Puppet does not allow two declared resources having the same type and the
same name or title. In your case, you get multiple declarations when two
users are assigned to the same group because you (re)declare the group for
each user assigned to it. Thus, the solution is to move the group
declarations outside your accounts::virtual definition. If you wish, you
can use virtual resources here, too, to avoid assigning unneeded groups to
the target node. Example:
class accounts::groups {
Group { ensure => present }
@group {
'group1': gid => 1234;
'group2': gid => 2345;
#...
'groupN': gid => 6789;
}
}
define accounts::virtual($group,
#...
) {
include 'accounts::groups'
user { ${title}:
ensure => present,
gid => $group,
require => Group[$group],
# ...
}
realize Group[$group]
# ...
}
If you have many distinct groups, however, then you will likely find that
it is easier and safer to record them in an external file instead of
modifying your manifests every time you want to manage groups. This is
what hiera() is for. It can be used directly or via Puppet's automatic
data binding mechanism to feed data to Puppet, such as all your (group
name, gid) pairs.
