    I'm glad that you have it working now. I hope everything else goes smoothly for you!

    Re: Ubuntu Server 7.10: OpenLDAP + SAMBA Domain Controller

    hi

    i will be trying this out tomorrow evening hopefully

    VERY useful guide, especially compared to a lot of the ones i have found!!

    i'm setting it up on a small network elsewhere so i cannot start it ATM.

    i will quite likely be posting back on here for help etc in configuring it and making it work! sorry!!

    i'm very new to linux etc so don't know diddly squat about it! but i'm here to learn and all so hopefully i should get on alright.

    I'm glad that you'll be trying out this guide. I wrote it in such a way that even a complete newbie should be able to apply it as long as you have patience and read all the directions. The majority is all copy and paste. I know this because I'm still quite a newbie when it comes to Linux.

    Good luck!

    Re: Ubuntu Server 7.10: OpenLDAP + SAMBA Domain Controller

    Okay I have followed the guide line by line.

    Below is my smb.conf

    Code:
    #
    # 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
    #
    # 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 commentary 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. 
    #

    Thanks for the help!

    Re: Ubuntu Server 7.10: OpenLDAP + SAMBA Domain Controller

    misilot:

    I believe that the /etc/smbldap-tools/smbldap_bind.conf file may have the incorrect authentication information.

    entry dc=misilo,dc=local already exist.
    adding new entry: ou=Users,dc=misilo,dc=local
    failed to add entry: modifications require authentication
    That tells me that it is trying to add the information but it is failing authentication.

    I would check the smbldap_bind.conf file again.

    Thanks,

    Re: Ubuntu Server 7.10: OpenLDAP + SAMBA Domain Controller

    right i'm giving it a go, but i'm afraid i've run into a few issues already!1

    it is with the assumptions bit (not far i know lol)

    basically, i don't know how to set any of that stuff, didn't realise that a ubuntu server was CLI!! i thought tere was a gui involved

    basically, i don't know hardly any commands. i duno how to enable stuff in repositories, i duno how to set my static ip. etc etc!!

    tell me, is there a way to make it GUI? cos that wud be sooo much easier for me i think

    what you reckon??

    failed to modify entry: modifications require authentication at /usr/sbin/smbldap-passwd line 227, <STDIN> line 2.
    Unable to change password: modifications require authentication at /usr/sbin/smbldap-passwd line 261, <STDIN> line 2.
    And I can't figure out why it isn't working. I rechecked all the config files and all of them look right still.

    Thanks for the help,

    Try changing the password with the smbpasswd program. This is what I had to use to change a password.
