• Shibboleth WAYFless URLs UKFederation

  Date: 2009.10.27 | Category: shibboleth, single sign on, sso, ukfederation, wayfless | Response: 0

  Shibboleth is a single sign on method used by UK schools.
  Shibboleth allows you to log into multiple services without the need to enter your username and password.
  
  
  Shibboleth WAYFLess URLS is a
  knowledge requirement for Shibboleth Service Providers and users. A shibboleth user may use a service frequently and want to skip the Identity provider selection page, a wayfless URL does exactly this.

  Example

  
  
  
  
  Copy and paste the above and replace %20 with ?

  What bit do I need to change to configure my service to Primary Logon?

  The bits in bold need changing.

• Configuring Apache for Shibboleth on CentOS to the ukfederation w/ Godaddy certs

  Date: 2009.10.27 | Category: certificates, csr, godaddy, janet, key, openssl, shibboleth, ukfederation | Response: 1

  Part 3. Apache config. (1 hour)

  cd /etc/shibboleth
  openssl genrsa -des3 -out external.key 2048
  openssl req -new -key external.key -out external.csr
  

  The above will create a CSR request for your resource, when asked what the common name is enter something like shib.yourdomain.com - DO NOT use sp.yourdomain.com or the same common name as you used to register your SP!

  Edit the CSR and copy its contents into clipboard. Then login to your godaddy hosting account and paste the CSR request into your certificate request.

  Godaddy will do their thing then get back to you with a CRT a few files usually within 24 hours.

  When they get back to you with the files copy or download them the files to /etc/shibboleth

  Rename shib.yourdomain.com.crt to external.crt

  Rename gd_bundle.crt to external_int.crt and place it in /etc/shibboleth

  Edit /etc/httpd/conf.d/ssl.conf

  Replace

  SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

  With

   SSLCertificateKeyFile /etc/shibboleth/external.key

  Replace

  SSLCertificateFile /etc/pki/tls/private/localhost.crt

  
  

  With

  SSLCertificateFile /etc/shibboleth/external.crt

  Under SSLCertificateKeyFile paste SSLCertificateChainFile /etc/shibboleth/external_int.crt

  Edit /etc/httpd/conf/httpd.conf

  Replace

   UseCanonicalName Off

  With

   UseCanonicalName On

  Find the line beginning with ServerName

  Comment it out

  Below it type ServerName shib.yourdomain.com:80

  
  

  /usr/sbin/apachectl restart

  
  /usr/sbin/apachectl start
  

  The above commands will restart Apache or start it if it hasn't already been started

  Edit  /etc/sysconfig/iptables & above all REJECT rules paste:

  -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

  -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

  -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT

  /sbin/service iptables restart

  If everything restarts without any errors then:

  Continue to the testing phase

• Configuring Shibboleth SP 2 on CentOS to the ukfederation w/ Godaddy certs

  Date: 2009.10.27 | Category: certificates, janet, key, shibboleth, shibboleth2.xml, ssl, ukfederation | Response: 2

  Part 2. Shibboleth Config (6 hours)

  cd /etc/shibboleth
  wget http://metadata.ukfederation.org.uk/ukfederation.pem
  wget http://metadata.ukfederation.org.uk/ukfederation-metadata.xml
  

  Edit shibboleth2.xml

  Replace all instances of sp.example.org with your Entity ID ie sp.yourdomain.com

  Search for ApplicationDefaults

  Add homeURL=”https://sp.domainz.com/ahomeurl” under entityID – homeURL is the first url of the resource if none is specified.

  Search for <sessions

  Before the default example (Reading Default example directs to a speci… ” Insert:

  <SessionInitiator isDefault="true" id="UKFederation" Location="/WAYF/UKFederation"
  type="WAYF" defaultACSIndex="5"
  URL="https://wayf.ukfederation.org.uk/WAYF"
  />
  

  Search for exportLocation

  Under exportLocation replace http://localhost with https://localhost

  Replace all instances of root@localhost with the technical support email address

Search for MetadataProvider

This bit gets messy so pay close attention…..

Search for the line Delete it or comment it out.

Directly below it paste the following:

/etc/shibboleth/sp.key /etc/shibboleth/sp.crt

For now we are done in shibboleth2.xml

Run ./keygen.sh to generate your new key pair

mv sp-key.pem sp.key
mv sp-cert.pem sp.crt

Now we must configure Apache for shibboleth
