Issue #1674 has been updated by rgsteele.
Below are the classes and definitions used to reproduce this problem. And,
according to the TypeReference, arrays are only needed when specifying multiple
groups (
# Class which realizes the user
class dev_userconf {
realize( Group["alpha"], Group["tango"], Group["charlie"], Group["bravo"] )
realize( User_account["foo"] )
}
# Class which passes some user attributes to the user_accts
# virtual define. Start out with this, then after the client
# runs once, change the 'groups' to: ["charlie", "bravo"], or
# even just ["bravo"] - any array will throw an exception.
class user_accts {
@user_account { "foo":
comment => "Foo Bar",
type => "dev",
groups => "bravo";
}
}
# The virtual definition
define user_account ( ensure = present, type, comment, shell = false, groups =
false ) {
# Define the appropriate shell and supplementary groups
case $type {
dev: {
$supp_groups = $groups ? {
false => ["alpha", "tango"],
default => ["alpha", "tango", $groups]
}
$user_shell = $shell ? {
false => "/bin/bash",
default => $shell
}
}
nondev: {
$supp_groups = $groups ? {
false => "charlie",
default => ["charlie", $groups]
}
$user_shell = "/sbin/nologin"
}
}
user { $name:
ensure => $ensure,
groups => $supp_groups,
comment => $comment,
shell => $user_shell,
}
}
Also worth noting is even if you start out with an array for the 'groups'
attribute, if you ever switch to using a single string, you can never switch
back.
----------------------------------------
Bug #1674: Puppet compares string to array if 'groups' attribute of user type
is changed accordingly.
http://projects.reductivelabs.com/issues/show/1674
Author: rgsteele
Status: Accepted
Priority: High
Assigned to: andrew
Category: user
Target version:
Complexity: Unknown
Affected version: 0.24.5
Keywords:
If the 'groups' attribute for a user is first stored as a string, but then
later changed to an array, Puppet throws an exception and complains that it
can't compare a string to an array. Here's a trace:
