->authenticate('testuser', 'testpassword')#2 /var/www/root/support/scp/login.php(47): AuthenticationBackend:('testuser', 'testpassword', Array)#3 {main} thrown in phar:///var/www/root/support/include/plugins/auth-ldap.phar/authentication.php on line 220The error I get in Chrome is:The <website> page isn’t working<website> is currently unable to handle this request.HTTP ERROR 500The agent is set up with LDAP authentication in their user profile, and I believe the LDAP settings in the plugin configuration are correct. I've tested the LDAP user defined in the Search User field in the plugin configuration and they can connect and search the LDAP database without problems when using the LDAP search tool provided with the LDAP package.My osTicket version is as follows:osTicket Version v1.10Web Server Software Apache/2.4MySQL Version 10.1.14PHP Version 7.0.14LDAP plugin version v0.6.3This was also a problem when using PHP 5.6.22. Any ideas?Thanks.
