gentoo-overlay/sys-auth/nss_ldap/files/nss_ldap-252-reconnect-timeouts.patch

This patch changes the default timeouts, so that they are much lower, and do
not cause major delays when booting a system. This is a workaround until the
core /etc/{passwd,group} contain all of the data needed for a system boot.

Also add a note that 'ssl on' is broken and TLS should be used instead.
