Title: Don't leak LDAP server address when connection fails
Component: Setup
Level: 1
Class: Security fix
Version: 2.2.0i1
Prior to this Werk, trying to authenticate to an LDAP server that is unavailable would
result in an error saying that the server could be contacted.
This leaks the address of the LDAP server.
In addition, it was possible to check if a user is a htpasswd user, since the LDAP
connection is not attempted for these users and LDAP error is not shown.
Now a generic "invalid login" message is shown to avoid this information
disclosure.
