browsing home directories with samba
 
I had my samba server configured to let the windows users browse their home directories. I had to reinstall the server, but my old conf didnt worked, and I have just managed to implement login against /etc/passwd and browsing a public directoy, but home directories are inaccesible. Is there any way to solve this or do I have to install some older samba version?

Could you post your smb.conf file. Also, look in the documentation that is installed with samba under /usr/share/doc/samba-<version>/. There is a default smb.conf file that you can use for a reference. It uses "security = user" and has a [homes] service. That sounds a lot like your setup.

Also run "testparm" to check your smb.conf for errors.

# Domain groups:
# Domain groups are now configured by using the 'net groupmap' tool

; idmap gid = 10000-20000
 
# LDAP configuration for Domain Controlling:

# ldap suffix appears first, it is appended to the specific suffix.
# Example for a unix-ish directory layout:
; ldap machine suffix = ou=Hosts
; ldap user suffix = ou=People
; ldap group suffix = ou=Group
; ldap idmap suffix = ou=Idmap
# Example for AD-ish layout:
; ldap machine suffix = cn=Computers
; ldap user suffix = cn=Users
; ldap group suffix = cn=Groups
; ldap idmap suffix = cn=Idmap


# 7. Name Resolution Options:
# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.
; name resolve order = wins host lmhosts bcast

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server
;  wins support = yes

# 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

# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf 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.
;  wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.
  dns proxy = no

# 8. File Naming Options:
# Case Preservation can be handy - system default is _no_
# NOTE: These can be set on a per share basis
;  preserve case = no
;  short preserve case = no
# Default case is normally upper case for all DOS files
;  default case = lower
# Be very careful with case sensitivity - it can break things!
;  case sensitive = no

# Enabling internationalization:
# you can match a Windows code page with a UNIX character set.
# Windows: 437 (US), 737 (GREEK), 850 (Latin1 - Western European),
# 852 (Czech), 861 (???), 932 (Japanese),
# 936 (Simplified Chin.), 949 (Korean Hangul),
# 950 (Trad. Chin.).
# More detail about code page is in
# "http://www.microsoft.com/globaldev/reference/oslocversion.mspx"
# UNIX: ISO8859-1 (Western European), ISO8859-2 (Eastern Eu.),
# ISO8859-5 (Russian Cyrillic), KOI8-R (Alt-Russ. Cyril.)
# This is an example for french users:
;  dos charset = 850
;  unix charset = ISO8859-1


#============================ Share Definitions ==============================
[homes]
  comment = Home Directories
  browseable = yes
  writable = yes
# You can enable VFS recycle bin on a per share basis:
# Uncomment the next 2 lines (make sure you create a
# .recycle folder in the base of the share and ensure
# all users will have write access to it. See
# examples/VFS/recycle/REAME in the samba docs for details
;  vfs object = /usr/lib/samba/vfs/recycle.so



# NOTE: If you have a CUPS print system there is no need to
# specifically define each individual printer.
# You must configure the samba printers with the appropriate Windows
# drivers on your Windows clients. On the Samba server no filtering is
# done. If you wish that the server provides the driver and the clients
# send PostScript ("Generic PostScript Printer" under Windows), you have
# to swap the 'print command' line below with the commented one.
[printers]
  comment = All Printers
  path = /var/spool/samba
  browseable = no
# set to yes to allow user 'guest account' to print.
  guest ok = no
  writable = no
  printable = yes

# This share is used for Windows NT-style point-and-print support.
# To be able to install drivers, you need to be either root, or listed
# in the printer admin parameter above. Note that you also need write access
# to the directory and share definition to be able to upload the drivers.
# For more information on this, please see the Printing Support Section of
# /usr/share/doc/samba-<version>/Samba-HOWTO-Collection.pdf
[print$]
  path = /var/lib/samba/printers
  browseable = yes
  read only = yes
  write list = @adm root
  guest ok = yes
[public]
  comment = Public Stuff
  path = /home/public
  public = yes
  writable = yes
  printable = no

testparm reports no problems. Currently, users can browse and see the public folder, but they just see a homes folder which is inaccessible, insted of seeing their home folder as before. I thought to downgrade samba, but seems that versions previous to 3.0.33 have been removed from portage.

This is the [homes] service that SuSE uses:
Code:

[homes]
        comment = Home Directories
        valid users = %S, %D%w%S
        browseable = No
        read only = No
        inherit acls = Yes

However the Samba default is very similar to yours:
Code:

[homes]
  comment = Home Directories
  browseable = no
  writable = yes

From the smb.conf manpage:
Code:

      If you decide to use a path = line in your [homes] section, it may be useful to use the %S macro. For example:

          path = /data/pchome/%S

      is useful if you have different home directories for your PCs than for UNIX access.

Code:

      The browseable flag for auto home directories will be inherited from the global browseable flag, not the [homes] browseable
      flag. This is useful as it means setting browseable = no in the [homes] section will hide the [homes] share but make any auto
      home directories visible.

If you have "browseable = no", there will be the users home directory name in the browse list, but not "homes". If you use "browseable = yes" you will see both. I had used a [profile] service on my desktop. I commented it out and used your [home] service instead. It works for me.

Here is another difference from what I have:
# TDB backend
passdb backend = tdbsam

Look at "sudo pdbedit -L". Are all the users listed? Perhaps when you re-installed you didn't backup the samdba trivial database files.

From the Samba HOWTO, these files should be backed up.
Code:

account_policy.tdb        Y       
group_mapping.tdb        Y       
lang_en.tdb        Y       
netsamlogon_cache.tdb        Y       
ntdrivers.tdb        Y       
ntforms.tdb        Y       
ntprinters.tdb        Y       
printing directory        Y       
registry.tdb        Y       
share_info.tdb        Y       
winbindd_idmap.tdb        Y       
wins.tdb        Y       
secrets.tdb        Y       
This tdb file stores internal settings such as the machine and the domain SID, secret passwords that are used with LDAP, the machine secret token, etc. This is an essential file that is stored in a secure area. Vendors locate this in various folders. Check smbd -b to find its location on your system.
schannel_store.tdb        Y       

This stores secure channel access token information used with SMB signing.
passdb.tdb        Y       

This stores the Samba SAM account information when using a tdbsam password backend.

Some may not be used in your configuration. You may want to install the samba docs, and read "Chapter 41. Managing TDB Files".
I think you may need to run smbpasswd to add the users back in the password backend.

Good Luck!

Setting browseable to no makes dissapear the home directory, but no user folder is displayed. I made a backup of my /etc/samba folder, so, if the tdb files are somewhere else I lost them.

jschiwal 08-08-2009 11:37 AM

Those files are in /var/lib/samba/.
