hello everyone, radius PECL extension works well on XAMPP but unexpectedly on other Servers(IIS windows server 2016 &OR& httpd version 2.4.6 (on centos 7-6); all 64x). I have a php login page which authenticate users through a freeradius server hosted by linux. The freeradius uses MariaDB 5.5.60 to store its database. In radcheck table, the attribute assigned to to users' password is Cleartext-Password. Freeradius Server Info: OS:centos-release-7-6.1810.2.el7.centos.x86_64 Radius server:FreeRADIUS version 3.0.13, for host x86_64-redhat- linux-gnu The login page uses PHP (Version 7.2.15) and the radius PECL extension (version 1.4.0b1); all in 64x. On XAMPP: the authentication request sends the user's password as a clear text as expected. On other webserver: the authentication request sends the user's password as an encrypted text. I do not want this module to encrypt the password. I could not figure out which encryption this is, or at which position it happens. I need help deactivating this encryption. It would also be nice if you could provide some reference that explains encryption in freeradius server. // PHP LOG IN Function function radiusLogin($username, $password){ $msg=''; $hostname='192.168.0.22'; $port='1812'; $secret='radiusPass'; $timeout='3'; $max_tries='3'; $radius_handle= radius_auth_open(); radius_add_server($radius_handle, $hostname, $port, $secret, $timeout, $max_tries); radius_create_request($radius_handle, RADIUS_ACCESS_REQUEST); radius_put_attr($radius_handle, RADIUS_USER_NAME, $username); radius_put_attr($radius_handle, RADIUS_USER_PASSWORD, $password); $result = radius_send_request($radius_handle); try { switch ($result) { case RADIUS_ACCESS_ACCEPT: $msg='ACCEPT'; break; case RADIUS_ACCESS_REJECT: $msg='REJECT'; break; case RADIUS_ACCESS_CHALLENGE: $msg='CHALLENGE'; break; default: $msg='FAILED'; } } catch(Exception $e) { $msg=$msg.'<br>'.$e->getMessage(); } return $msg; } // the debug mode shows: ..
