[Samba] [4.13.13-Debian] " reopen_one_log: Unable to open new log file '/var/log/samba/': Is a directory"?

[Gilles]

Hello,

I see this kind of message in /var/log/samba/log.nmbd

[2023/01/11 10:04:49.943723,  0] ../../lib/util/debug.c:1104(reopen_one_log)
reopen_one_log: Unable to open new log file '/var/log/samba/': Is a 
directory

Here's what I have in smb.conf:

smb.conf: log file = /var/log/samba/%m

Or can I fix that error?

Thank you.
