| − | Using sudo at a terminal on the client does give some errors but not all those highlighted above, maybe the HowTo was not followed correctly or maybe it does not work with Xubuntu.

| − | Synaptic is no longer installed by default in Ubuntu although I believe it is still used by some distros based on Ubuntu. There has been a bug in Synaptic which prevents it loading from the menu. There is a simple workaround which I have tested and which works, I will add it to the HowTo if it's still considered worthwhile continuing.
| |
| − |
| |
| − | It seems this HowTo throws up several error messages but it does seem to work therefore what is the consensus, do I continue or shall I scrap it due to the error messages? [[User:Relayer|Relayer]] ([[User talk:Relayer|talk]]) 15:01, 22 February 2013 (MST)

| − | ==Ubuntu 12.04 LTS Authentication==
| |
| − |
| |
| − | ===Introduction===
| |
| − | The following details the setup of Ubuntu 12.04 LTS (Precise Pangolin) as a desktop to authenticate users against SME Server 8.0 using Samba and Winbind. It assumes login is via Ubuntu's standard GDM login screen.
| |
| − |
| |
| − | Ubuntu 12.04 is a long term service release, and will be supported on the desktop until April 2017.
| |
| − |
| |
| − | ===Install Ubuntu===
| |
| − | *Download the Ubuntu .iso and install.
| |
| − | {{Tip box| When prompted for a user name to log in with, give a non-SME Server user such as 'localuser', as this first user effectively becomes a local user with sudo root access.
| |
| − |
| |
| − | Make sure you set the 'Name of this Computer' to something less than 15 characters.}}
| |
| − | *Complete install, login and apply all updates.
| |
| − | {{Note box| For VirtualBox VM installation only, install the 'Guest Additions'. Mount the media and run autorun.sh. For VMware, install the VMware Tools. Untar the installer and run vmware-install-tools.pl}}
| |
| − | ===Additional Packages===
| |
| − | Use the 'Software Manager' to install additional packages
| |
| − |
| |
| − | auth-client-config
| |
| − | winbind
| |
| − | libpam-mount
| |
| − | cifs-utils
| |
| − |
| |
| − | Optionally, you can use the command line:
| |
| − |
| |
| − | sudo apt-get install auth-client-config winbind libpam-mount cifs-utils
| |
| − |
| |
| − | ===Samba Modifications===
| |
| − | *Open an 'Applications - Accessories - Terminal' cli and change to root privileges
| |
| − | sudo su
| |
| − | *Open and edit /etc/samba/smb.conf. Find the relevant lines and alter them or uncomment them as below. Some lines may not exist and may need to be added.
| |
| − | :Replace <WORKGROUP> below with the 'Windows workgroup' name of your SME Server. Replace <ip of sme server> below with the internal network ip address of your SME Server.
| |
| − | workgroup = <WORKGROUP>
| |
| − | wins server = <ip of sme server>
| |
| − | name resolve order = wins host lmhosts bcast
| |
| − | security = domain
| |
| − | socket options = TCP_NODELAY
| |
| − | idmap config * : backend = tdb
| |
| − | idmap config * : range = 10001-20000
| |
| − | idmap config DOMAIN : backend = rid
| |
| − | idmap config DOMAIN : range = 10000-20000
| |
| − | idmap config DOMAIN : base_rid = 0
| |
| − | template shell = /bin/bash
| |
| − | template homedir = /home/%D/%U
| |
| − | winbind enum users = yes
| |
| − | winbind enum groups = yes
| |
| − | winbind cache time = 10
| |
| − | winbind use default domain = yes
| |
| − | *To check validation of smb.conf, run
| |
| − | testparm
| |
| − | *If all OK, then run
| |
| − | net rpc join -D <WORKGROUP> -U admin
| |
| − | (I had to use sudo it this or you get /var/lib/secrets.tdb not found)
| |
| − |
| |
| − | :Enter the admin password for the SME Server when prompted and you should get a message,
| |
| − | Joined domain <WORKGROUP>
| |
| − |
| |
| − | *Restart the machine to apply the changes.
| |
| − | * Login as the local user, open a Terminal cli and 'sudo su' again
| |
| − | *The following commands should now list users, groups and available shares respectively from the SME Server
| |
| − | wbinfo -u
| |
| − | wbinfo -g
| |
| − | smbtree
| |
| − |
| |
| − | ===Authentication Modifications===
| |
| − | {{Warning box| Altering the pam system authentication files can seriously effect your ability to login in to the system. Take a backup of the /etc/pam.d directory and /etc/nsswitch.conf. Have a live CD available to give access and re-apply the backup files if you make a mistake and/or get locked out}}
| |
| − | *Open and edit /etc/nsswitch.conf and find the hosts: line. Change it to
| |
| − | hosts: files dns wins
| |
| − | *Change to the auth-client-config tool profile directory
| |
| − | cd /etc/auth-client-config/profile.d
| |
| − | *Create and edit a new file called acc-sme, and enter
| |
| − | [sme]
| |
| − | nss_group=group: compat winbind
| |
| − | nss_netgroup=netgroup: nis
| |
| − | nss_passwd=passwd: compat winbind
| |
| − | nss_shadow=shadow: compat
| |
| − | pam_account=account [success=2 new_authtok_reqd=done default=ignore] pam_winbind.so
| |
| − | account [success=1 default=ignore] pam_unix.so use_first_pass use_authtok
| |
| − | account requisite pam_deny.so
| |

| |
| − | pam_auth=auth [success=2 default=ignore] pam_winbind.so

| |
| − | password [success=1 default=ignore] pam_winbind.so use_first_pass md5 use_authtok
| |
| − | password requisite pam_deny.so
| |
| − | password required pam_permit.so
| |
| − | password optional pam_gnome_keyring.so
| |
| − | pam_session=session [default=1] pam_permit.so
| |
| − | session requisite pam_deny.so

| |
| − | session optional pam_mount.so enable_pam_password
| |
| − | session optional pam_ck_connector.so nox11
| |
| − | {{Tip box| You can use
| |
| − | auth-client-config -S > acc-sme
| |
| − | to create the file first, containing the current pam files configuration, and then just modify}}
| |
| − |
| |
| − | (This did not work for me even as sudo. Manually created the file with touch sme-acc and then edited)
| |
| − |
| |
| − | *Save the file. Apply the pam authorisation changes
| |
| − | auth-client-config -a -p sme
| |
| − |
| |
| − | ===Modify Login Screen===
| |
| − | The default login screen for Ubuntu 12.04 LTS does not give the option to select “Other” users. This is required if we are to authenticate against SME Server users. To enable this option edit /etc/lightdm/lightdm.conf and add the following line
| |
| − | greeter-show-manual-login = true
| |
| − | ===Automount User Home Directories at Login===
| |
| − | cd /etc/security
| |
| − |
| |
| − | *Open and edit pam_mount.conf.xml file. Find the 'Volume Definitions' section. Add a volume line below the header
| |
| − | <nowiki><!-- Volume Definitions --> </nowiki>
| |
| − | <volume fstype="cifs" server="<SMESERVER>" path="homes" mountpoint="~/nethome" options="nosuid,nodev" />
| |
| − | *Replace <SMESERVER> above with the samba name of your SME Server. This will mount the users 'home' directory from SME Server into a directory called 'nethome' in their local home directory.
| |
| − |
| |
| − |
| |
| − | === Automount Ibays at Login===
| |
| − |
| |
| − | *Edit /etc/security/pam_mount.conf.xml and add a line below the header
| |
| − | <nowiki><!-- Volume Definitions --> </nowiki>
| |
| − | <volume sgrp="<GROUPNAME>" fstype="cifs" server="<SMESERVER>" path="<IBAYNAME>" mountpoint="~/<IBAYNAME>" options="user=%(DOMAIN_USER),setuids,acl" />
| |
| − | *Replace <SMESERVER> with the samba name of your SME server, <IBAYNAME> with the ibay name, <GROUPNAME> with the description of the ibay owner group. The description can be recovered with
| |
| − | wbinfo -g
| |
| − | {{Note box| The sgrp param is optional. If used, ibay will be mounted only if %(DOMAIN_USER) is a member of ibay's owner group}}
| |
| − |
| |
| − | === Give Domain Admins local admin rights ===
| |
| − |
| |
| − | *Edit /etc/sudoers and add the following line:
| |
| − |
| |
| − | # Allow "Domain Admins" from the SME Server domain to run all commands
| |
| − | %<WORKGROUP>\\Domain\ Admins ALL=(ALL) ALL
| |
| − |
| |
| − | *Replace <WORKGROUP> with your SME Server's Windows workgroup name.
| |
| − |
| |
| − | ===Login and Test===
| |
| − | *Exit the Terminal cli
| |
| − | *Reboot the machine.
| |
| − | *Login as a valid SME Server user on your system, just giving username and password. No need for DOMAIN\user as samba configured above to use the default Windows Workgroup
| |
| − | *Authentication against SME Server should proceed and the user log in. A home directory on the local machine should be created as /home/DOMAIN/user, and a sub directory to that called 'nethome' mounted to the users home directory on the SME Server.
| |
| − |
| |
| − | ===Login screen security===
| |
| − |
| |
| − | The list of available users shown at the login screen is cleared after each reboot. Once you have confirmed that everything is working you can, however, optionally configure the graphical login screen to hide the names of both local users and SME Server users who have recently logged in. This won't stop any serious attempt to break into a machine but is roughly equivalent to similar options available with the Windows XP login screen. Edit /etc/lightdm/lightdm.conf and add the following line
| |
| − | greeter-hide-users=true
