This determines which ldap field is used as the username on
HackMD. By default, the "id" is used as username, too. The id
is taken from the fields `uidNumber`, `uid` or
`sAMAccountName`. To give the user more flexibility, they can
now choose the field used for the username instead.
Documentation added in aaf034b on Nov 17th 2016 says the S3 bucket can
be specified with `s3.bucket`, but commit c8bcc4c (#285) on Dec 18th
2016 used `s3bucket`. Instead of fixing the code (#552) to match the
documentation this commit changes just the documentation so that
existing configurations are not broken. Also, the `s3` object is passed
as is to `AWS.S3()`, which does not know the option `bucket` (but
silently ignores it in my test).

Following the old documentation leads to this exception:
