Replication with database-backend

[Luzian Scherrer <lsc@zi.unizh.ch>]

Hello,

When using the database backend (slapd-sql), how does one incooperate
replication for data that gets edited directly in the database and not
through the master server? Is there a way to accomplish this with
OpenLDAP?

I'm trying to find a good solution to present an already existing
database of user-information via LDAP. Reliability is definately
important for this application; a single master server depending on the
database does not satisfy the requirements in this case.

One possible solution would be to use caching LDAP servers instead of
slaves. These could forward the requests to the master or, if the
master is not available, answer from their own cache. Do you think the
effort would be justifiable trying to modify OpenLDAP to function as
such a cache or is there simply a better solution?

Thanks,
