Summary of the issue you are facing:
Hello,
I have been using Nextcloud AIO with an SMB mount to my external Samba server for a very long time. Until now, this Samba server was a member of an Active Directory.
However, after completely switching to Linux and using FreeIPA, the mount no longer works.
All my other systems can mount the filesystem as before, but it doesn’t work with Nextcloud.
It even works if I try the mount directly from the Docker container (nextcloud-aio-nextcloud) using smbclient.
However, in the web interface, I fail and get the following messages in Samba’s debug logs:
