Re: [Samba] member server idmap config (auto)rid




Ok debian stretch.. 

Go here. 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=862580#39
Review all steps there. ( message 39, Date: Mon, 22 May 2017 10:21:18 +0200 ) 

And if you change something, mark it so you can find it back, but that config works. 
If it fails, post you smb.conf and post where you see errors based on the steps of above link. 

Without smb.conf is a guessing game.
