Dave, Doug Leavitt, Frank, et al,
Doug, does it offer any substantial benefit to allow the user to configure all of DNS+NIS+LDAP (as opposed to only DNS+NIS and
DNS+LDAP discussed below)?

In order to provide more than one name service in the text installer/SCI

this rough draft.
Change name service selection screen, (which presently allows the user
to choose only one among DNS, LDAP, NIS, or None):
offer check boxes instead of a single selection. The user will be
subsequently prompted for configuration of whichever name services were
checked.
It's not clear that a DNS+NIS+LDAP is required, or even sensible. I'd like Doug and the naming team's feedback there. DNS+NIS or
DNS+LDAP is known to be useful, which is what I'd suggested initially.
The intent of offering the checkbox list was not to expressly include support for DNS+NIS+LDAP, nor was it disregarding your initial
suggestion, but it seems cleaner from a UI standpoint to have the user check the desired services and later be prompted for
information related to that service, while allowing detailed source definition.
Closer to your suggestion, consider this modification to the proposal:
Modify the Name Service selection screen as follows:
-------------------------
Name Service
Configure DNS?
Yes (default)
No
Configure a name service from the list below:
None (default)
LDAP
NIS
---------------------
Navigation for a text-based UI may be an issue here: if the user wants DNS + LDAP or NIS, what sequence must be typed to effect
this (without accidentally disabling DNS, that is)? tab, down-arrow? These could be separated on different screens for clarity.
Add another screen after all name service-specific prompting for the
user to enter name service sources, per nsswitch.conf(4).
I'm not a fan of adding this screen. I don't want to be in the business of full customization/management of nameservices, we
provide initial setup only because it's often necessary to get the system to operate reasonably correctly.
OK
If we're going to do anything with nsswitch, I'd consider just prompting for a profile URL rather than the default profile that
will be applied based on the previous selection.
This sounds nice. It does, however, rely upon networking to be up and could
not be effected by SCI tool directly.
Consider the following sources for svc:network/name-service-switch, adapted from an earlier suggestion from Dave (either not
displayed to user, or perhaps included on summary screen):
for LDAP + DNS:
default: files dns
printers: user files ldap
for NIS + DNS
default: files dns
printers: user files nis
Thank you,
William
