小規模オフィスサーバーとUIDの翻訳

私は、ユーザーが自分のファイルを保存し、グループがファイルを共有できる別のディレクトリを持つことができるように、オフィスに小さなサーバーを設定したいと思います。また、インターネット経由でインストールしたいユーザーとクライアントもあります。また、個々のディレクトリへのアクセスと権限を指定できるようにしたいです。一部は Windoze を使用している可能性があります。

最初はCIFSを使用してLANを設定しようとしました。サーバーには、自分自身とゲストで作成された他のユーザーのために設定されたアカウントがあります。 sysconfig-sambaをインストールしました。次に、資格情報に使用されるユーザーとパスワードを追加できるSambaサーバー構成ツールを使用して共有を構成しました。 /etc/samba/smb.conf は次のようになります:

# 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 =======================

[global]

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field
    server string = %h server (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
#   wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
    dns proxy = no

#### 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
    log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
    max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
    syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
    panic action = /usr/share/samba/panic-action %d


####### 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 sever" 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.
    server role = standalone server

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.  
;   passdb backend = tdbsam

    obey pam restrictions = yes

# 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.
    unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<[email protected]> for
# sending the correct chat script for the passwd program in Debian Sarge).
    passwd program = /usr/bin/passwd %u
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# 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'.
    pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
    map to guest = bad user

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

#
# The following settings only takes effect if 'server role = primary
# classic domain controller', 'server role = 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.  
; add group script = /usr/sbin/addgroup --force-badname %g

############ Misc ############

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting

# for something else.)

システムに追加のユーザーを追加したかったのですが、ほとんどのユーザーがローカル コンピューターで 1000 または 1000 に近い UID を持っていたため、問題が急速に発生しました。ローカルコンピュータのUIDをサーバーのUIDに変更しようとすると、まだ機能しません。共有ディレクトリのファイルには、クライアントが設定した所有権と権限があり、他の人がアクセスできないためです。

UIDとGIDはサーバーに設定されていますが、自分のコンピュータにインストールしたときにユーザーに正しく表示されるように（たとえば1000に変換するなど）、サーバーを設定する簡単な方法はありますか？私がすべきことは、個々のディレクトリへのアクセスと権限を制御できるようにサーバーで認証を完了することだけです。 UbuntuのドキュメントでOpenLDAPを見ようとしましたが、5分後に頭が飛び出したようです。

これを行う簡単な方法が必要です。私は現在Mintを使用していますが、少なくともサーバーでは主流のUbuntuバージョンに移動できます。あまり複雑ではない限り、コマンドラインとテキストファイルを使用してうれしいです。もしそうなら、私はOpenLDAPを使い続けたいと思います。
