Hi,
In our Samba 4.13.17 configuration file, we have defined the user home path as
below:
path = /home/%U/FILES
It worked find up to Ubuntu 20.04 with package version Samba version
2:4.13.17~dfsg-0ubuntu1.20.04.2
But since update to Samba version 2:4.13.17~dfsg-0ubuntu1.20.04.4, it
does no longer works with error message: canonicalize_connect_path
failed, preventing end-user accessing their home drive.

../../source3/smbd/service.c:785(make_connection_snum)
Jan 25 11:17:52 ff0119 smbd[2657856]: make_connection_snum:
canonicalize_connect_path failed for service john, path /home/FILES
Indeed in the logs, instead of trying to access /home/john/FILES for
user john, Samba seems to be trying to access /home/FILES (the user part
of the path being stripped out for some unknown reason). It is like the
%U value become empty or unreadable.
Other paths such as logon script do not seem affected by the issue. The
other shared folders remain fully accessible to end-user but not their
home directory.
For now the only workaround we may have found working is either:
- to use a different home path without sub-folder: /home/%U in the samba
configuration
- downgrade Samba to package version 2:4.13.17~dfsg-0ubuntu1.20.04.2
- setup manually a new share with the full manual path of the user home
directory (/home/john/FILES) without using the %U then access to the directory
works... not the most convenient in a large multi-user environment..
In help you could provide in resolving this issue quickly would be much
appreciated.
Regards,
Richard
