Configuring SAML Server as IDP

Modify the below files as per given parameters depending on your environment:

  • /var/simplesamlphp/config/config.php
'auth.adminpassword' => 'test@123',
'secretsalt' => 'ewt9ty348ty34ty3goy3gy3g',
'technicalcontact_email' => 'test@testlab.com',
'timezone' => 'Asia/Kolkata',		
'enable.saml20-idp' => true,
'enable.shib13-idp' => true,
'session.phpsession.cookiename' => null,
  • /var/simplesamlphp/config/authsources.php
'my-ldap' => array(
'hostname' => 'ad.testlab.com',
'enable_tls' => FALSE,		
'timeout' => 10,		
'dnpattern' => 'uid=%username%,cn=Users,dc=testlab,dc=com',	
'search.enable' => TRUE,
'search.base' => 'cn=Users,dc=testlab,dc=com',
'search.attributes' => array('cn'),		
'search.username' => 'test2',
'search.password' => 'Password@123',		
'priv.read' => TRUE,		
'priv.username' => 'test2',
'priv.password' => 'Password@123',		
  • /var/simplesamlphp/metadata/saml20-idp-hosted.php
'privatekey' => '/etc/apache2/ssl/wildcard.testlab.com.pem',
'certificate' => '/etc/apache2/ssl/wildcard.testlab.com.cer',
'auth' => 'my-ldap',	

Uncomment the below section:

'attributes.NameFormat' => 'urn:oasis:names:tc:SAML:2.0:attrname-format:uri',
'authproc' => array(
// Convert LDAP names to oids.
100 => array('class' => 'core:AttributeMap', 'name2oid'),
),

Disable the message signing as the NetScaler does not understand this signature type

$metadata['testlab-AD-CA'] = array (
  'entityid' => 'testlab-AD-CA',
  'contacts' => 
  array (
  ),
  'metadata-set' => 'saml20-sp-remote',
  'AssertionConsumerService' => 
  array (
    0 =>

Configuring Apache Server

Pointing Apache to SimpleSAMLphp by editing below file:

  • /etc/apache2/sites-available/000-default.conf
<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	DocumentRoot /var/www/html

	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined

Alias /simplesaml /var/simplesamlphp/www/
<Directory /var/simplesamlphp/www/>
Require all granted
</Directory>

</VirtualHost>
  • Now check if application is accessible over HTTP:
http://<ip-address-of-server>/simplesamlphp

Enabling SSL Access

  • Generate Certificates
cd /etc/apache2/
sudo mkdir ssl
sudo openssl genrsa -des3 -out Certificate.key 4096
sudo openssl rsa -in Certificate.key -out Certificate.pem
sudo openssl req -new -key Certificate.key -out Certificate.csr
sudo openssl x509 -req -days 9999 -in Certificate.csr -signkey Certificate.key -out Certificate.crt
  • Restart Apache
sudo a2enmod ssl
sudo service apache2 restart
  • Point Apache to use these Certificates by editing below config file:
/etc/apache2/sites-available/000-default.conf
<VirtualHost *:443>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        SSLCertificateFile      /etc/apache2/ssl/wildcard.testlab.com.cer
        SSLCertificateKeyFile   /etc/apache2/ssl/wildcard.testlab.com.pem
        SSLEngine On

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

Alias /simplesaml /var/simplesamlphp/www/
<Directory /var/simplesamlphp/www/>
Require all granted
</Directory>
</VirtualHost>
  • Restart Apache
sudo a2ensite ssl
sudo a2enmod ssl
sudo service apache2 restart
sudo phpenmod mcrypt
sudo service apache2 restart
  • Now the page should be available over https:
https://<ip-address-of-server>/simplesamlphp
