Re: [Samba] Advice on Winbindd and NTLM Auth Performance




Hello Everyone,

Thanks for your inputs I have followed whats here https://wiki.freeradius.
org/guide/Active-Directory-direct-via-winbind . Apart from the different
location for the directories. I have added the recommended options in samba.

However I cannot see why this would make a difference to performance.

The guide for setting up a samba domain member seems more to be aimed at
the whole samba stack I only need winbind is that not correct?

Apologies I'm new to samba.

Many Thanks
Arnab
