If you wish to try out this project, you are probably looking for the acegi-security-xx.zip file, which contains all of the officially released JARs, a copy of all documentation, and two WAR artifacts. The two WAR artifacts are from the Contacts Sample and the Tutorial Sample application. The Tutorial Sample consists of a "bare bones" configuration that will get you up and running quickly, whereas the Contacts Sample illustrates more advanced features.
Please note that in order to reduce download size, we only include in the release ZIP one of the WAR artifacts produced by the Contacts Sample application. The WAR artifact we include is suitable for standalone deployment (specifically, it does not require a CAS server, container adapter, X509 or LDAP setup). The official release ZIP therefore probably contains what you need, especially if you're initially evaluating the project. If you wish to deploy the other WAR artifacts produced by the Contacts Sample application (ie those that target CAS, container adapters, X509 or LDAP usage), you will need to build Acegi Security from source.
The acegi-security-xx-src.zip is intended for use with IDEs. It does not contain the files needed to compile Acegi Security. It also does not contain the sources to the sample applications. If you need any of these files, please download from SVN.
The official release ZIP files are available from the Sourceforge File Release System.
The Acegi Security JARs are also available via the iBiblio Maven Repository.
Detailed instructions on downloading from CVS and building from source are provided on the Building with Maven page.
If you don't wish to access SVN directly, we provide nightly SVN exports for your convenience. There is also an automated build which uploads bundle of Acegi Security jar files to the same location. Both binary and source archives have the date of the build and the SVN revision number appended to the filename, so you can match them up easily.
