Installing SP2.x under MacOS

This page is still _very_ much a work in progress.

Installing/Configuring Shibboleth for OS Server 10.5.6

Install MacPorts & Shibboleth

Download Mac Ports from http://www.macports.org/install.php and install the .pkg

Open Terminal and type:

sudo port install curl +ssl

sudo port install shibboleth

The installation of Shibboleth and supporting software will take some time.

Retreive the Shibboleth profiles

cd /opt/local/

sudo curl http://shibboleth.internet2.edu/downloads/shibboleth/cppsp/latest/mac/ports.tar | tar xv

Edit /opt/local/etc/macports/sources.conf and add in:

file:///opt/local/ports	[nosync]

before the line:

rsync://rsync.macports.org/release/ports/ [default]

This enables Mac Ports access to the non-standard software repository containing Shibboleth.

For first time installs only

cd /opt/local/etc/shibboleth

ls -1 *.dist | sed -e 's/\.dist//' | xargs -I % sudo cp "%.dist" "%"

sudo sh ./keygen.sh

As the default permissions for the cert files causes Shibboleth to fail they need changing:

sudo chmod 740 sp-key.pem

sudo chmod 644 sp-cert.pem

Disable Intel 64 bit architecture for Apache

Shibboleth is currently not compatible with the 64 bit architecture available on some newer Macs. To check run the folling command in Terminal:

sysctl hw.optional.x86_64

If the result is 1 then do the following steps, otherwise skip to the 'Create the Shibboleth log file' section

sudo emacs /usr/sbin/apachectl

change HTTPD variable from:

HTTPD='/usr/sbin/httpd'

to:

HTTPD='arch -i386 /usr/sbin/httpd'

Add the following 2 lines to the <array> element in /System/Library/LaunchDaemons/org.apache.httpd.plist:

<string>arch</string>
<string>-i386</string>

The array element should look like this when done:

	<array>
                <string>arch</string>
                <string>-i386</string>
                <string>/usr/sbin/httpd</string>
                <string>-D</string>
                <string>FOREGROUND</string>
        </array>

Create the Shibboleth log file

sudo touch /opt/local/var/log/httpd/native.log

sudo chown _www /opt/local/var/log/httpd/native.log

Ensure SSL is enabled for the website

Using Server Admin select Web | Sites pane, choose the website and enable SSL from the security tab

Configuring Apache

Add the following to the /etc/apapche2/httpd.conf file:

Include /opt/local/etc/shibboleth/apache22.config

If you are not using apache v2.2 then edit the above line appropriately according to the contents of the /opt/local/etc/shibboleth/ directory.

Ensure that the ServerName directive is set correctly and UseCanonicalName is set to On

Download the Shibboleth configuration templates

cd /opt/local/etc/shibboleth/

sudo curl http://raven.cam.ac.uk/project/shibboleth/files/config/shibboleth2.xml-UCAMSKEL -o shibboleth2.xml

sudo curl http://raven.cam.ac.uk/project/shibboleth/files/config/attribute-map.xml-UCAMSKEL -o attribute-map.xml

sudo curl https://shib.raven.cam.ac.uk/ucamfederation-idp-metadata.xml -o ucamfederation-idp-metadata.xml

Edit the config files and look for the FIX-ME flags highlighting required edits to the files. See https://wiki.csx.cam.ac.uk/raven/Shibboleth_documentation_and_HOWTOs#Deploying_Shibboleth_SPs_in_the_University for more info.

Starting the service

Set shib to load at startup:

sudo launchctl load -w /Library/LaunchDaemons/org.macports.shibd.plist

Start Apache:

sudo apachectl start

Test your page!

Reloading the service

Any changes to the shib config will require both shibd and apache to be reloaded:

sudo launchctl unload -w /Library/LaunchDaemons/org.macports.shibd.plist

sudo launchctl load -w /Library/LaunchDaemons/org.macports.shibd.plist

sudo apachectl restart

You may care to script this to save your sanity when making lots of changes/testing..
