+# We basically use nscd as a proxy for forwarding nss requests to appropriate

+# Note that we can not use `enable-cache no` As this will actually cause nscd
+# to just reject the nss requests it receives, which then causes glibc to
+# fallback to trying to handle the request by itself. Which won't work as glibc
+# is not aware of the path in which the nss modules live.  As a workaround, we
