[chef] Notifications and data

[Steffen Gebert < >]

Hi,

I have some trouble with "notifies".. hope it's easy to explain to a 
chef-starter :)

I've modified the "users" cookbook [1] to set an empty password and (usermod 
-p "") and forcing password change on next login (chage -d 0).

Therefore I've extended the cookbook inside the 
> search(:users, 'groups:sysadmin') do |u|

loop with the following block:

>   script "set_empty_password" do
>     interpreter "bash"
>     user "root"
>     action :nothing
> 
>     code <<-EOH
>     echo Running for #{u[:id]}
>     # set empty password
>     usermod -p "" #{u[:id]}
>     # force password change on next login
>     chage -d 0 #{u[:id]}
>     EOH
>   end


To notify it upon user creation, I've added
> notifies :run, "script[set_empty_password]", :immediately

to the following block:

>   user u['id'] do
>     uid u['uid']
>     gid u['gid']
>     shell u['shell']
>     comment u['comment']
>     supports :manage_home => true
>     home home_dir
>     notifies :run, "script[set_empty_password]", :immediately
>     notifies :create, "ruby_block[reset group list]", :immediately
>   end


My problem, however, is that in the bash script, #{u[:id]} is always the user 
name of the user returned as *last* from search (so for every user it always 
modifies the same one). set_empty_password is executed, but with wrong data..

I've uploaded the complete file here:

Can you tell me the reason for this?

Thanks a lot for your help!
