Found one interesting observation today after switching to the new AD authentication. My ability to use password-less login via SSH suddenly went missing. Although I haven't fully resolved it yet (which I suspect may take regeneration/proliferation of keys), it would appear that I've been the victim of case sensitivity. In my old passwd file I had my user ID present in all lower case, but apparently in Active Directory my user ID is present as upper case. I am still able to make it log password-less using
ssh u012356@cr but ssh cr does NOT work, because my user ID is defaulting to U012345 (upper case U). In this case, however, I can STILL log in if I enter my password. I don't really think there is anything to correct here, but just wanted to point out the oddity in case anyone else suffers from a similar issue. Dave
