Aaand of course I made a mistake :O when you're using virtual resources you
have to realize them somewhere, e.g.:
class all_users {
@user {"joe":
ensure => present,
...
groups => $servertype ? {
webserver => wheel,
default => $user_name
}
}
}
node 'mynode.local' {
$server_type = "webserver"
incldue all_users
realize(User["joe"])
}
Again, note that this is simplistic, you usually don't realize resources
directly in the nodes.

You should try re-organizing this so that you have your resources (here users)
defined in a class, e.g.
class all_users {
@user {"joe":
ensure => present,
...
groups => $servertype ? {
webserver => wheel,
default => $user_name
}
}
}
node 'mynode.local' {
$server_type = "webserver"
incldue all_users
}
This is a simpliest example, you may still use a define and have to watch out
for scoping rules, but that's the general idea.

I have tried this:
node 'mynode.local' {
$server_type = "webserver"
adduser { "joe":
server_type => $server_type,
user_name => "joe",
}
}
define adduser ( $user_name, $server_type ) {
realize User[$user_name]
realize Group[$user_name]
User[$user_name] {
groups => $server_type ? {
webserver => wheel,
default => $user_name,
},
}
}
@group { "joe":
ensure => present,
gid => 1234,
allowdupe => false
}
@user {"joe":
ensure => present,
managehome => true,
uid => 1234,
gid => 1234,
home => "/home/joe",
shell => "/bin/bash",
comment => "Joe",
password => '$1$ij21Zc04$MwyqTQP2fXc0BqMIjtz5b/',
}
When running puppetd on mynode.local I get this message:
notice: Ignoring cache
err: Could not retrieve catalog: Only subclasses can override
parameters at /etc/puppet/manifests/classes/adduser.pp:11
warning: Not using cache on failed catalog

I've been off for over a week, so I just noticed you never got an answer to
this question. The variables are filled out at the time the virtual resource
is defined, not at the time it's realized.
You might be able to do something like:
realize User[kenneth]
User[kenneth] {
groups => $server_type ? {
typeA => "wheel",
default => undef,
}
}
to realize it the way you want. Haven't tried anything like that though.
Maybe someone else can comment if it works.
