Re: db/schemas best practice
But I wasn't really asking for advice on architecture design. :-)
Last time I looked you couldn't bind Outlook or any other LDAP client
to a relational database for contact into.
I'm trying to determine OpenLDAP's capabilities for handling multiple
backends and what the implications are to those backends when you make
a change to a shared schema.

I am developing something which stores contact data for multiple
'clients' (i.e., discrete businesses).
My theory based on the FAQ response is to partition off each client,

My 2 questions assuming this is OK are:
1) How many backends can slapd deal with before needing to move to a
new process or server (none of these clients will have more than
probably 10,000 entries).
2) Some of the clients have custom attributes they want to have in
there like for example and auto dealer may want to have a vehicleMake,
vehicleModel and vehicleYear attributes so they can have that
information associated with their customers entry. What I have
currently is a schema that is shared by these backends and this seems
to work fine. But if/when a new client comes on and I need to add an
attribute, does this "break" existing clients data? The existing
clients wouldn't be accessing or using these new attributes. Or do I
have to dump and restore every backend when I make a change like that.
Would a better approach be to have a schema for each client that
new entries. The schema attributes are "generally" industry related
so if I have 10 auto dealers, they'll all basically have the same
requirements so they can be shared to some extent.
Any advice is appreciated.
