Bug#549858: openssh-server: Support AuthorizedKeysFile in Match block?

[Tollef Fog Heen <tfheen@debian.org>]

Package: openssh-server
Version: 1:5.1p1-7
Severity: minor

Hi,

it would be quite useful to be able to specify AuthorizedKeysFile in a
Match block in sshd_config.  The use-case is having different groups
whose ssh keys are distributed through multiple systems (think something
resembling userdir-ldap + puppet + manual copying).  We are currently
working around this by using AuthorizedKeysFile and AuthorizedKeysFile2,
but this doesn't scale beyond two locations and is a bit of a hack.
