comment Trying to add a new SQL Server user throws the error "is not a valid login or you do not have permission”
This question has the same error message as this other question, but happens during normal administration rather than during installation. It looks like there are different causes and answers, so I'm posting this as a separate question.

comment What are the exact protocol level differences between SSL and TLS?
It looks like the TLS Extensions only apply to TLS and not SSL, correct? So, for example, TLS clients may send an extended 'ClientHello' record, while SSL3-only clients would only ever send the original 'ClientHello'.

comment EC2 SSH Prompting for Password
@IanCarroll As for your question, I agree with mgorven; the server is asking for a password because keyfile authentication has failed. 1. Does your current user own the key file? sudo chown {currentusername} {filename.pem}. 2. Have you successfully ssh-ed into this machine before? 3. can you verify that .ssh/id_rsa is the correct key to connect to this server? (do you have other keys?)

@IanCarroll But do Amazon-supplied AMIs definitely copy down keyfiles from AWS? If so do you have a reference for that? I can't seem to find it explicitly mentioned in the documentation.

comment EC2 SSH Prompting for Password
@mgorven What do you mean by "check that the AMI installs SSH keys"? Do some AMIs do that while others do not? Is there a list of which ones install keys on startup?
