Overview

This page will guide you through building and installing Cosign on Mac OS X. For additional notes regarding an installation on Mac OS X Server, please see Leopard Server Install.

Building and Installing

Requirements

You will need to have the current Xcode Tools installed. Download them from Apple's developer site or the Mac App Store. These notes also assume you have Apache 1.x or Apache2 installed. Recent Mac OS X releases include Apache2.

Get the Source

Download the latest release of Cosign from weblogin.org.

Configure the Build

In Terminal, decompress the archive and change to the Cosign source directory:

tar zxf cosign-VERSION.tar.gz
cd cosign-VERSION

If building for Apache 1.x, use --enable-apache1=/path/to/apxs. If building for Apache2, use --enable-apache2=/path/to/apxs2. If building for Mac OS X Server, you'll probably want to add --enable-universal-binaries, which will give you four-architecture (i386, x86_64, ppc, and ppc64) binaries of the daemon, CGIs, and the Apache filters.

./configure --enable-apache2=/usr/sbin/apxs --enable-universal-binaries \
	--enable-krb --with-gss

NOTE: For Mac OS X 10.7 Server, you can not build universal binaries, so the command would be:

./configure --enable-apache2=/usr/sbin/apxs --enable-krb --with-gss

Build the Apache Filter

make

NOTE: For Mac OSX 10.8 Server, XCode 4.4 (as of it's first release in July 2012) has a bug where a compiler path is missing. Before running "make", you will need to do this:

cd /Applications/Xcode.app/Contents/Developer/Toolchains

sudo ln -s XcodeDefault.xctoolchain OSX10.8.xctoolchain

Running "make" at this point will generate a lot of "deprecated" warning messages -- these can be ignored when installing cosign 3.2.0 (as of August 2012)

Build All Weblogin Components (Optional)

If you intend to set up a weblogin environment, you'll need to build the daemon and CGIs:

make everything

Install

make install

or

make install-all

if you're setting up a central weblogin server.

Create Support Directories

The cosign filter, [mod_cosign], by default stores service cookies in /var/cosign/filter. You can override the location of the service cookie directory using the [CosignFilterDB] directive, but the default location is fine for most uses. The directory must exist, and the Apache user, www, must be the owner of the directory:

sudo -s
Password:
root# mkdir -p -m 0750 /var/cosign/filter
root# chown www:www /var/cosign/filter

Next Steps

At this point, you should have all the pieces in place. For instructions on configuring Cosign with Apache, please see these instructions. The Leopard Server Install, Lion Server Install, and Mountain lion server install notes, although focused on the University of Michigan's environment, should help get you up and running on Mac OS X Server. This page describes setting up a complete weblogin environment.
