Upgrading systems configured to use ldap via ssl as the first service in the nss stack (in nsswitch.conf) leads to a broken nss resolution afterwards (for example sudo would stop working). A workaround is to configure ldap to be used after the compat service in nsswitch.conf before the upgrade is started.
