Re: (ITS#4059) The 'nretries' parameter in back-meta configuration

[ando@sys-net.it]

This portion of back-meta (and back-ldap) is a work in progress; the code
is being changed frequently based on the results of the experimentation
we're conducting.  The current setup seems to represent a robust and
reliable compromise between performances and failover on the different
platforms we're using right now.  If no more changes occur, I'll take this
ITS as a reminder of lining up the man page.

Thanks, p.
