Hi Michael. The reference for this syntax is at
http://reductivelabs.com/trac/puppet/wiki/VirtualResources (linked from
http://reductivelabs.com/trac/puppet/wiki/LanguageTutorial#virtual-resources).
The docs say that virtual resources are supported since 0.20.0, but they
don't say whether the "collection" syntax ( <|...|> ) is supported since
then-- maybe it's more recent. I'm running 0.25.4, so it's possible that
you need a more recent version of Puppet than 0.24.8 to use ssh::auth.
If someone can clarify what Puppet version is required for the collection
syntax, I'll add it to the list of requirements of ssh::auth.

No, that's not correct. To realize a virtual resource, you have to use
either the collection syntax, as in ssh::auth; or the realize function:
realize Ssh_auth_key_client[$title]
which, according to the docs, doesn't seem to support adding parameters,
e.g.
realize Ssh_auth_key_client[$title]{ ensure => $ensure }
However, in my testing I found that the above does in fact work, but only
if the parameters inside the brackets haven't been set yet. That makes it
not useful for ssh::auth, where the purpose is to override defaults. It's
also undocumented.
If the collection syntax makes ssh::auth unusable in Puppet 0.24, I'd
gladly change it to something more compatible. But because of the
limitation of the realize function, I can't see a way to do that right now.
Andrew.
