If the user check DNS, LDAP and NIS, how do the user express their preference to
search LDAP first, then, DNS, then NIS?
The order would be defined in the name service switch screen; the sources on 
the left are referenced first.


Add another screen after all  name service-specific prompting for the user to 
enter name service sources, per nsswitch.conf(4).
Like Dave, I don't think it is a good idea to add another screen to manage 
entries in the nsswitch.conf file.
It's difficult to provide a user friendly interface to modifying the 
nsswitch.conf file in the UI.
The purpose would be to allow the user to be explicit in the case of multiple 
name services, as above.

I think that the focus in such a character-based UI would be on preventing the user from putting in unknown entries and making sure that the context is correct. This could be done incrementally - constantly re-evaluating as the user types.

But, sInce we are going to support only combinations: DNS+LDAP and DNS+NIS, and we have an acceptable standard default name-service/switch configuration, so we can avoid this screen and allow users to define sources more specifically later.

Thanks for the feedback,
William
