Regarding the failure to create a new profile, I believe that I had ETH00 configured with an IP address. As a matter of fact, I was using the browser configuration when creating a new profile.
I found a workaround by using a previous beta14 install. I backed up the beta14 profile and recovered it in beta16 with no problem. I then was able to modify it as if it was created on beta16.
I’m not sure if this will help you in determining where the bug is but it was able to get me past the ldap failure.
Yes. Using beta14 is OK for profile creating.
