Single Sign-On (SSO)

If you have a windows network with Active Directory, then it's possible to login with single sign-on. It means that your browser negotiates your authentication credentials with the server running piler in the background.

Prerequisites

Make sure your clock is accurate, if necessary use ntpdate or other methods.

Verify /etc/resolv.conf settings to make sure your name resolution works properly. You may use the domain controllers as resolver dns servers.

Make sure /etc/samba/smb.conf is configured properly

[global]

workgroup = YOURDOMAIN
realm = YOURDOMAIN.YOURREALM
security = ADS

How to setup on Debian / Ubuntu

Install mod_auth_ntlm_winbind

apt-get install libapache2-mod-auth-ntlm-winbind samba
cd /etc/apache2/mods-enabled
ln -sf ../mods-available/auth_ntlm_winbind.load 

Restart winbind

/etc/init.d/winbind restart

Add the www-data user to the winbindd_priv group:

usermod -G winbindd_priv www-data

uid=33(www-data) gid=33(www-data) groups=33(www-data),125(winbindd_priv)

Restart apache

apache2ctl restart

Note: With Samba 4, you need the following symlink:

ln -s /var/lib/samba/winbindd_privileged/pipe /var/run/samba/winbindd_privileged/pipe

How to setup on Centos 7

yum install -y mod_auth_ntlm_winbind samba-winbind samba-winbind-clients samba-client

usermod -G wbpriv apache

setsebool -P allow_httpd_mod_auth_ntlm_winbind on
setsebool -P httpd_can_network_connect on

start winbind service

systemctl start winbind

Join to the domain

net ads join -U Administrator

Check the status with

net ads info
net ads lookup

and

wbinfo -g
wbinfo -u

restart apache

apachectl restart

Other steps

Create a helper account in AD. It will help piler to query user data when someone logs in.

Enable NTLM negotiation within the browser, and add the piler website

Firefox:

about:config
network.automatic-ntlm-auth.trusted-uris

Internet Explorer:

Tools
Internet Options
Security
Local Intranet
Sites

Last step: set the following in config-site.php:

$config['ENABLE_SSO_LOGIN'] = 1;
$config['LDAP_HOST'] = 'adserver.yourdomain.com';
$config['LDAP_HELPER_DN'] = 'CN=.....,DC=yourdomain,DC=com';
$config['LDAP_HELPER_PASSWORD'] = 'xxxxxxxx';
$config['LDAP_MAIL_ATTR'] = 'mail';
$config['LDAP_BASE_DN'] = 'dc=yourdomain,dc=com';

$config['REWRITE_MESSAGE_ID'] = 1;

Then whenever your users visit http://piler.yourdomain.com/, then they are redirected to sso.php, and logged in automatically, then redirected to the search page.

With SSO enabled, users in the local database, eg. admin@local, should go to http://piler.yourdomain.com/login.php

If anything goes wrong, then be sure to set “LogLevel debug” in apache to see what's going on.
