Hi Michael,
thanks for getting back to me question.
Yes, I am trying to add a SMB/CIFS share in the nextcloud management UI to all my users and not succeeding.
The share host can be pinged from within the nextcloud docker shell and the share accessed with smbclient
When I try to mount it in the nextcloud UI, I get a red exclamation point. There is no record in the SAMBA logs of any attempt made from the nextcloud docker network or the docker host network. Obviously, when I use the smbclient, I get the logs on the SAMBA server and all is OK. I tried editing the smb.conf to specify the domain in the nextcloud to no avail. The SAMBA server is a member of the domain and accessible from other clients and or from Kopano, running on the same docker host.
