Hi,
I've been working on extending the useradd/groupadd providers to allow 
local user management when duplicate names exist in a remote LDAP database.

I have the code complete which can be viewed here:
https://github.com/jjulien/puppet/compare/master...feature%237911

There has been some discussion about providing the libuser.conf file with 
this patch though.  So I'd like to bring that discussion up here and get a 
solution hashed out before I submit the pull request.  

Summary:
The useradd/groupadd commands will not add duplicate names in /etc/passwd 
if they find the account in LDAP.  The luseradd/lgroupadd commands are 
capable of this, so they are used to make sure the local accounts get 
managed in this patch.  luseradd/lgroupadd use /etc/libuser.conf to 
determine which create_module to use when creating accounts, its important 
for this patch that the modules used is "files".  If a system existed with 
an /etc/libuser.conf file that had ldap specified as a create_module it 
would produce undesired results from this provider.  However unlikely of a 
situation as that may be, it is a potential bug that could come up later if 
Puppet does not enforce a specific libuser.conf.  Luckily, libuser allows 
the configuration file, /etc/libuser.conf by default, to be overridden by 
setting the environment variable LIBUSER_CONF.  This is the reason for 
shipping the exact libuser.conf file needed by this provider with Puppet. 
 The placement of the file in lib/puppet/features/libuser.conf has been the 
main concern.  I'm definitely open to moving this, it would need to be in a 
place that could always be counted on and that the 
Puppet::Util::Libuser.setupenv module would be able to find through either 
hard coding, or relative pathing like it currently does.  

Please advise on the best way to handle this file.

Thank you!
