This always seems like a nice simple idea in theory. The reality is
that you'd have to put so much complexity in to deal with stuff like
working out what to do during a restart if the LDAP server suddenly
stops responding (at the point where you have already thrown away the
old config). You also have to come up with (and hard-code!) some LDAP
schema; and have it extensible to third-party modules (i.e. generic
enough that it's just untyped key-value pairs again). And how do you
configure the LDAP connection: TLS, auth, etc? Just relying on the
system-wide defaults doesn't cut it for 99% of apps so why would it
here? And why only support an LDAP backend? Why not also an SQL
database, or a WebDAV repository?
So the reality is that rather than add all that complexity to 50
different daemons, it's better to go and write one single tool which can
create flat file configurations from LDAP databases, or SQL databases,
or whatever, and can know how to restart the daemons as necessary, and
can apply a consistent LDAP schema across the board, etc.
