Redmine

It seems that Redmine versions > 1.0.0 have a problem with OpenLDAP. I've configured LDAP authentication with valid settings (works on 1.0.0) on Redmine 1.0.1, 1.0.5, 1.1.1 and my attempts failed with a "Invalid user or password" message. I did further tests with Active Directory servers, all of them allowed me to authenticate. So I really think that it's related in some way to OpenLDAP.

Setup 1-2:

Redmine 1.0.1 - Redmine 1.0.5
Rails 2.3.5
Ruby 4.5
MySQL 5.1

Setup 3:

Redmine 1.1.1 BitNami stack

For information, my OpenLDAP server is configured as a metadirectory (accounts are stored in two Active Directory servers)
