Subject [jira] [Commented] (ACCUMULO-3736) Underscore in password causes problems
Date Thu, 16 Apr 2015 17:15:58 GMT


Christopher Tubbs commented on ACCUMULO-3736:

bq. I would've thought ascii-range characters would be pretty bulletproof...

Yeah, that's what I would have thought, but I have no idea what platform encoding he might
have been using when this occurred. For all I know, it wasn't an actual ASCII underscore,
but some other underscore-like character, copied and pasted from another application with
a different encoding.

I just created the issue so it wouldn't be forgotten. I haven't had a chance to investigate
or verify.

>            Reporter: Christopher Tubbs
> A user reported that they were unable to authenticate to Accumulo (1.4.x) after setting
a password which contained an underscore.
> Steps the user performed:
> # Create new user in the shell using root
> # Set password, containing underscore on this new user
> # Switch to that user in the shell, it worked
> # Log in to the shell directly, using "-p" on the shell's command-line did not work
> # Using the Java API did not work
> The failure was "BAD_CREDENTIALS".
> I suspect he experienced some strange platform encoding issue with how we serialize passwords
to byte arrays internally, but this needs further verification (especially to check to see
if it applies to more recent versions).
