[PATCH] Add alias to authorization config

[Sander Striker <st...@apache.org>]

Hi,

I'd like to add alias functionality to the authorization
configuration.  This is primarily useful in combination with
doing client certificate authentication.  You can refer to a
cert subject using &alias, instead of having to replicate it
in multiple places.

An example illustrates this best, but you have to imagine doing
this when you have a bit more than one cert:

[aliases]
striker = /C=US/ST=ExampleState/O=Example Inc/L=ExampleTown/OU=example/CN=Sander Striker/emailAddress=striker@example.com

[groups]
group = &striker,

[/]
* = r
&striker = rw

[/foo]
@group = r


If I hear no objections, I'll commit this trivial change tomorrow.


Sander
