Description

I configured LDAP authentication using ActiveDirectory.

Users are able to log in by their username/password, but they also can log in with empty password.

If they enter wrong password (which is not an empty string) they got the "Invalid user or password" message.

I think the problem is in ruby-net-ldap. It is used in /app/models/auth_source_ldap.rb around line 50:

# authenticate user
ldap_con = initialize_ldap_con(dn, password)
return nil unless ldap_con.bind

ldap_con.bind returns true when empty string was given as password.

Redmine version: v0.6.3
ruby-net-ldap version: 0.0.4

I can not reproduce this problem with openldap. Anyway, the fix is committed in trunk (r1169) and 0.6 branch (r1170).

0.6.3 users can apply this patch to fix it:
