Public bug reported:

Hi, since upgrading to Ubuntu 20.04 I cannot gio mount or otherwise
connect to my companies' samba shares due to them requiring the NT1
protocol. Adding client min protocol = NT1 to ~/.smb/smb.conf works, but
I need to deploy this to a largish number of managed machines. The file
/etc/samba/smb.conf on these machines looks like this:

include = /usr/share/samba/smb.conf
include = /usr/share/tait-config/ttde-smb.conf
include = /etc/samba/user.conf

where /usr/share/samba/smb.conf is the config template shipped with
samba itself, /usr/share/tait-config/ttde-smb.conf contains config
overrides that are deployed via a locally built and hosted config
package (the file itself is not a dpkg config file so will get silently
rewritten when we update the package) and finally, individual machines'
users can customise the config in /etc/samba/user.conf.

Unfortunately adding client min protocol = NT1 only works in the first
included file but not the second where we really need this to go. It
seems that there is a bug in the included config file parser somewhere.

ubuntu-bug requested me to include this information though I'm not sure
how relevant it is:
