macOS 10.13.6 and SMB shares through DFS

[rraison-prest]

Hello,

We have some problems with macOS Sierra 10.12.6 and SMB shares through DFS.
On our shares we use SMB 3 protocol.
A lot of users (but not all) reported us some random permission issues so we had to force SMB1 protocol via nmsb.conf.

Do you always have this issue with macOS 10.13.6 ?
Do you still need to force SMB1 protocol via nsmb.conf or has it been solved by Apple ?

Thanks in advance.
Best regards,

Hi there,

At my place we always always had issues with SMB shares, but after some tinkering these are the best settings that have work for us:

default
notify_off=yes
signing_required=no
streams=yes
file_ids_off=yes

I would also change the packetsign setting in the OS active directory settings using the following line:

/usr/sbin/dsconfigad -packetsign disable

Hello ovortiz,

Thanks for the information.
What kind of issue do you still have on 10.13.6 ? Performance or permissions ?
We have both with 10.12.6 and that nsmb.conf work for us on Sierra:

[default]
protocol_vers_map=1
streams=yes
file_ids_off=yes
signing_required=no

but it force SMB1 protocol :(

Regards,
