Hi, I'm running an old Sonos Play5 speaker which has access to my music library hosted on Raspberry Pi. My problem is that Samba 4.9.5 which is installed on a Raspi3 works without problems. But Samba 4.17.12 on Raspi4 does not work. The error is "Zugriff auf //raspi4/mp3 wurde verweigert" (access to //raspi4/mp3 rejected). I activated server min protocol = NT1 in /etc/samba/smb.conf already because the Sonos Play5 kernel is rather old (2.4.22). But this did not help. Any suggestions? What I have in mind is to install the old Samba version 4.9.5 on Raspi4 too. But maybe there's a better solution. Thanks in advance!
