caching results in back-ldap

[Stephen Brandon <stephen@brandonitconsulting.co.uk>]

Hi,

I'm writing a custom backend based on back-ldap, and am trying to squeeze all 
the performance out of it that I can.

I would like to use ldap_enable_cache (I know it's said to be soon 
deprecated, but for my purposes it should be ideal), but it seems that each 
connection made to the remote server is done with a different LDAP handle.

I can't find the place in the code that deallocates the old one, so I thought 
I would ask here if there's a particular reason why back-ldap does not seem 
to re-use its connections.

Any pointers appreciated.

Cheers,
Stephen Brandon
