Cups-Server mit SMB lehnt Verbindungen ab (smb.conf)?

#
# 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]
	log file = /var/log/samba/log.%m
	printing = cups
	unix password sync = yes
	obey pam restrictions = yes
	usershare allow guests = yes
	map to guest = bad user

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field

#### 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 = 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

# RPC pipe.
