Hai, Verify dig -x $(hostname -i) Then dig A $(hostname -f) As long as these match any CNAME should work.

Anyway to make a test I configured a new CNAME #?dig server.wdc.mydomain.it ;; ANSWER SECTION: server.wdc.mydomain.it. 900 IN CNAME fileserver.wdc.mydomain.it. fileserver.wdc.mydomain.it. 900 IN A 10.0.0.3 So the CNAME works. I also configured spn: # samba-tool spn list fileserver$ [...] host/server.wdc.mydomain.it host/SERVER [...] But when I try accessing the shares with \\SERVER\whatever [2020/05/21 17:09:10.440340, 3] ../../source3/smbd/smb2_server.c:3274(smbd_smb2_request_error_ex) smbd_smb2_request_error_ex: smbd_smb2_request_error_ex: idx[1] status[NT_STATUS_INVALID_PARAMETER] || at ../../source3/smbd/smb2_ioctl.c:312 -- Lorenzo Milesi - lorenzo.milesi at yetopen.it YetOpen S.r.l. - https://www.yetopen.it/ Via Salerno 18 - 23900 Lecco - ITALY - Tel +39 0341 220 205 - Fax +39 178 6070 222 Think green - Non stampare questa e-mail se non necessario / Don't print this email unless necessary -------- D.Lgs. 196/2003 e GDPR 679/2016 -------- Tutte le informazioni contenute in questo messaggio sono riservate ed a uso esclusivo del destinatario.

'netbios' relies on SMBv1 and hostnames rely on DNS, AD requires DNS, so if you want your computer to have more than one name, you must use a CNAME. The next problem has come over the horizon, SMBv1 is going away, recent versions of Windows and Samba have it turned off by default and you need it for browsing. You had better get used to another way of doing things, there is ongoing work to remove SMBv1 entirely from Samba. Rowland
