[horde] turba separate LDAP write and read servers ?

[Andy Dorman]

We are transitioning from an ancient Horde/Imp/Turba set up to the 
latest debian release (turba 4.2-beta1 currently on our dev server).

We use OpenLDAP for authentication and the turba address book.  Our 
OpenLDAP is set up as a master-slave cluster with a local slave on each 
web server and only the master accepting writes.

Our old turba setup used the "write_server" setting to split reads to 
the local read-only slave server and send writes to the master.  This 
has worked well for several years resulting in lightning fast 
address-book searches in the email compose window.

I have just noticed that the latest turba backends.php does not mention 
a write_server setting and I have not found anything in the UPGRADING, 
LDAP, or INSTALL docs that mention it.

So is it no longer possible to use a separate write_server for Turba?

If this feature has been lost over time, we might be interested in 
paying a developer to add it for the community if it would not be too 
difficult.

Thanks for all your excellent work on Horde!
