Shibboleth as a Tool for Authorized Access Control to the Subversion Repository System

Linh Ngo, Amy Apon
University of Arkansas

Abstract—Shibboleth is an architecture and protocol for allowing users to authenticate and be authorized to use a remote resource by logging into the identity management system that is maintained at their home institution. With Shibboleth, a federation of institutions can share resources among users and yet allow the administration of both the user access control to resources and the user identity and attribute information to be performed at the hosting or home institution. Subversion is a version control repository system that allows the creation of fine-grained permissions to files and directories. In this project an infrastructure, Shibbolized Subversion, has been created that consists of a Subversion repository with an Apache web interface that is protected by a Shibboleth authentication system. The infrastructure can allow authorized and authenticated data sharing between institutions yet retains simplicity and protects privacy for users. In addition, it also relieves local administrators from the task of having to perform extra account management for users from other institutions. This paper describes the Shibboleth and Subversion systems, the implementation of the file sharing infrastructure, and issues of attribute maintenance, privacy and security.
