Hi All, I am running into an issue mounting a Samba share from our Linux server. We are running Samba 4.8.8 on CentOS 7.6.1810. I have done a some testing, and I can't get the root cause of the error. Testing: CentOS 7.6 client -> Samba server, mounting fails - mount.cfs mount error(13): Permission denied CentOS 7.6 client -> Win10 desktop share, mounting works Fedora 29 client -> Samba server, mounting fails - mount.cfs mount error(13): Permission denied Fedora 29 client -> Win10 desktop share, mounting works Window 10 client -> Samba server, mounting works So there is a problem between the server and Linux clients. Originally I was thinking it was linked to this closed bug report, https://bugzilla.samba.org/show_bug.cgi?id=8950. The error is same, but the path leading to the share is readable, so it isn't the same thing. I am using the following command to mount the share. # mount -t cifs //xxxxxxxxxxxxxxxxxxxx/paulg /tmp/1 -o user=paulg,uid=2381,gid=1000,sec=ntlmsspi Password for paulg@//xxxxx/paulg: ********* mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I tried the following security options. sec=ntlmsspi sec=ntlmssp sec=ntlmv2 sec=ntlmv2i With the same results. I wonder why Linux clients having issues? Any pointers?

If so, then I suggest asking on the sssd-users mailing list, Samba isn't doing the authentication. If you aren't using sssd, then the Unix domain members smb.conf is missing all the 'idmap config' lines, see here: https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member Rowland

Of you gave to little info or you missed this part below. ;-) First, did you define the cifs SPN/UPN? Setup for a member : kinit Administrator net ads keytab add cifs/srv-a1.your.dnsdomain.tld -k ( optional : net ads keytab add root/srv-a1.your.dnsdomain.tld -k ) And make sure the cifs/spn is also listed in the AD. I set this manualy through ADUC. And i would try with just : mount -t cifs //xxxxxxxxxxxxxxxxxxxx/paulg /tmp/1 -o sec=ntlmsspi Greetz, Louis> -----Oorspronkelijk bericht----- > Van: samba [mailto:samba-bounces at lists.samba.org] Namens Paul > Griffith via samba > Verzonden: maandag 22 april 2019 20:01 > Aan: samba at lists.samba.org > Onderwerp: Re: [Samba] mount.cfs mount error(13): Permission denied > > On 4/22/19 10:18 AM, Rowland Penny via samba wrote: > > On Mon, 22 Apr 2019 09:48:31 -0400 > > Paul Griffith via samba <samba at lists.samba.org> wrote: > > > >> Hi All, > >> > >> I am running into an issue mounting a Samba share > from our Linux > >> server.

Possibly Parallel Threads
- mount.cfs mount error(13): Permission denied
- NT_STATUS_ACCESS_DENIED on a directory I have permission to access
- NT_STATUS_ACCESS_DENIED on a directory I have permission to access
- Copying (Samba -> WinXP SP2) MATLAB generated .jpg files very slow.
