[Samba] Fwd: Extended acls with AD - problem with default/herited permissions

[Edouard Guigné]

Hello Dale,

I set map acl inherit = yes in global parameters of smb.conf
and set inherit owner = yes locally to my share "groups" of smb.conf

I have followed the wiki 
https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs
It is indicated :
"To configure shares using extended access control lists (ACL), you must 
enable the support in the |smb.conf| file. To enable extended ACL 
support globally, add the following settings to the |[global]| section 
of your |smb.conf| file:

vfs objects = acl_xattr map acl inherit = yes store dos attributes = yes"

Do you mean I should try to add :
inherit acls = yes locally to my share "groups" ?

Should I remove map acl inherit = yes from global parameters of smb.conf ?
