ISEPhone Instructions for iOS

You will be expected to have students in your Active Directory server.  Please follow the directions below to add them.

You will need the files AddUsersAD.ps1 and Users_CURRENT.csv, they are located in the scenario folder.

1. Log in as an Administrator on your Active Directory VM.
2. Download the files from the scenario folder
3. Open PowerShell in the current directory (type cd C:\%userprofile%\Downloads to get to the downloads folder)
4. Edit line 5 of the script and change team42 to teamN, where N is your team’s number.
5. Execute the PowerShell script .\AddUsersAD.ps1

Users should now be imported into Active Directory. Verify this by opening up the server manager and looking at the user list.
Note: you might need to modify the script to fit your need.

In a command prompt, navigate to the AdminScripts directory (probably C:\Inetpub\AdminScripts\) and run the following:

cscript adsutil.vbs set msftpsvc/DefaultLogonDomain teamN.isucdc.com

where N is your team number.

Using the LDAP plugin available for PAM, it’s possible to do LDAP authentication without joining the domain. Note however that this requires installing Identity Management for Unix on your domain controllers. See this tutorial for more information.

Before we proceed, it’s a good idea to take a snapshot. I’ll wait for you to do that.

Okay, let’s install the required packages:

apt-get install libnss-ldapd libpam-ldapd

Now edit /etc/nslcd.conf. This assumes the user you created for binding to AD is named “ldap”.

# /etc/nslcd.conf
# nslcd configuration file. See nslcd.conf(5)
# for details.

# The user and group nslcd should run as.
uid nslcd
gid nslcd

# The location at which the LDAP server(s) should be reachable.
uri ldap://teamN.isucdc.com

# The search base that will be used for all queries.
base dc=teamN,dc=isucdc,dc=com

# The LDAP protocol version to use.
ldap_version 3

# The DN to bind with for normal lookups.
binddn ldap@teamN.isucdc.com
bindpw <password>

# The DN used for password modifications by root.
# Leave this blank unless you want to allow password changes from your debian systems
# If so, you will need to place the password in /etc/ldap.secret - be sure it is only readable by root
#rootpwmoddn cn=admin,dc=example,dc=com

# The search scope.
scope sub

# Mappings for Active Directory
# This is the important bit; these fields match up with the fields added by Directory Services for UNIX
pagesize 1000
#referrals no
filter passwd (&(&(objectClass=person)(uidNumber=*))(unixHomeDirectory=*))
map    passwd uid              sAMAccountName
map    passwd homeDirectory    unixHomeDirectory
map    passwd gecos            displayName
# If you wish to override the shell given by LDAP, uncomment the next line
#map    passwd loginShell       "/bin/bash"
filter shadow (&(&(objectClass=person)(uidNumber=*))(unixHomeDirectory=*))
map    shadow uid              sAMAccountName
map    shadow shadowLastChange pwdLastSet
filter group  (&(objectClass=group)(gidNumber=*))
#map    group  gid              member

# SSL options
tls_reqcert never
#ssl start_tls
#ssl on
#tls_cacertfile /etc/ssl/ca.pem

After you edit this file, restart nslcd and nscd:

service nslcd restart
service nscd restart

Now edit /etc/nsswitch.conf:

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         files ldap
group:          files ldap
shadow:         files ldap

hosts:          files dns ldap
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis

Make sure LDAP authentication is enabled by running

pam-auth-update

In /etc/pam.d/common-session, add the following at the bottom of the file. This will make home directories for users that have never logged in before. Be careful – mis-editing PAM configuration could permanently lock you out of your system! Take a snapshot before proceeding.

# make home directories
session required   pam_mkhomedir.so skel=/etc/skel/ umask=0077

This umask will prevent users from reading each others’ home directories. If you’d prefer to be more open, use umask=0022 instead.

You can test this out by restarting sshd (service ssh restart) or by rebooting. If you managed to accidentally completely lock yourself out, revert to that snapshot you took earlier.

Using the LDAP plugin available for PAM, it’s possible to do LDAP authentication without joining the domain. Note however that this requires installing Identity Management for Unix on your domain controllers. See this tutorial for more information.

Before we proceed, it’s a good idea to take a snapshot. I’ll wait for you to do that.

Once that’s done, install the required packages:

pkg install nss_ldap openldap-client pam_ldap pam_mkhomedir (FreeBSD 10)

--or--

pkg_add -r nss_ldap openldap-client pam_ldap pam_mkhomedir (FreeBSD 9 and earlier)

These packages are going to require some configuration. First, edit /usr/local/etc/openldap/ldap.conf – all you should need to change are the BASE and URI lines:

# LDAP Defaults
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

BASE dc=teamN,dc=isucdc,dc=com
URI ldap://ad.teamN.isucdc.com

#SIZELIMIT 12
#TIMELIMIT 15
#DEREF never

The next bit is long but most of it will be commented out. You’ll need to edit /usr/local/etc/ldap.conf and /usr/local/etc/nss_ldap.conf. These files should be exactly identical – you can either copy one to the other or symlink one to the other; I’ll leave that up to you. Feel free to copy the entirety of the following. Alternatively, just modify the italicized lines.

Note: this assumes that the user account you made for ldap queries is named “ldap” – substitute whatever you named the account.

# switch library and the LDAP PAM module.

Whew! We’re getting there, next step is to modify /etc/nsswitch.conf – modify the group and passwd lines to include the “ldap” option:

Alright, now comes the hairy bit: PAM configuration. Pay close attention here – incorrect PAM configuration could permanently lock you out of your system! If you haven’t already, TAKE A SNAPSHOT NOW.

Alright, we’re on the home stretch now! Edit /etc/pam.d/sshd – this affects how users log in over SSH:

#
# $FreeBSD: release/10.0.0/etc/pam.d/sshd 197769 2009-10-05 09:28:54Z des $
#
# PAM configuration for the "sshd" service
#

auth            requisite       pam_opieaccess.so       no_warn allow_local
#auth           sufficient      pam_krb5.so             no_warn try_first_pass
#auth           sufficient      pam_ssh.so              no_warn try_first_pass
auth            required        pam_unix.so             no_warn try_first_pass

# account
account         required        pam_nologin.so
#account        required        pam_krb5.so
account         required        pam_login_access.so

account         required        /usr/local/lib/pam_ldap.so      no_warn ignore_authinfo_unavail ignore_unknown_user

account         required        pam_unix.so

# session
#session        optional        pam_ssh.so              want_agent
session         required        /usr/local/lib/pam_mkhomedir.so umask=0077
session         required        pam_permit.so

# password
#password       sufficient      pam_krb5.so             no_warn try_first_pass
password        required        pam_unix.so             no_warn try_first_pass

Note carefully the placement and exact syntax of the added lines (the pam_ldap.so and pam_mkhomedir.so bits). pam_mkhomedir will automatically make home directories for users that exist in LDAP but have never logged in. The umask sets permissions on these directories – 0077 corresponds to running “chmod 700 /home/username”. For a more relaxed setting, try 0022 instead – this will allow users to read from, but not write to, other users’s home directories by default.

Alright, that’s all the config files! Let’s test this out by restarting sshd:

service sshd restart

--or--

/etc/rc.d/sshd restart

Try logging in as a user you set up UNIX attributes for in Active Directory. This almost certainly isn’t going to work the first time – carefully go over the AD configuration and all the config files above before proceeding. If you’ve accidentally completely locked yourself out of SSH, you can still get in via the console – comment out the lines you added in /etc/pam.d/sshd and restart sshd again to regain access.

Once you’ve gotten everything working, reboot the box. Make sure everything still works and that you can log in. If you’re completely satisfied, you can also CAREFULLY edit /etc/pam.d/system – this file deals with logins to the console. This is optional and should only be attempted if you plan on logging in to the console with an AD account. If you’re unsure, don’t edit this file as an error in it will permanently lock you out of console logins!

Identity Management for Unix allows you do to things like authenticate against Active Directory from a *nix system using LDAP or other tools. Refer to this technet article for full instructions on installing the components; the synopsis is below. Afterwards you will need to set up some user and group attributes.

WARNING: It appears that Identity Management for UNIX has been removed in Server 2012 R2. While there are workarounds, they involve editing your Active Directory schema directly (which is dangerous) and are beyond the scope of this article.

In Server 2008/R2 do the following:

To install Identity Management for UNIX components

1. Open Server Manager. To open Server Manager, click Start , point to Administrative Tools , and then click Server Manager .
2. In the tree pane, expand Roles .
3. On the role home page for AD DS, in the Roles section, in the list of common tasks, click Add Role Services .
4. On the Select Role Services page of the Add Role Services Wizard, select the Identity Management for UNIX role services that you want to install, and then click Next .
5. If the wizard prompts you to install any other role services that are required by Identity Management for UNIX components, click Yes .
6. After verifying your selections on the Confirm Installation Selections page, click Install .The computer must be restarted after the installation of Identity Management for UNIX finishes.

In Server 2012 do the following:

Right-click Windows PowerShell and click Run as Administrator. Run each of the following commands:

• Dism.exe /online /enable-feature /featurename:adminui /all to install the administration tools for Identity Management for UNIX.
• Dism.exe /online /enable-feature /featurename:nis /all to install Server for NIS
• Dism.exe /online /enable-feature /featurename:psync /all to install Password Synchronization

A restart of the computer is required when you install Identity Management for UNIX.

Once you’ve done that, we’ll need to do some additional configuration. Open up Active Directory Users and Computers. Make a standard group for your *nix administrators. Then right-click the group and choose the UNIX Attributes tab:

Additionally, you’ll need to edit the properties of any user you plan on giving access to a *nix box. Open up Active Directory Users and Computers and right-click a user account, then select the UNIX Attributes tab:

Use the primary group you made earlier.

One last thing: You’ll need to make a standard user in Active Directory for your *nix systems to bind with in order to perform LDAP queries. This user doesn’t have to have any special permissions but it’s a good idea to check the “user can never change password” box when creating it.

After setting the proxy in internet options, you’ll have to run an additional command to get Windows Update working.

Open a command prompt and run the following:

netsh winhttp import proxy source=ie

You can verify this by running:

netsh winhttp show proxy

And if you want to reset it:

netsh winhttp reset proxy

VMware Tools is a package that can be installed on your Windows and Linux/BSD VMs that improves their performance, especially in graphics and networking.

Installation in Windows guests

Select the VM, and on the “Summary” tab you will see an option to install VMware Tools:

This will mount the CD image for you.

In the guest,  simply open up the CD drive and run the setup executable.

Generally, it’s safe to accept the default options. You’ll need to reboot once the installation is finished.

You’ll notice that the IP address of the VM now becomes visible in the Web Client, as well as some information about its resource usage:

Installation in Linux/BSD guests

Via the open-vm-tools package

VMware recommends you install the open-vm-tools package provided by your distribution, if it exists.

•  Debian/Ubuntu:

• apt-get install open-vm-tools

• Fedora/CentOS:

• yum install open-vm-tools

• openSUSE:

• zypper install open-vm-tools

• BSD:

• pkg install open-vm-tools-nox11 (for systems without a GUI)
  
  -- or --
  
  pkg install open-vm-tools (for systems with a GUI)

Manually from CD

Mount the CD by clicking “Install VMware Tools” as in the installation for Windows guests. You’ll probably need to install some packages to satisfy VMware Tools’ dependencies.

At minimum you will need:

• Perl (installed by default on many systems)
  • Debian/Ubuntu (usually already installed):

    apt-get install perl

  • Fedora/CentOS (usually already installed):

    yum install perl

  • openSUSE (usually already installed):

    zypper install perl

  • BSD:

    pkg_add -r perl5

• C compiler and appropriate header files
  • Debian/Ubuntu:

    apt-get install build-essential

  • Fedora/CentOS:

    yum groupinstall "Development Tools"

  • openSUSE:

    zypper install -t pattern devel_C_C++

• Kernel header files
  • Debian:

    apt-get install linux-headers-$(uname -r)

  • openSUSE:

    zypper install kernel-devel

• In FreeBSD guests, you will also need the “compat6x” package:

  pkg_add -r compat6x-i386 (32-bit)
  
  --or--
  
  pkg_add -r compat6x-amd64 (64-bit)
  

Now mount the CD drive. If your *nix installation has a GUI, this should be done automatically for you. Otherwise, run the following as root:

• Linux:

  mount /dev/cdrom /mnt

• BSD:

  mount -t cd9660 /dev/cd0 /mnt

Now copy the file to a temporary location, extract it, and run it:

cp /mnt/VMware-Tools*.tar.gz /tmp/
cd /tmp
tar -zxf VMware-Tools*.tar.gz
cd vmware-tools-distrib/
./vmware-install.pl

The installer will ask you a series of questions; accept the default options if you aren’t sure.
Once the installer is done, reboot.
