Managing RBAC Roles with RBAC_Manager, with Five easy steps.

Filed under: General — telnet25 @ 2:44 pm

We will look into using RBAC Manager R2 rom (CodePlex) to manage our environment. There are several cmdlet’s also available.

Download RBAC manager From this link , unzip the files and execute RBAC_Manager.exe.

Note: RBAC_Manager.exe runs into memory space , it means you do not have to install it. If your environment is “secured” this could be pretty neat news. I still recommend making sure , you are clear with your work place existing policies etc..

image

Now provide required parameters and click ok to connect.

image

You will be seeing Management Roles , listed on the left pane

image

*PS equivalent for what you are seeing would be

#Get all management Role Entries

Get-ManagementRoleEntry "*\*"

After making making up your mind what Management Role you like to use as parent and create new one, simply “right click” and select “New Role From Here”

image

*PS equivalent

If you like to see what cmdlet;s assigned to specific Role entry

Get-ManagementRoleEntry "Active Directory permissions\*"

image

Create new Role from Parent

New-ManagementRole "ZTEK Active Directory Permissions" -Parent "Active Directory Permissions"

image

Note: As far as name convention goes for the Management Roles, make some plans and follow them. Having simple name convention for Management roles and Role Groups will provide more simpler management to your organization.

image

image

Select the Role and get rid of any cmdlet you do not want to associate with this Role, Click Save on the top menu to save the changes.

image

PS Version ( Remove All cmdlet,  but Like ( matches ) the filter )

Get-ManagementRoleEntry “ZTEK Active Directory permissions\*” | Where {$_.name -Like “Get-User”} |  Remove-ManagementRoleEntry -Confirm:$False

Now Click on “Show Role Groups”

image

image

Get-RoleGroup

image

Create Role Group

New-RoleGroup -Name "ZtekZone HelpDesk 1.0"

image

image

here you can select any of the existing roles , custom scope options, it is pretty simple and useful , once you are read click on ok.

image

In this example I will pick up the role we have created earlier

image

Adding member to Role Group

image

image

image

Get-RoleGroup | Select-Object name

image

Get-RoleGroup -Identity "ZtekZone Security Tier 2"

image

Get-RoleGroup -Identity "ZtekZone Security Tier 2" | Add-RoleGroupMember -Member c-Aki.Armstrong

to see the list of members

Get-RoleGroup -Identity "ZtekZone Security Tier 2" | Select-Object name,members | ft -AutoSize

image

you can un-check the box to take Ron out of RBAC Role Group. As you already know RBAC groups are kept in the AD root Forest, in the “ Microsoft Exchange Security Groups” Organization container.

image

image

image

As you can see it is fairly simple to manage the RBAC roles and it is related task with RBAC Manager

Create Custom RBAC roles with quick powerfull cmdlets.

Filed under: General — telnet25 @ 1:49 pm

Here are some handy RBAC cmdlets to help you build your own custom Role Groups, role assignments etc. When you design RBAC Groups , you need to pay attention to your name convention to make sure , Groups, role assignments etc. makes sense, each Role Group created will be located on Microsoft Exchange Security Groups on the root of the forest/Domain , adding members to these security groups also possible using active directors users snap in, so you need to have plan to secure these groups. it might be good idea to tick the box “protect object from accidental deletion” for these groups.

#List all Management Roles

Get-ManagementRole

clip_image001

#List all role entries within given Management Role

Get-ManagementRoleEntry "View-Only Recipients\*"

clip_image002

Note: as you have noticed, all these cmdlet’s , user can run if the user is assigned to a Role Group = Assigned Role = ManagementRoleEntry

Here is simple snapshot to digest the relationship

clip_image003

#Create new Role from existing Parent Role

New-ManagementRole "HelpDesk Permissions" -Parent "View-Only Recipients"

clip_image004

#Remove all Role Entries , except selected one

Get-ManagementRoleEntry “HelpDesk Permissions\*” | Where {$_.name -ne “Get-User”} | Remove-ManagementRoleEntry -Confirm:$False

image

#Locate managementRole

Get-ManagementRoleEntry “HelpDesk Permissions\*”

clip_image006

#Add additional CMDLET if needed to management Role

Add-ManagementRoleEntry “HelpDesk Permissions\Get-MailboxPermission”

clip_image007

#Locate ManagementRole to verify desired cmdlet is assigned to it

Get-ManagementRoleEntry “HelpDesk Permissions\*”

clip_image008

#Create New Role Group

New-RoleGroup "HelpDesk 1.5"

clip_image009

#Add Role assignment to Role Group

New-ManagementRoleAssignment -SecurityGroup "HelpDesk 1.5" -Role "HelpDesk Permissions"

clip_image010

#add member to Role Group

Add-RoleGroupMember “HelpDesk 1.5” –Member C-Ron.Buzon

clip_image011

#locate members

Get-ManagementRoleEntry “HelpDesk Permissions\*”

clip_image012

#remove Members from desired Role Group

Remove-RoleGroupMember “HelpDesk 1.5” –Member C-Ron.Buzon

# Find desired user, List all the Roles

Get-ManagementRoleAssignment -GetEffectiveUsers | ?{$_.EffectiveUserName -eq “Administrator”} | select Role

How To Create CUSTOM RBAC ROLE Exchange 2010 & 2013

Filed under: General — telnet25 @ 8:53 pm

We would like to utilize RBAC Role model and create custom RBAC Role for specific needs for a business. These needs could be different from one environment to another. This article will be good reference for you to get your customization. Having said that, first thing to understand is the RBAC Layers.

There are 6 Layers which make up the Role Group Model

  • Role group member
  • Management role group
  • Management role assignment
  • Management role scope
  • Management role
  • Management role entries

clip_image001[4]

Goal:

  1. Create Custom Role Group
  2. Create Custom RBAC Role Entry with desired cmdlet’s
  3. Add Custom Role entry to Role
  4. Add role to Custom Role Group
  5. Add Members to Custom Role Group

In this example we will use following template

image

Note: You can build your own management Role , and modify management role entries same way in this article. The process is pretty straight forward.

Task#1

Figure out all role entry contains set-mailbox (set-mailbox is one of the cmdlet we have as our requirement)

Get-ManagementRoleEntry *\Set-Mailbox

clip_image002[4]

 

Task#2

Create the management role with related parent Role

New-ManagementRole -Name “Assign Mailbox Access” -Parent “Mail Recipients”

clip_image003[4]

Task#3

Get-ManagementRoleEntry "Assign Mailbox Access\*"

Verify all cmdlet assign to newly created management role, as you can see we have many cmdlet we don’t want, therefore we will need to remove most of them and only keep what we need.

clip_image004[4]

Task#4

Remove what you don’t need

Get-ManagementRoleEntry “Assign Mailbox Access\*” | Where {$_.name -ne “Add-MailboxPermission”} | Remove-ManagementRoleEntry -Confirm:$False

clip_image005[4]

Task#5

Verify the Role entry , minimum cmdlet is assigned.

clip_image006[4]

Task#6

Add additional cmdlet

  • Add-ManagementRoleEntry "Assign Mailbox Access\get-mailbox"
  • Add-ManagementRoleEntry "Assign Mailbox Access\get-mailboxPermission"
  • Add-ManagementRoleEntry "Assign Mailbox Access\remove-mailboxPermission"
  • Add-ManagementRoleEntry "Assign Mailbox Access\set-mailbox"

clip_image007[4]

Task#7

Add remove any role entries if desired

Verify one more time to make sure we have all we wanted. If required continue to add by using same one liner cmdlet

Add-ManagementRoleEntry "Assign Mailbox Access\set-mailbox" —————> you can replace set-mailbox

If you need to remove use

Remove-ManagementRoleEntry "Assign Mailbox Access\set-mailbox"

clip_image008[4]

Task#8

Create new Role Group

New-RoleGroup “Audit Team”

clip_image009[4]

Task#9

Let’s put them together

New-ManagementRoleAssignment -SecurityGroup "Audit Team" -Role "Assign Mailbox Access"

clip_image010[4]

Task#10

Add-RoleGroupMember “Audit Team” –Member C-Ron.Buzon

clip_image011[4]

We are done lets look at this from ECP

clip_image012[4]

clip_image013[4]

Now if c-ron.Buzon logs in, he will only get the cmdlets assigned to him via RBAC Role. As you can see RBAC permissions model is very efficient and effective. When creating Roles, group and Role entries, you may want to think about unifying name convention and plan this out before start implementing it into production environment.

Installing First Windows 2012 Domain Controller into Existing Forest/Domain via PowerShell

Filed under: General — telnet25 @ 7:54 pm

 

Task: Introducing first Windows 2012 domain controller into Existing Forest /Domain. As you already  notices with Windows 2012 , promoting server to be additional domain controller is changed a lot. There is no more DCpromo instead we use GUI or PowerShell to get the work done.

High Level Steps :

  • Install Windows 2012 Server
  • Configure , Server name, IP address
  • Add Server into existing domain as member server ( preferred )
  • Use PS to promote the server to be additional domain controller and modify the DCpromo.ps1 Script

Step# 1

First task is to add the windows 2012 server into existing domain. Adding server into existing domain  before promoting to be domain controller is a good old habit ,  which allows A record to be created  within the existing DNS Forward lookup  zone and helps also ensures correct DNS settings has been configured.

Log into Server

Open PowerShell and type following command.

Install-WindowsFeature -Name Ad-Domain-Services | Install-WindowsFeature

clip_image001

Step# 2

Now copy and paste the , below PowerShell command into notepad , and save it as DCpromo.ps1 ( we use this name to honor DCPromo we have used ages (-:   , you can name it anything you like.

image

You will need to change  “-DomainName "ZtekZone.com"  and if you like any additional customization , such as changing the defaults , SYSLOG, DatabasePath, LogPath etc.

Download the script from here

Run PS Command against pre-defied PS Script

#Installing Domain Controller

Write-Host "………………………….."

Write-Host "Please modify pre defined Script "

Write-Host "To Make sure it fits into your Environment"

Write-Host "………………………….."

Import-Module ADDSDeployment

Install-ADDSDomainController `

-NoGlobalCatalog:$false `

-CreateDnsDelegation:$false `

-CriticalReplicationOnly:$false `

# Change the DatabasePath if desired

-DatabasePath "C:\Windows\NTDS" `

# Change the Domain name if desired

-DomainName "ZtekZone.com"

-InstallDns:$true `

# Change the LogPath if desired

-LogPath "C:\Windows\NTDS" `

-NoRebootOnCompletion:$false `

# Change the AD Site Name if necessary

-SiteName "Default-First-Site-Name" `

# Change the SYSVOL if necessary.

-SysvolPath "C:\Windows\SYSVOL" `

-Force:$true

Now after modifying the script save it onto server into temp Directory

image

From PowerShell Run it

clip_image002

clip_image003

clip_image004

After server reboot if we open Site and Services we will see the additional domain controller

clip_image005

Now couple additional Configuration we will perform on the new domain controller

Add-WindowsFeature RSAT-AD-PowerShell, RSAT-AD-AdminCenter

clip_image006

Now you can open ADAC from GUI

clip_image007

Or you can open it from PowerShell

clip_image008

clip_image009

You can also open Site and Services

dssite.msc

clip_image010

You can open ADUC

Dsa.msc

clip_image011

Installing Windows 2012 Core as additional Domain Controller into Existing Forest/Domain. Sconfig is your Friend.

Filed under: General — telnet25 @ 7:46 pm

 

After finishing window 2012 server install , and logging into server all we get is  plain command prompt. If you are tasked to promote this newly installed  Core Server to be the additional domain controller you can use Sconfig to get the mission accomplish.

Type “Sconfig” and hit enter

image

image

Now first thing we will do is to rename the server

Option # 1

image

 

image

we will say no to this one for now, we will set the IP Address

Option # 8

image

Type the index number shown on the menu for the adapter you wish to configure

image

Option # 1

and select Static ( S )

image

as you can see the new configured IP is showing up next to 169.254.1.121

Now we need to take care of  DNS IP Addresses

Option # 2

image

image

image

Option # 4 return the Main Menu

image

Enable RDP Option # 7

image

and now I am going to re-start the server

image

After I login I made sure I can ping my existing DC/GC/DNS Server

image

Firing up SConfig one more time to add the server into existing domain as member server

image

image

Now server is part of the domain and ready to be promoted as additional domain controller

I make sure to log back into domain

image

Now lets fire-up PowerShell

image

image

Fire-up Sconfig  one more time to make sure I have the correct, desired configuration settings.

image

 

Install-WindowsFeature -Name Ad-Domain-Services | Install-WindowsFeature

image

Type notepad.exe on the PS and hit enter

image

Copy and paste below code into notepad.

Core.ps1 ( You need to change the desired filed in the PS script , such as domain name

I have used “-DomainName "ZtekZone.com" change this to suit to your scenario. Once you are done, on the notepad click file and save as , and save the file on the C:\temp directory as “CoreDeploy.ps1”

image 

You can download the script from here

image

 

#Installing Domain Controller

Write-Host "………………………….."

Write-Host "Please modify pre defined Script "

Write-Host "To Make sure it fits into your Environment"

Write-Host "………………………….."

Import-Module ADDSDeployment

Install-ADDSDomainController `

-NoGlobalCatalog:$false `

-CreateDnsDelegation:$false `

-CriticalReplicationOnly:$false `

# Change the DatabasePath if desired

-DatabasePath "C:\Windows\NTDS" `

# Change the Domain name if desired

-DomainName "ZtekZone.com"

-InstallDns:$true `

# Change the LogPath if desired

-LogPath "C:\Windows\NTDS" `

-NoRebootOnCompletion:$false `

# Change the AD Site Name if necessary

-SiteName "Default-First-Site-Name" `

# Change the SYSVOL if necessary.

-SysvolPath "C:\Windows\SYSVOL" `

-Force:$true

Now within the PS , change the directory to C:\temp directory

image

 

Type “CoreDeploy.ps1”

image

 

image

ZtekZone.com ( is the domain name in my case)

image

image

After server reboots , you need to make sure replication is working etc.

here is AD site and services with the newly promoted server

Configuring Servers with /32 Subnet Mask

Filed under: General — telnet25 @ 11:15 am

There are times specific IP address explicitly needs to be added into Active Directory site and services to ensure the application or the servers is talking to specific domain controllers for certain task such as authentication, Global catalog selection etc. Very recent ExRAP program I have worked , indicated some of the Exchange servers were talking to domain controllers out of its own AD SITE. As you may already know Exchange servers will select DC/GC from their own AD Site and if they cannot reach them out they will try to communicate other available domain controller ( DC/GC) the magic lays down on how TCP/IP settings configured on the client as well as AD Site and services , subnets.

In this example we will add Exchange server IP Addresses is  10.10.10.121 /24

On  the domain controller we will open Site and Services snap in

DSSite.msc 

image

Click Subnets , new subnet , type the IP address and Subnet mask and select the corresponding ( desired)  AD Site.Once finish you can make right click on Site and make sure the IP address is added on the properties.

image

image

By doing this simple task, we made sure the very specific IP address and its subnet mask is added to AD Site we choose.
