Redmine

Good morning. We're looking to use Redmine for a few projects and to avoid giving our developers another username/password we would like to take advantage of the LDAP support. We're on a Windows network with ActiveDirectory/Exchange; your typical corporate environment. But all of our LDAP settings are a complete unknown and the odds of getting these settings from IT are slim to none (it's a very strict environment).

Another tool I'm running for SVN repo management handles authenticating against our domain out of the box and it doesn't appear there's much magic too it so I would imagine Redmine could do the same but maybe I just don't know where to look?

So as far as LDAP server settings go, what would be my best bet for discovering a server for Redmine to authenticate against? Any thoughts?

Thanks!
