Redmine

I have a CentOS 5.3 system installed with: ruby 1.8.6, rubygems 1.3.1, rails 2.1.2, rake 0.8.3, the mysql gem and Redmine 0.8.5.

I have the LDAP authentication page setup to point to our Windows AD server on the std port 389, with a valid Account and password since we don't allow anonymous searches/binds. Also the 'on-the-fly user creation' button is checked -
Base DN: dc=engineering,dc=my-company,dc=com
Login: sAMAccountName
Firstname: givenName
Lastname: sn
Email: mail

The 'Test' link works OK, but when I attempt a login I get 'Invalid user or password' error. Below is the output in the production.log:
-------------------

--------------------

The text after "login"=> in the log looks curious and different than other output I've seen in other posts. Usually the login name is repeated here.

Any suggestions on how to further troubleshoot this would be greatly appreciated.
