Hi there. I am using Samba 4.2.10 on Scientific Linux 7.1.
I am currently trying to make an SMB share that is accessible to all of our
Active Directory domain users. Additionally, this share needs to allow
read/write access for our clients, who are using FTP. All of the subdirectories
for this share represent an individual FTP user's folder.
The share is named "ftpshares". The problem that I am currently
having with this share is that I cannot seem to get the "force create
mode" setting to perform as expected. I would like it to force 0766 to the
share, its subdirectories, and the files created within. However, when I look
at a file that was created from a windows machine, these are the permissions
that I see:
-rwxrwx-w-+ 1 root domain users 0 Jun 21 12:26 test.txt
This is a problem, as FTP users can only write to the file. This seems like a
really strange behavior. I have posted my smb.conf for your review. Any help
you can give me would be greatly appreciated.
# This is the main Samba configuration file. For detailed information about the
# options listed here, refer to the smb.conf(5) manual page. Samba has a huge
# number of configurable options, most of which are not shown in this example.
#
# The Official Samba 3.2.x HOWTO and Reference Guide contains step-by-step
# guides for installing, configuring, and using Samba:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# The Samba-3 by Example guide has working examples for smb.conf. This guide is
# generated daily: http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# In this file, lines starting with a semicolon (;) or a hash (#) are
# comments and are ignored. This file uses hashes to denote commentary and
# semicolons for parts of the file you may wish to configure.
#
# Note: Run the "testparm" command after modifying this file to check
for basic
# syntax errors.
#
#---------------
# Security-Enhanced Linux (SELinux) Notes:
#
# Turn the samba_domain_controller Boolean on to allow Samba to use the useradd
# and groupadd family of binaries. Run the following command as the root user to
# turn this Boolean on:
# setsebool -P samba_domain_controller on
#
# Turn the samba_enable_home_dirs Boolean on if you want to share home
# directories via Samba. Run the following command as the root user to turn this
# Boolean on:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory, such as a new top-level directory, label it
# with samba_share_t so that SELinux allows Samba to read and write to it. Do
# not label system directories, such as /etc/ and /home/, with samba_share_t, as
# such directories should already have an SELinux label.
#
# Run the "ls -ldZ /path/to/directory" command to view the current
SELinux
# label for a given directory.
#
# Set SELinux labels only on files and directories you have created. Use the
# chcon command to temporarily change a label:
# chcon -t samba_share_t /path/to/directory
#
# Changes made via chcon are lost when the file system is relabeled or commands
# such as restorecon are run.
#
# Use the samba_export_all_ro or samba_export_all_rw Boolean to share system
# directories. To share such directories and only allow read-only permissions:
# setsebool -P samba_export_all_ro on
# To share such directories and allow read and write permissions:
# setsebool -P samba_export_all_rw on
#
# To run scripts (preexec/root prexec/print command/...), copy them to the
# /var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them.
# Note that if you move the scripts to /var/lib/samba/scripts/, they retain
# their existing SELinux labels, which may be labels that SELinux does not allow
# smbd to run. Copying the scripts will result in the correct SELinux labels.
# Run the "restorecon -R -v /var/lib/samba/scripts" command as the
root user to
# apply the correct SELinux labels to these files.

# option if you already have a Windows NT domain controller performing this
task.

# ----------------------- Browser Control Options ----------------------------
#
# local master = when set to no, Samba does not become the master browser on
# your network. When set to yes, normal election rules apply.
#
# os level = determines the precedence the server has in master browser
# elections. The default value should be reasonable.

# server.
#
# wins server = tells the NMBD component of Samba to be a WINS client.

# of a non WINS capable client. For this to work, there must be at least one
# WINS server on the network. The default is no.

#
# The options in this section allow you to configure a non-default printing
# system.
#
# load printers = when set you yes, the list of printers is automatically
# loaded, rather than setting them up individually.
#
# cups options = allows you to pass options to the CUPS library. Setting this
# option to raw, for example, allows you to use drivers on your Windows clients.
#
# printcap name = used to specify an alternative printcap file.
#
; printcap name = /etc/printcap
# obtain a list of printers automatically on UNIX System V
systems:

; printing = cups
# --------------------------- File System Options ---------------------------
#
# The options in this section can be un-commented if the file system supports
# extended attributes, and those attributes are enabled (usually via the
# "user_xattr" mount option). These options allow the administrator to
specify
# that DOS attributes are stored in extended attributes and also make sure that
# Samba does not change the permission bits.
#
# Note: These options can be used on a per-share basis. Setting them globally
# (in the [global] section) makes them the default for all shares.

See here for more info: https://wiki.samba.org/index.php/Shares_with_Windows_ACLs Having said that, there are a couple of things in your smb.conf that I think you need to look at. Do you really understand what you have set in 'socket options' ? are you sure you need this line ? Second thing is a definite problem, you have: idmap config * : range = 100000-199999 and: idmap config RSC : range = 100000-199999 These ranges are not supposed to overlap, never mind overlap, both your ranges are exactly the same, you need to change one.

Rowland, Thanks for your input. Per your suggestions, I have changed the global options in my configuration: [global] netbios name = FS04 workgroup = RSC server string = Samba Server Version %v security = ads realm = AD.RINGSIDECREATIVE.COM use sendfile = true idmap config * : backend = tdb idmap config * : range = 200000-299999 idmap config RSC : backend = rid idmap config RSC : range = 100000-199999 winbind separator = + winbind enum users = yes winbind enum groups = yes winbind use default domain = yes winbind refresh tickets = yes restrict anonymous = 2 log file = /var/log/samba/log.%m max log size = 50 I then reloaded the samba service (systemctl restart smb) However, I still get the same problems when creating a file from a windows machine. I appreciate the suggestion about using Windows ACLs. However, I think that doing so would also require a reengineering of the FTP side of this server. I'd like for the server to function without the use of Windows ACLs, if possible. Are there any logs that I can provide that will assist with troubleshooting this issue? I have looked through the logs in /var/log/samba, but I haven't found very much useful information. Let me know. Thanks. -----Original Message----- From: samba [mailto:samba-bounces at lists.samba.org] On Behalf Of Rowland penny Sent: Tuesday, June 21, 2016 1:23 PM To: samba at lists.samba.org Subject: Re: [Samba] Force Create Mode Problems On 21/06/16 17:31, Eric Krause wrote:> Hi there.

The problem that I am currently having with this share is that I cannot seem to get the "force create mode" setting to perform as expected. I would like it to force 0766 to the share, its subdirectories, and the files created within. However, when I look at a file that was created from a windows machine, these are the permissions that I see: > > -rwxrwx-w-+ 1 root domain users 0 Jun 21 12:26 test.txt > > This is a problem, as FTP users can only write to the file. This seems like a really strange behavior. I have posted my smb.conf for your review. Any help you can give me would be greatly appreciated. > > # This is the main Samba configuration file.

See here for more info: https://wiki.samba.org/index.php/Shares_with_Windows_ACLs Having said that, there are a couple of things in your smb.conf that I think you need to look at. Do you really understand what you have set in 'socket options' ? are you sure you need this line ? Second thing is a definite problem, you have: idmap config * : range = 100000-199999 and: idmap config RSC : range = 100000-199999 These ranges are not supposed to overlap, never mind overlap, both your ranges are exactly the same, you need to change one.
