[Samba] GPO Editor says "Access denied" for Group Policy Objects

[Luis Peromarta]

I don’t think you need winbind on a DC as user mapping is done by its own databases. I think you have mixed up member server configs into DC configs.

A smb.conf like this should be enough:

[global]
	dns forwarder = 1.1.1.1
	netbios name = AAA
	realm = XXXT
	server role = active directory domain controller
	workgroup = MAD
	idmap_ldb:use rfc2307  = yes

#Allow this for free radius to work
	ntlm auth = mschapv2-and-ntlmv2-only

# Disable Netbios
        disable netbios = yes

[sysvol]
	path = /var/lib/samba/sysvol
	read only = No

[netlogon]
	path = /var/lib/samba/sysvol/XXXTscripts
	read only = No


See this for details.
