Unless there is my case where I have just to update once a day
the balance from upstream and only be able to read it, not update it. 

Second: it doesn't have to be _maintained_ by the ldap server,
just to be _read_! I.e. I assume one could have a DB in the backend
and use LDAP just to _read_ the values. But in order to be able
to read the values trough the LDAP protocol it must have a schema
entry somewhere. At least this is my understanding.

Third: in a "one master, several slaves" only the masted may be
allowed to update the records so the problem of write concurrency
does not exists.

Could somebody tell me please if I am wrong and why ?
