proxycache is an overlay, so it is supposed to have as little knowledge as
possible of the underlying database.  It can be used with any database,
although it mostly makes sense with back-ldap, back-meta, back-sql and so.
 The problem here is in back-ldap.  Recent evolutions of that database
required it to be allowed to start with an empty URI field, as under
special circumstances it may be generated from the request's data
(essentially in slapo-chain).  It appears that an empty URI means
"ldap://localhost/"; which may not be what you expect.  In any case, if
your proxy backend needs an URI to work correctly, you should first blame
yourself for not providing one...

Thanks for the report, p.
