Shibboleth WAYFless URLs UKFederation

Admin Admin — Tue, 27 Oct 2009 20:55:00 +0000

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 ?

Another example

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

https://wayf.ukfederation.org.uk/shibboleth-wayf/ukfull.wayf?target=cookie

&providerId=urn:mace:ac.uk:sdss.ac.uk:provider:service:target.iay.org.uk

&cache=perm&action=selection

&origin=https://idp.primarylogon.co.uk/idp/shibboleth

&shire=https://target.iay.org.uk/Shibboleth.sso/SAML/POST

The bits in bold need changing.

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

Admin Admin — Tue, 27 Oct 2009 15:37:00 +0000

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

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

After the line reading Insert
Search for the line Delete it or comment it out.

Directly below it paste the following:

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

Don’t forget to replace yourpassword with your key password if you have set one!

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
