Samba permission issues

At least some of the structure looks as if it’s got mixed up, items from share definitions are mixed with items from or for other sections.

Have you run the Samba’s associated parameter checking utility testparm on your configuration file while attempting connections to the shares through it?

Thanks again. When I ran testparm (which sounds to me like a fun job taste-testing Parmesan cheese), I got this:

Load smb config files from /etc/samba/smb.conf
lpcfg_do_global_parameter: WARNING: The "encrypt passwords" option is deprecated
Unknown parameter encountered: "server smb encrypt"
Ignoring unknown parameter "server smb encrypt"
Unknown parameter encountered: "client smb encrypt"
Ignoring unknown parameter "client smb encrypt"
Loaded services file OK.
Weak crypto is allowed
Server role: ROLE_STANDALONE

But, based on the documentation you sent, what I have in my config looks right. (The documentation did say default instead of required, but neither one seems to work.)

server min protocol = SMB3_11 
    server smb encrypt = required 
    server signing = required 
    client min protocol = SMB3_11 
    client smb encrypt = required 
    client signing = required

So, any more thoughts?

When I looked at the config file there seemed to be entries that could have been used when defining a Samba share for the media share. But they were in the global section, these can potentially be not helping with your inaccessible Samba share. You may need to restore a backup of the samba config file, then re-add the samba SMB 3.11 entry, client server signing and/or client server encryption.

Afterwards using the GUI only then re-create the share definition along with configuring the other shares.

Argh, this is still not working.

Here’s the config file now after following your instructions about rebuilding the share.

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which 
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic 
# errors. 

#======================= Global Settings =======================

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects

# Cap the size of the individual log files (in KiB).

# We want Samba to only log to /var/log/samba/log.{smbd,nmbd}.
# Append syslog@1 if you want important messages to be sent to syslog too.

# Do something sensible when Samba crashes: mail the admin a backtrace


####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller". 
#
# Most people will want "standalone server" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.


# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

########## Domains ###########

#
# The following settings only takes effect if 'server role = classic
# primary domain controller', 'server role = classic backup domain controller'
# or 'domain logons' is set 
#

# It specifies the location of the user's
# profile directory from the client point of view) The following
# required a [profiles] share to be setup on the samba server (see
# below)
;   logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
#   logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
;   logon drive = H:
#   logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
;   logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe.  The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the 
# SAMR RPC pipe.  
# The following assumes a "machines" group exists on the system
; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.

I thought someone recommended something like this but I don’t see the post now?

Before I ever installed Debian and Webmin on this box, I tried to install OMV. I got critical errors on installation.

What were the errors? I don’t remember. It has been three years. I was just desperate for any OS that would work AT ALL.

I got OMV to work on my Raspberry Pi 3B+ before that, but the hardware limitations of the Pi made it unreliable.

Maybe there was some hardware compatibility issue with my Buffalo TeraStation that prevented it from installing?
