RFC: -server packages universe demotions and main promotions

Since demoting NIS seems to be decided, I decided to give LDAP a try.
(Please do not read this message as a flame.
Read it as one sysadmin's reaction on migrating
to LDAP, but I think that my reaction will be a common one.)
What a pain to use! Practical documentation is hard to find. There is lots
of information about the LDAP protocol, but not much in the way of how to
replace NIS with LDAP.
The integration between NIS and the system is much tighter than LDAP.
With LDAP, everything seems to be grafted on, requiring special handlers
for autofs, dovecot, etc.
NIS is designed to provide the existing system information to network
clients, so support scripts create information maps from the standard
system files. LDAP is a repository, so support scripts are confused
between preserving the existing repository, versus updating with current
IMHO, I think sys admins would be tempted to rsync config files (passwd,
shadow), instead of slogging through LDAP configuration.
