    Samba Server Problems


    Running a fresh install on CentOS 5.5.

    Trying to get Samba server setup to authenticate users from a Windows Active Directory that I have setup.

    I've succeeded in configuring WinBind so that I can log into the CentOS machine using Windows Active Directory Users, however, whenever I try and browse or map to a Samba file share, I just get an error message:

    unknown user name or bad password

    Tried connecting from multiple Windows machines, both from domain members and non-domain members.

    Help please.

    Also: In addition to being able to log into the server -- via SSH and at the console -- using Active Directory user names and passwords, I can also successfully kinit Active Directory users.

    The issue is most probably with your smb.conf file. Successful working of Login and kinit is not confirming about the format of smb.conf;

    Pls post your smb.conf, then i will try to rectify ur prob

    Code:
    # 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 (perhaps too # many!) most of which are not shown in this example # # For a step to step guide on installing, configuring and using samba, # read the Samba-HOWTO-Collection. This may be obtained from:
    #  
    #
    # Many working examples of smb.conf files can be found in the # Samba-Guide which is generated daily and can be downloaded from:
    #  
    #
    # Any line which starts with a ; (semi-colon) or a # (hash) # is a comment and is ignored. In this example we will use a # # for commentry and a ; for parts of the config file that you # may wish to enable # # NOTE: Whenever you modify this file you should run the command "testparm"
    # to check that you have not made any basic syntactic errors.
    #
    #---------------
    # SELINUX NOTES:
    #
    # If you want to use the useradd/groupadd family of binaries please run:
    # setsebool -P samba_domain_controller on # # If you want to share home directories via samba please run:
    # setsebool -P samba_enable_home_dirs on # # If you create a new directory you want to share you should mark it as # "samba-share_t" so that selinux will let you write into it.
    # Make sure not to do that on system directories as they may already have # been marked with othe SELinux labels.
    #
    # Use ls -ldZ /path to see which context a directory has # # Set labels only on directories you created!
    # To set a label use the following: chcon -t samba_share_t /path # # If you need to share a system created directory you can use one of the # following (read-only/read-write):
    # setsebool -P samba_export_all_ro on
    # or
    # setsebool -P samba_export_all_rw on
    #
    # If you want to run scripts (preexec/root prexec/print command/...) please # put them into the /var/lib/samba/scripts directory so that smbd will be # allowed to run them.
    # Make sure you COPY them and not MOVE them so that the right SELinux context # is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts #

    a quick look @ ur smb.conf feel like u had missed some values in it...

    pls have a look at this example

    howtoforge dot com/samba_active_directory

    pls change the above "dot" with the actual dot

    all the best

    I tried redoing smb.conf as per the instructions you linked, but it caused smb to not only not start working, but also caused winbind to stop working, and the smb service wouldn't even start...

    Here's what my smb.conf looked like (I went back to the old one, which, while non-functional, still allowed Samba to work...):

    Code:
    [global]
    	netbios name = LEAHYDC
    	socket options = TCP_NODELAY SO_RCVBUF=16384 SO_SNDBUF=16384
    	idmap uid = 10000-20000
    	winbind enum users = yes
    	winbind gid = 10000-20000
    	workgroup = LEAHY
    	os level = 20
    	winbind enum groups = yes
    	socket address = 192.168.1.1
    	password server = *
    	preferred master = no
    	winbind separator = +
    	max log size = 50
    	log file = /var/log/samba3/log.%m
    	encrypt passwords = yes
    	dns proxy = no
    	realm = LEAHY.LOCAL
    	security = ADS
    	wins server = 
    	wins proxy = no
    [fsroot]
    	comment = Root of the filesystem
    	path = /
    	browseable = yes
    	read only = no
    	inherit acls = yes
    	inherit permissions = yes
    	create mask = 700
    	directory mask = 700
    	valid users = @"DOMAIN+Domain Users"
    	admin users = @"DOMAIN+Domain Admins"
