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

Part 4. Testing (2 hours)

Shibboleth can be started using /sbin/service shibd start
Another option is to use: service shibd restart
If the above doesn’t work try /usr/sbin/shibd -f

If you are going to use different commands to start shibd ensure that multiple copies are not running by doing ps aux | grep shibd

If you see shibd -f & /usr/sbin/shibd….. then you need to kill them and start one. I recommend using service shibd start.

Log files will be in: /var/log/shibboleth/

Check the shibd.log file for errors using this command: cat /var/log/shibboleth/shibd.log | grep ERROR
Your resource URL is https://shib.yourdomain.com/secure
Try browse to it.
If you get nothing then Apache hasn’t started properly, check the apache logs.
You should get something that starts with the shibboleth logo OR a WAYF login screen.
If you get the WAYF screen the things are going great, if you get the Shibboleth error message then we need to make some more configuration changes. See your logs and continue reading.
If you get “Cannot connect to shibd process, a site adminstrator should be notified.”
then your SELINUX restrictions have kicked in. Check by doing
cat /var/log/audit/audit.log | grep shib

More info on SELinux can be found here or by using the sestatus command:

A good output should look like this:
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: permissive
Mode from config file: enforcing
Policy version: 21
Policy from config file: targeted

The fix for the SELinux problem is documented on Page 1 however I recommend being a bit more brutal if your environment is hyper fussy about security.

Once you have a working setup you can browse to http://shib.yourdomain.com/Shibboleth.sso/Metadata to get your automatically generated Metadata and proceed with the UK Federation registration process.
When you speak to the UK Federation to approve your registration you will be asked to run this command from /etc/shibboleth
openssl x509 -sha1 -in sp.crt -noout -fingerprint

You will be asked to provide them with the fingerprint so keep a record of this.
Griffin goes “meow”.

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

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

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

SSLCertificateFile /etc/shibboleth/external.crt
Under SSLCertificateKeyFile paste SSLCertificateChainFile /etc/shibboleth/external_int.crt
Edit /etc/httpd/conf/httpd.conf
 UseCanonicalName Off
 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

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" 

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
<MetadataProvider type="XML"


backingFilePath="/etc/shibboleth/ukfederation-metadata.xml" reloadInterval="14400">

<MetadataFilter type="RequireValidUntil" maxValidityInterval="2592000"/>

<SignatureMetadataFilter certificate="ukfederation.pem"/>


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
