From d1d96fafe50b04395ff3ee4590777452e6612e02 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Fri, 1 Feb 2013 12:41:57 -0500 Subject: cifs-utils: add autoconf test to make sure that libwbclient is usable The idmapwb plugin requires a usable wbcSidsToUnixIds() function. Check to ensure that the wbclient library provides that symbol, and handle it appropriately if it doesn't. If someone were so inclined they probably could fix idmapwb to fall back to the older mapping functions if that symbol doesn't exist, but for now this patch just makes it refuse to build the plugin.
