What's the URL of the page containing the problem?
What steps will reproduce the problem?
1. Use active directory for auth via ldap
2. RB tries to do auth with anonymous bind
3. AD doesn't like that and fails
What is the expected output? What do you see instead?
This is a problem because with the LDAP auth, you can specify an email
domain. It is common for the email domain in an active directory to be an
internal only dns name. With the LDAP auth, that isn't a problem, but you
can't hit AD that way. With the AD auth, you can't specify the email
domain so you get bogus email addresses.
It would be a small step to specify an account for the LDAP auth.
