Yep I ran into this with an Oracle OpenAir. Needed to reset my password so I fire up 1Password, generate a 50 char PW and set that. It works for the first login but when I logout and log back in it tells me I have an incorrect password. Go through a password reset a few more times before I finally realize that they are just taking the first 12 characters of my PW and using that, and not telling me that they are doing that.
