Mac OS X Identity Services plugin

A Redmine plugin for authenticating with Mac OS X Identity Services.

  • User groups in Redmine can be linked to groups in a directory service

  • User membership in groups is update each time a user authenticates

  • Access can be restricted to just those users who belong to defined groups
