Hello, I'm trying to replace an old Windows Server 2003 with Samba 4 and I've got a problem trying to add some DNS entries. When I open the RSAT DNS manager I got an Access Denied error and I can't edit the zones. My config file is the generated by samba-tool and I'm using Samba 4.7.0rc5 compiled on a Debian 8 amd64: [global] netbios name = DC1 realm = DOMAIN.DOM workgroup = DOMAIN server role = active directory domain controller idmap_ldb:use rfc2307 = yes dns forwarder = 8.8.8.8 [netlogon] path = /server/samba/bin/var/locks/sysvol/domain.dom/scripts read only = No [sysvol] path = /server/samba/bin/var/locks/sysvol read only = No All seems to be working fine, because I'm able to join the domain, login on that computer and manage other things like Users and Groups, Policies... but DNS just drops me an Acces Denied message. The log shows this: [2017/09/12 11:17:01.416939, 2] ../source4/rpc_server/dcerpc_server.c:1804(dcesrv_request) dcesrv_request: restrict auth_level_connect access to [dnsserver] with auth[type=0xa,level=0x2] on [ncacn_ip_tcp] from [ipv4:192.168.0.52:65013] [2017/09/12 11:17:01.444307, 2] ../source4/rpc_server/dcerpc_server.c:1804(dcesrv_request) dcesrv_request: restrict auth_level_connect access to [dnsserver] with auth[type=0xa,level=0x2] on [ncacn_ip_tcp] from [ipv4:192.168.0.52:65015] [2017/09/12 11:17:01.469071, 2] ../source4/rpc_server/dcerpc_server.c:1804(dcesrv_request) dcesrv_request: restrict auth_level_connect access to [dnsserver] with auth[type=0xa,level=0x2] on [ncacn_ip_tcp] from [ipv4:192.168.0.52:65017] [2017/09/12 11:17:01.494096, 2] ../source4/rpc_server/dcerpc_server.c:1804(dcesrv_request) dcesrv_request: restrict auth_level_connect access to [dnsserver] with auth[type=0xa,level=0x2] on [ncacn_ip_tcp] from [ipv4:192.168.0.52:65019] Is there any way to fix this?, Maybe I forgot something like add the computer to a group for example... I'm using the Administrator user, so it should have access to all. Thanks, and greetings!! -- _________________________________________ Daniel Carrasco Marín Ingeniería para la Innovación i2TIC, S.L.

You can use samba-tool or set allow dcerpc auth level connect = yes I hope this helps, Andrew Bartlett -- Andrew Bartlett http://samba.org/~abartlet/ Authentication Developer, Samba Team http://samba.org Samba Developer, Catalyst IT http://catalyst.net.nz/services/samba
