In libraries/libldap/options.c, an ldap_set_option() on the
LDAP_OPT_NETWORK_TIMEOUT currently provides a nice way to set a timeout on the
initial client attempt to connect() to the server.  However, there is no
corresponding code in libraries/libldap/init.c which would allow a system
administrator to set that value using ldap.conf.  Allowing the sysadmin to set a
very short timeout would be extremely useful in the case of a site with
redundant LDAP servers, in that the failure of the first listed in the URI
variable would not result in long lags for client systems.

I've written a trivial patch to init.c, creating the variable ldap.conf variable
NETWORKTIMEOUT, which provides the above-described functionality.  My patch also
includes a small edit to doc/man/man5/ldap.conf.5, which describes the variable,
and contrasts it with the existing TIMELIMIT variable.  The patch available at

and is against the cvs HEAD of openldap-src as of a few minutes ago.
