Azure Stack WAP Connector - Part 1

Artigo
08/04/2017

Azure Stack WAP connector is preview now. With WAP Connector, you can enable access from the Azure Stack user portal to tenant virtual machines running on Windows Azure Pack. Tenants can use the Azure Stack portal to manage their existing IaaS virtual machines and virtual networks. These resources are made available on Windows Azure Pack through the underlying Service Provider Foundation (SPF) and Virtual Machine Manager (VMM) components. For more information about WAP connector, please refer to the link below.
https://docs.microsoft.com/en-us/azure/azure-stack/azure-stack-manage-windows-azure-pack

When we deployed WAP connector, the most challenging part is integrate the identity management systems between WAP and Azure Stack. Right now we support the following ID management scenarios.

Azure Stack Id Manager	CPS/WAP Id Manager	Notes
AAD	AD-ADFS	AD is synchronized with AAD
	AAD through ACS	CPS using AAD instead of local
	3rd Party Id Manager	Both sharing AAD
ADFS	AD-ADFS	Both sharing same customer AD
	AAD through ACS	Both sharing same AAD
	3rd Party Id Manager	Both sharing 3rd Party solution

If you're using ASDK, you probably would find it's more challenging coz in ASDK (one-node deployment) the whole Azure Stack is behind NAT.

In this blog, I will demonstrate how to integrate ASDK and WAP's identity management systems. In my setup, Azure Stack uses built-in ADFS (adfs.local.azurestack.external) and WAP uses a separate ADFS (fs.blue.cloud).

Pre-requisites

Deploy Azure Stack Development Kit (ASDK) and use ADFS type. https://docs.microsoft.com/en-us/azure/azure-stack/azure-stack-run-powershell-script#deploy-the-development-kit
Prepare a Separate AD forest (BLUE.CLOUD in my setup).
Deploy a WAP environment. In my setup, I put all the WAP roles on single VM (BLUE-WAP.BLUE.CLOUD). I hosted VMM and SPF are on another VM (BLUE-VMM.BLUE.CLOUD)

Prepare Certificates for *.BLUE.CLOUD

1. On BLUE-WAP.BLUE.CLOUD, run the following cmdlets to install CA.

 Install-WindowsFeature -Name ADCS-Cert-Authority -IncludeAllSubFeature -IncludeManagementTools

2. Open Server Manager and following the wizard to configure the CA as standalone CA.

3. Create certificate request configuration file called "Bluecloud-Cert.inf".

 [Version] 
Signature="$Windows NT$"

[NewRequest] 
Subject = "CN=*.blue.cloud"   ; For a wildcard use "CN=*.CONTOSO.COM" for example 
; For an empty subject use the following line instead or remove the Subject line entierely 
; Subject = 
Exportable = TRUE                  ; Private key is not exportable 
KeyLength = 2048                    ; Common key sizes: 512, 1024, 2048, 4096, 8192, 16384 
KeySpec = 1                         ; AT_KEYEXCHANGE 
KeyUsage = 0xA0                     ; Digital Signature, Key Encipherment 
MachineKeySet = True                ; The key belongs to the cph01 computer account 
ProviderName = "Microsoft RSA SChannel Cryptographic Provider" 
ProviderType = 12 
SMIME = FALSE 
RequestType = CMC

; At least certreq.exe shipping with Windows Vista/Server 2008 is required to interpret the [Strings] and [Extensions] sections below

[Strings] 
szOID_SUBJECT_ALT_NAME2 = "2.5.29.17" 
szOID_ENHANCED_KEY_USAGE = "2.5.29.37" 
szOID_PKIX_KP_SERVER_AUTH = "1.3.6.1.5.5.7.3.1" 
szOID_PKIX_KP_CLIENT_AUTH = "1.3.6.1.5.5.7.3.2"

[Extensions] 
%szOID_SUBJECT_ALT_NAME2% = "{text}"
_continue_ = "dns=*.blue.cloud&"
_continue_ = "dns=enterpriseregistration.blue.cloud&"
_continue_ = "dns=fs.blue.cloud&"
_continue_ = "dns=certauth.fs.blue.cloud&"
%szOID_ENHANCED_KEY_USAGE% = "{text}%szOID_PKIX_KP_SERVER_AUTH%,%szOID_PKIX_KP_CLIENT_AUTH%"

[RequestAttributes]

4. Run the following cmdlets and submit a certificate request.

 cmd.exe /c "certreq -new Bluecloud-Cert.inf Bluecloud-Cert.req"
cmd.exe /c "certreq -submit Bluecloud-Cert.req"

5. Open CA management console and issue the certificate and then copy it to the file "C:\Bluecloud-Cert.cer"

6. Run the following cmdlets and import the certificate to the local machine.

 cmd.exe /c "certreq -accept Bluecloud-Cert.cer"

7. Export certificates.

 $cert = get-Childitem cert:\localmachine\my | where-object {$_.Subject -eq "CN=*.blue.cloud"}
$PfxPass = ConvertTo-SecureString "123" -AsPlainText -Force
Export-pfxCertificate -Cert $cert -FilePath c:\Bluecloud-Cert.pfx -Password $PfxPass
$CAcert = Get-Childitem cert:\localmachine\root | where-object {$_.Subject -eq "CN=blue-BLUE-WAP-CA"}
Export-Certificate -Cert $CAcert -FilePath c:\Bluecloud-CACert.cer

8. Configure all the Web Sites on BLUE-WAP to use the new certificate.

 Import-Module WebAdministration
$sslBindings = Get-childItem IIS:\SslBindings\
$sslBindings | foreach-Object{$path = "IIS:\SslBindings\" + $_.IPAddress.IPAddressToString + "!" + $_.port; Remove-Item $path; $cert | new-item $path}

Install ADFS in Domain "BLUE.CLOUD"

1. On the domain controller "BLUE-DC.BLUE.CLOUD", copy the above "bluecloud-cert.pfx" and "bluecloud-CAcert.cer" to the folder "C:\". Then run the following cmdlets to install and configure ADFS.

 Install-WindowsFeature -Name ADFS-Federation -IncludeAllSubFeature -IncludeManagementTools

# Set these values:
$domainName = 'blue.cloud'
$adfsPrefix = 'fs'
$username = 'administrator' 
$password = 'User@123'
$dnsName = ($adfsPrefix + "." + $domainName)
$PfxPass = ConvertTo-SecureString "123" -AsPlainText -Force
$securePassword = ConvertTo-SecureString -String $password -Force -AsPlainText
$adfsServiceCredential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList ($domainname + '\' + $username), $securePassword

Import-Certificate -FilePath C:\Bluecloud-CACert.cer -CertStoreLocation cert:\localmachine\root 
$cert = Import-pfxCertificate -FilePath C:\Bluecloud-Cert.pfx -CertStoreLocation cert:\localmachine\my -Exportable -Password $PfxPass

# Configure AD FS
Install-AdfsFarm `
    -CertificateThumbprint $cert.Thumbprint `
    -FederationServiceName $dnsName `
    -ServiceAccountCredential $adfsServiceCredential `
    -OverwriteConfiguration

Set-ADFSProperties -IgnoreTokenBinding $True
Set-ADFSWebConfig –HRDCookieEnabled $false
cmd.exe /c "setspn -U -S http/fs.blue.cloud administrator"
cmd.exe /c "setspn -U -S http/blue-dc.blue.cloud administrator"

Configure the Name Resolution between Azure Stack and WAP

On ASDK Host Machine, open DNS management console and connect to AzS-DC01.AZURESTACK.LOCAL.
Add a conditional forwarding and forward the query for domain "BLUE.LCOUD" to IP address of the DNS server "BLUE-DC.BLUE.CLOUD".
On BLUE-DC.BLUE.CLOUD, open DNS management console and add a new DNS zone called "LOCAL.AZURESTACK.EXTERNAL".
Add an HOST record (A record) under that new created DNS zone "ADFS.LOCAL.AZURESTACK.EXTERNAL" and point to the external IP of AzS-BGPNAT01.

Configure the Trust between WAP Tenant Portal, Azure Stack's ADFS and BLUE.CLOUD's ADFS

1. On ASDK Host machine, create a text file "C:\Rules.txt". Copy and paste the following content to that file.

 @RuleTemplate = "LdapClaims"
@RuleName = "LDAP UPN"
c:[Type == "https://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname", Issuer == "AD AUTHORITY"]
 => issue(store = "Active Directory", types = ("https://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn"), query = ";userPrincipalName;{0}", param = c.Value);

@RuleTemplate = "LdapClaims"
@RuleName = "LDAP Groups"
c:[Type == "https://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname", Issuer == "AD AUTHORITY"]
 => issue(store = "Active Directory", types = ("https://schemas.xmlsoap.org/claims/Group"), query = ";tokenGroups(domainQualifiedName);{0}", param = c.Value);

@RuleTemplate = "PassThroughClaims"
@RuleName = "Passthru UPN"
c:[Type == "https://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn"]
 => issue(claim = c);

@RuleTemplate = "PassThroughClaims"
@RuleName = "Passthru Groups"
c:[Type == "https://schemas.xmlsoap.org/claims/Group"]
 => issue(claim = c);

3. Copy Bluecloud-CACert.cer to the ASDK Host machine's C drive.

4. Open GPMC.MSC and edit default domain policy. Import Bluecloud-CACert.cer to the Root CA store in that GPO.

5. On ASDK Host machine, run the following cmdlets.

 #Save Azure Stack's ADFS Metadata
