Redmine

I'm trying to get Redmine authentication working against OpenLDAP but login fails with an invalid user or password error. This is the configuration I have for the LDAP server:

Name: LDAP Server
Host: hostname.edu
Port: 636
Use LDAPS: Yes
Account: authuser
Password: password
Base DN: cn=users,dc=university,dc=edu
On-the-fly user creation: No
Login: uid
First Name: givenName
Last Name: sn
Email: mail

Testing the connection works just fine, but if I create a user with a valid LDAP uid as the Redmine login, no password, and LDAP server as the authentication method when the user tries to log in they get an invalid user or password error.

I did some searching and found some suggestions for trying different configurations for the account. I tried hostname/authuser and uid=authuser,cn=users,dc=university,dc=edu for the account and both of those had the same results - invalid user or password.

So I turned up logging to debug to see if I could get any errors but there aren't any in the logs. The interesting thing is that it looks like the LDAP authentication process should show up in the logs if logging is set to debug but there's nothing at all, so I don't think the authentication process is even hitting the LDAP server. All that shows up in the logs is this:

The instance I'm trying to get set up is running on Apache 2 on a Linux server through CGI, but I've tried the same setup on my local machine (Mac) using WEBrick and get the same results. Here is the output of script/about:

Ruby version 1.8.7 (i686-linux)

Does anyone have any suggestions for things I could try to figure out what the problem is? Thank you very much.
