Yes, "gazillion ways" that also was my impression and the aim of this 
inquiry is to reduce the number of configurations to try and discard. ;)

Samba4 is aimed at a SSO solution for the network. There as many Linux 
systems as Windows on the net. Most Windows systems however are not 
joined - these are Win## Home licenses. Currently most of them print 

I have Laptops, which are neither joined and neither get their user 
information from LDAP, but when connected locally will be able get 
tickets from the DC (at least the linux boxes). They also will access 
file shares similar to WinXP Home systems.

So in short: Whoever has permission to print can get a Kerberos ticket 
or mount a file share. There are no anonymous file shares.

Hope that helped to outline the context for the best pratices.

Thanks for your help,
