There is a solution while using Apache as webserver. http://trac.edgewall.org/wiki/TracOnWindows/Advanced#AuthenticatingTracusersagainstMSWindowsdomaincontroller
How to do this with TracStandalone?
Thanks~
I don't think that you can do that with the built-in tracd. It's a lightweight server designed for test and development. For production purposes, it's only suitable for users with basic needs. Anything as complex as authenticating with a Windows domain is going to need a full-featured web server like Apache that is more powerful and more configurable.
