In the previous blog we learned about what is coming new in Exchange 2.In this blog we will review the Exchange 2.Exchange Server 2.All You Need to know Part 1.Exchange Server 2.All You Need to know Part 3.Exchange 2. 01. 6 Architecture.How To Install Adfs 2 0 Proxy Sites' title='How To Install Adfs 2 0 Proxy Sites' />These are the declarations from Ignite and subject to change at the time of RTM release.Primary Changes. Edge Transport is coming with RTM So yes most of you guessed correct in the NY Exchange User Group on our Exchange Edge Session.Client Access Server merged with mailbox role server so its just mailbox server role and Edge Transport Role.New Office Web Apps Server coming up It is a new server which allows attachment editing in OWA.This is optional server and not a necessity.Data rendering and client connection will occur locally on the server where mailbox exist.In other words connection will be proxy or redirect to the mailbox owner server.Topology Requirement.Exchange 2. 00. 7 will not be supported in the co existence.So we can say bye to Exchange 2.Exchange 2. 01. 0 SP3 RU1.Exchange 2. 01. 3 CU1.Exchange 2. 01. 6 should be installed on Windows 2.R2 and windows server 1.DAG should be able to support IPLess DAG.Forest and Domain functional level should be windows 2.R2 or later. This means domain controllers should be higher than windows 2.R2. No windows 2.You need to upgrade them or demote them.Outlook clients should be the following or higher.Outlook 2. 01. 0 SP2 or later with KB2.KB2. 96. 52. 95 These patches provides MapihttpOutlook 2. Corel Draw X3 Sp2 Portable Ac . SP1 or later with KB3.This patch fixes shared mailbox and legacy Public Folders Mailbox Server Role will do the following.Authenticate Clients Do a directory look up.Determine the mailbox version.Location of the mailbox database.Decision on proxy or redirect.Also determine how store process and data rendering.Mailbox Server Role Changes.Only IP Less DAGStill 1.Still 1. 00 DB copies per server.Still ESE Database engine.Replay lag manager will be enabled by default which means if we have 2 passive database copies then 3rd passive database copy will be Lag copy which will not require to be enabled.Similar in case of losing one database copy lag copy will automatically commit the logs and become 2nd passive copy.New IO latency monitor will be monitoring disk IO and dont replay the logs in case lag copy requires to replay the logs.Database failovers will be 3.Indexing Improvement Indexing search for the passive database copy will be done locally through passive database copy.Before Exchange 2.Index which has consumed lot of CPU and network bandwidth.Have a look into the indexing architecture.Office Web Apps Server Role provides the following Content rendering for MS office attachment files.Rich browser viewing.Side by side viewing and editing of attachment in OWA.Pulling the attachments from share point.MAPICDOTime to say bye to MAPICDO.Blackberry 5x will not work.Any app uses MAPICDO would needed to be updated Client Protocol Architecture MAPIHTTPMicrosoft introduced in Exchange 2.SP1. In Exchange 2.SP1 it used to be disabled.In Exchange 2. 01.In Exchange 2. 01.In Exchange 2. 01.We will also be able to control if autodiscover should expose Mapihttp configuration or not.Pop up administrator has made some changes so restart outlook will not come.It will wait for the user to restart outlook.Remove RPC stack dependency which means no RPC over http.More reliable connection and faster connection with hibernation feature.Improved diagnostics.MapiHttp connectivity architecture will be following Connectivity Flow in Exchange 2.Co existence with 2 AD Sites.It will be same as Exchange 2.Exchange 2. 01. 0 in the same AD site Proxy.Exchange 2. 01. 0 in the different AD site Proxy.Exchange 2. 01. 0 in the different AD site Redirect Connectivity Flow in Exchange 2.Co existence with 2 AD Sites same flow either Exchange 2.Exchange 2. 01. 3 in the same AD site Exchange 2.AD site Proxy Exchange 2.AD site Silent Redirect Use Form based Authentication on both source and destination Outlook Web Apps Server Connectivity Flow Optional Server.Exchange will use discovery URLsimilar to autodiscover url to query Outlook Web Apps Server what are the file types it can view and edit.Outlook Web Apps Server replies table of supported file types like MSword, MSExcel, MSOne.Note, etc. User opens email with attachment that matches one of the file types Outlook Web Apps Server supports and OWA requests document URLs for supported types.Exchange builds URL with Authentication token, app URL, and Attachment ID then reply it to OWAUser clicks attachment within Outlook Web App and responds an iframe to load the URL returned by Exchange.Outlook Web Apps Server pulls document content from Exchange.Outlook Web Apps Server renders content in Outlook Web Apps Server client Exchange Namespace.Microsoft has recommended to have separate namespace internalurl and externalurl for outlook anywhere and mapihttp so that separate authentication can be used for intranet Kerberos and internet NTLM or Basic connection.But it is only useful when we have internalurl which in not available on Public DNS.I have explained namespace requirement here.Unbound namespace can be used to provide CAS connection high availability to avoid internet outage by configuring DNS round robin for 2 datacenter IPs for the same CAS URL which is same as Exchange 2.Exchange 2. 00. 7 does not support unbound namespace in 2 AD sites but Exchange 2.Exchange 2. 01. 3 cant be install in an ORG with Exchange 2.Unbound Model is a preferred model.Exchange Load Balancing.No Session affinity required at Load Balancer Layer because it is taken care by mailbox server hosting the mailbox.Ensure Load Balancer and Managed availability should be knowing what they are doing to each other.Healthcheck. htm is helping in identifying if protocol is up or down.It is recommended to use 2 Load balancer type Round Robin mapihttp does not see any issue but RPC over http might have issue with long connections or Least Connections should use slow start feature.Preferred is Least connections with slow start feature.Single namespace Layer 7 is preferred no session affinity and recommended because one protocol will allow remaining protocols.SSL termination at LB would be required.If you need to use layer 4 then you should use multiple namespace.LB will not stop other protocol connections if one protocol fails.This will increase SAN names in the cert and its cost will go high.This is not recommended.Outlook Web App Server Namespace and Load Balancing.Deploy separate namespace.Follow a bound namespace model for site resilience.Load Balancer Persistence is required.Exchange will connect to the local AD site Outlook Web App Server Exchange 2.Preferred Architecture.For Exchange Single namespace for both datacenters should be used.Autodiscover. domain.Mail. domain. com.For OWAS deploy 1 namespace per datacenter.Load Balancer Configuration.For Exchange VIP One VIP Layer 7 per datacenter with no session affinity and per protocol health check.For OWAS VIP Session Affinity.DNS host entries in the Public DNS for round robin connectivity and equally distribution of clients to both the datacenters.Every datacenter should be a separate AD site so DAG should expended to 3 AD Sites.Dont stretch AD site because safety net keep shadow copy on a mailbox server in the 2nd AD site.Unbound namespace.Symmetric DAG model with same number of servers in each datacenter and same number of database copies in each datacenter.IP less DAG No Administrative Access PointReplication and Client connectivity through single network.File share witness in the 3rd DatacenterAzure.Distribute active copies to all DAG nodes.Passive datacenter with 1 lag copy7 days with automatic log play down.Use Native Data Protection which will eliminate the need of 3rd party backup.Dual socket systems only Total 2.Up to 1. 96.

Wow, thats a pretty long title Theres a lot of moving parts involved with this setup but ultimately you will have a more secure environment with a better user experience in my opinion.The Table of Contents is below, I would urge you to read why you should consider this setup for your environment and watch the videos I have created before jumping into the technical portions of this guide or its very easy to get lost with some of these concepts.A few years ago I gave you a brief introduction to SAML Security Assertion Markup Language claims based authentication and AD FS 3.Citrix Share. File http www.Since then I have seen more and more Enterprises wanting to integrate SAML authentication into all sorts of applications in their companies specifically for single sign on use cases.Using a combination of Net.Scaler Unified Gateway, Citrix FAS, and a SAML Id.P like AD FS, you can achieve single sign on for Citrix Xen.App, Xen. Desktop, and Store.Front as well. Were at a point where users have too many passwords to remember.Ive had discussion with some non IT people in different verticals and its the same story every time, they have to remember 1.Some are resorting to their own password management through the use of mobile password safes or online password manager services.Others are taking the old approach of writing down their credentials with paper and pen in notebooks, or worse saving them.IT staff are just as guilty of this.I cant tell you how many times Ive walked into an organization with a secure share for IT containing an IP spreadsheet and several.If an attacker was to gain access to that share, you have just saved them a ton of work having to scan and document your environment.Your IP spreadsheet shows every server and what it does plus they have the passwords now.Many high profile hacks in recent years were enabled by bad processes.From an operational standpoint, how many hours are spent by help desks all over the world resetting peoples passwords for them for all the various systems they accessAn organizations perimeter these days is actually pretty hardened through the use of advanced firewalls, content filters, reverse proxies, IDS, IPS, etc.Youll notice scans against your external firewalls but for the most part, they are just probing.The real threat to enterprises these days are the users, not the systems.Users are human, they make mistakes.They are not always as mindful as an IT person, heck half the time IT isnt.This is why spear phishing and other attacks against the end user are so successful vs.That attacks are coming from within the organization, and in some cases dont even originate on the organizations network So how do we protect the organizations network from end user originated attacks while still making the systems easy to use This is where SAML authentication whether on premises or in the cloud with single sign on to all systems the user uses begins to help.Added bonus it saves countless man hours in password reset calls to the help desk.Couple that with multi factor authentication depending on where the user is connecting from and youve just taken the first steps to help mitigate a lot of the problems many enterprises and their users are facing.If you saw the latest CUGC Networking Special Interest Group SIG presentation, you saw Dave Brett fellow CTP and myself talk about different cloud authentication options for your Citrix environment using Net.Scaler. If you missed it the webinar recording is here https www.I referenced Daves excellent 6 part series on using AD FS 3.Net. Scaler Unified Gateway you can read here http bretty.With this approach you gain quite a few benefits over a traditional Citrix deployment SAML auth all the way through your Citrix environment.Use a single FQDN internal and external with Net.Scaler Unified Gateway.Multi factor authentication for external users with logic on AD FS rather than Net.Scaler. Eliminating the need for AD FS WAP servers in the DMZIntegrated windows authenticationsingle sign on IWASSON for internal users.SSO ability into all your other Saa.S web applications.If using AD FS logins with Office 3.HDX Insight data gathered in Net.Scaler MAS for all this traffic.I wanted to switch my own environment from using AD FS 3.Server 2. 01. 2 to the newer AD FS 4.Server 2. 01. 6 as well as use the Rf.Web. UI theme with my Unified Gateway.I also wanted to integrate some of my existing Azure MFA infrastructure with AD FS rather than having it all on the same server and this required a bit of extra setup.This guide is going to show you a lot of what Dave has documented as well as a few things Ive done to get this working the way I wanted in my environment.Ill go over some of the challenges you might face if attempting to do the same in your environment.Ultimately you can make it all work and its a very polished user experience Lets get started examining the user experience first and then work our way into the how to sections.Videos of the user experience.This is what youre really here for so let me show you the 2 videos first so you can decide if this is the right approach for your company.Internal user experience External user experience Installing AD FS 4.Windows Server 2.AD FS 4. 0 is a server role.Go to the Add Roles and Features Wizard and hit Next.Next. 3. Next. 4.Choose Active Directory Federation Services and hit Next.Next. 6. Next. 7.Now hit Install. Configuring your AD FS 4.Federation Farm. 8.Once its done, click the Configure the federation service on this server link.Since this is the first server in the farm click Create the first federation server in a federation server farm option and hit Next.You will also notice it asks if you are configuring single sign on for Office 3.AD FS wizard and install Azure AD Connect.These days when people decide to migrate to Office 3.AD FS in that kind of setup.For what were using AD FS for however, internal and external authentication with Net.Scaler Gateway rather than the cloud, we need AD FS so ignore this message and keep going.Choose a domain administrator account to perform the AD FS configuration.Dont worry, you dont need to specify an elevated service account here.That comes later.Just enter your domain admin credentials, its only used to do the config.Import your SSL Certificate you intend to use with AD FS.Most companies I see are using something like adfs.You can pick whatever domain you like.I encourage you to use a standard single domain certificate in a production environment rather than a wildcard or SAN certificate.Sure it will work with any but there are some security implications you need to be aware of.More on this later.Specify your AD FS service account here.No special permissions required, just a regular service account with no group membership is all it needs.You can specify a SQL Server database please ensure you have a solid SQL environment first or you can use the Windows Internal Database WID.This will hold the AD FS Configuration Database.Using WID is fine in dev environments but if doing a production environment the recommendation is to use SQL please verify you have a solid SQL environment first.There are limitations on the number of nodes in your AD FS farm and the number of relaying parties allowed when using WID vs.SQL so its better to use SQL.This will prevent headaches later as your company grows.Next. 15. Verify the pre reqs check goes green and then hit Configure.Once completed it should show a green check saying the server was successfully configured.Creating an AD FS 4.Relying Party Trust with Net.Scaler Unified Gateway.Hit Start and right click on the AD FS Management console.Hit Pin to Start since youll be using it a lot.Now click the new icon to launch the console.Right in the center there is a link saying Required Add a trusted relying party.Click it. 2. 1. Select Claims aware and hit Start.Enter data about the relying party manually.Give it your Unified Gateway URL and add some notes if you like.Dont configure a cert, just hit Next.Check support for SAML 2.Web. SSO protocol and give it the URL.For the Relying party trust identifier, its a good idea to add both gw.
