pcache + LDAP_NO_ATTRS
I am using OpenLDAP 2.3.33. I run a slapd service using the pcache
overlay, which in turn queries another instance of slapd by means of
'database ldap'. It seems to work nicely for my simple use. I can
verify that query results are cached if the requested attribute
matches that of the "proxyattrset" directive.
However, I have a software which specifies LDAP_NO_ATTRS to the
attributes parameter of ldap_search_st(), as the software is
interested only in the presence of results, not their content. Is it
possible to instruct the pcache overlay, via "proxyattrset" or any
combination of other directives, to cache the results of such queries?
I have unsuccessfully attempted to define "proxyattrset 0", simply
omitting the attribute set. slapd starts fine, but does not seem to
cache my queries. It is unclear to me how slapd interprets this
I've failed to find any relevant information in the list archives or
google. Am I asking the wrong question? Is this simply an unnatural
use of the pcache overlay?
