> In Visibility Labels security, a set of labels (auths) are administered and associated
with a user.
> A user can normally  only see cell data during scan that are part of the user's label
set (auths).
> Scan uses setAuthorizations to indicates its wants to use the auths to access the cells.
> Similarly in the shell:
> {code}
> scan 'table1', AUTHORIZATIONS => ['private']
> {code}
> But it is a surprise to find that setAuthorizations seems to be 'mandatory' in the default
visibility label security setting.  Every scan needs to setAuthorizations before the scan
can get any cells even the cells are under the labels the request user is part of.
> The following steps will illustrate the issue:
> Run as superuser.
> {code}
> 1. create a visibility label called 'private'
> 2. create 'table1'
> 3. put into 'table1' data and label the data as 'private'
> 4. set_auths 'user1', 'private'
> 5. grant 'user1', 'RW', 'table1'
> {code}
> Run as 'user1':
> {code}
> 1. scan 'table1'
> This show no cells.
> 2. scan 'table1', scan 'table1', AUTHORIZATIONS => ['private']
> This will show all the data.
> {code}
> I am not sure if this is expected by design or a bug.
> But a more reasonable, more client application backward compatible, and less surprising
default behavior should probably look like this:
> A scan's default auths, if its Authorizations attributes is not set explicitly, should
be all the auths the request user is administered and allowed on the server.
> If scan.setAuthorizations is used, then the server further filter the auths during scan:
use the input auths minus what is not in user's label set on the server.
