Looking at the ITS history, it appears that this code was released in January 
2011 but in fact, the released code is not actually enabled. (It is behind an 
#ifdef LDAP_DEVEL mask.) Most likely a mistake was made in releasing it at 
that time, since I see no actual test feedback in the ITS.

If you want to test this you will have to compile back-meta yourself, and edit 
back-meta.h to make sure SLAPD_META_CLIENT_PR gets defined instead of being 
hidden. Please then send your test results as a followup to ITS#6664.
