Hi,

As a follow-up from https://bugs.openldap.org/show_bug.cgi?id=10373, it appears that the configuration I had shared can be converted to olc with slaptest, however does not pass validation be loaded when the daemon start:

``` $ slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d $ slaptest -u -F /etc/openldap/slapd.d -d stats -d pcache unrecognized log level "pcache" (deferred) Total # of attribute sets to be cached = 16.

From the following slapd.conf:

``` overlay pcache pcache mdb 65536 16 1024 60 directory /var/lib/openldap-data/pcache pcacheMaxQueries 1024

The following olc configuration get generated

Is this a known limitation at the moment ?
