Description Andrew Bartlett 2018-05-10 18:55:32 UTC
This AD DC's domain is very close, in AD DC configurations over a internal ncacn_np pipe and otherwise in the same process via C linking.  It is however very expensive to re-create the binding handle per SID->name lookup, so keep a cache.

This makes samba-tool netacl sysvolreset and the nss tests much faster.
