I’ve got my OD credentials stored in the browser. (I frequently switch between my general user account, our admin account, and the production account.) But when the browser fills in the password for me, OD complains: “There was a problem with your request. Please provide a password.” I guess there is some JavaScript event you’re looking out for, that fires only when the user types in a password and not when the browser fills it in.
This is not a huge problem, just a minor but frequent annoyance for us.
(The workaround is easy; I just type a space after the auto-filled password and delete it again. I can then log in.)
