@lslebodn I am not sure about that. Maybe we could document the fact
that it has significant performance impact? Retrospectively, I think we should do this
also for SSS_NSS_USE_MEMCACHE. It may be obvious to some people, but stressing it out is
SSS_NSS_USE_MEMCACHE is a different case. Because you intentionally disable it
per client. Disabling memcache globally on heavy load server (e.g. mailserver)
is like jumping from skyscraper without a parachute.

Such misfeature should not have a place in upstream.
We should not repeat the same mistake as with allowing authentication without
tls. Ideal would be have this PR just as a downstream patch to make
one particular customer (with unreasonable request due to workarounds on top
of workarounds) happy.
