Created attachment 18175 [details] level 10 debug logs, tcpdump packet capture, and config files for both cases I have Samba 4.19.2 running on Debian unstable with a smb.conf that looks like this: [global] server role = standalone server map to guest = bad user debug level = 10 debug pid = true max log size = 0 hosts deny = ALL hosts allow = 10.45.12.20 #include = /etc/samba/%I include = /etc/samba/10.45.12.20 The file 10.45.12.20 looks like this: [testshare] path = /dfg read only = No guest ok = Yes Now on my client (running Debian stable version 12.2, with an ip address of 10.45.12.20) I run the following smbclient command (when it asks for a password I just press Enter): jdietrch@saturn:~$ smbclient -L bbccz Password for [WORKGROUP\jdietrch]: Sharename Type Comment --------- ---- ------- testshare Disk IPC$ IPC IPC Service (Samba 4.19.2-Debian) SMB1 disabled -- no workgroup available jdietrch@saturn:~$ Notice that the share named "testshare" appears. This is just what I would expect. However, I then change the smb.conf to this: [global] server role = standalone server map to guest = bad user debug level = 10 debug pid = true max log size = 0 hosts deny = ALL hosts allow = 10.45.12.20 include = /etc/samba/%I #include = /etc/samba/10.45.12.20 The only change is that I am now using variable substitution: %I instead of explicitly specifying the filename. The end result should be the same, since that is the IP address of the client. However, that is not the case. Notice what happens when I run the same smbclient command: jdietrch@saturn:~$ smbclient -L bbccz Password for [WORKGROUP\jdietrch]: Sharename Type Comment --------- ---- ------- IPC$ IPC IPC Service (Samba 4.19.2-Debian) SMB1 disabled -- no workgroup available jdietrch@saturn:~$ In particular, notice that the share named "testshare" does not appear anymore. And I do have access to the share. If I connect to it directly by name, that works just fine: jdietrch@saturn:~/software$ smbclient //bbccz/testshare Password for [WORKGROUP\jdietrch]: Try "help" to get a list of possible commands. smb: \> ls .

For both cases I have recorded level 10 debug logs and a tcpdump packet capture, which I will attach to this bug report. If there is any further information that I can give, or anything else I can do that would be helpful, please don't hesitate to ask.

Samba can also function as an Active Directory or NT4-style domain controller, and can integrate with Active Directory realms or NT4 domains as a member server. . This package provides the components necessary to use Samba as a stand-alone file and print server or as an NT4 domain controller. For use in an NT4 domain or Active Directory realm, you will also need the winbind package. To use samba as an Active Directory domain controller (AD DC), please install samba-ad-dc package. . This package is not required for connecting to existing SMB/CIFS servers (see smbclient) or for mounting remote filesystems (see cifs-utils). Homepage: https://www.samba.org
