Hai Marty, sorry for the late relpy, had a few days off.
I upgraded kopano and samba.
I’m suspecting a problem with php-smbclient, and that might/is most probely related to samba 4.11.
i’ll see if i can make the time for it this week to have a better look, so i can provide a bit more info.
My running setup is atm :
Debian Buster
Kopano 9.0.1 ( dev packages )
samba 4.11.3 (packages from own apt repo)
I’ll update the setup this week and report back again.
As I provide the debian samba packages for the samba list also and i just released my latest samba 4.11.3 packages.
