OpenLDAP authentication: Invalid user or password
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.
Redmine 1.0.1 - Redmine 1.0.5
Redmine 1.1.1 BitNami stack
For information, my OpenLDAP server is configured as a metadirectory (accounts are stored in two Active Directory servers)
