I have a review in MozReview: https://reviewboard.mozilla.org/r/30087/ The autoland/try options in the dropdown are disabled for me, with a tooltips "You do not have the required scm level to trigger a try build" & "You must have scm_level_3 access to land". This originally made me think my account had been disabled, because I've been on leave for some time. But nope, my account is all good (see bug 1238255). However, I did push to the MozReview repo via HTTPS (because pushing there via SSH won't work for me, bug 1096126). So I wonder if that's related.
That's exactly the problem, the association between your account and your ldap credentials is made when you push via ssh. We're planning to fix this (see Bug 1239815) - I'll leave this bug open as well since it's a lot easier for people to find when searching.
