New docs on these topics are available at http://allura.sourceforge.net/docs/scm_host.html (thanks Dave Brondsema!). Topics include:
1. Setting up basic Git/SVN hosting services with your Allura installation. 2. Setting up an ssh-based configuration of Git/SVN/Hg, with repos isolated in a chroot jail, authenticating against LDAP and authorizing via an Allura API. 3. Configuring Allura to authenticate against LDAP. (Sorry for the cross-post but I think this is relevant to both Allura developers and users.) -- Tim Van Steenburgh
