Cross Cutting Concerns for SharePoint 2013

Overview:  Last week I was speaking to a smart chap and he dropped the term Cross Cutting Concern as we were discussing SharePoint Host Apps (SPHA) and JavaScript.

Problem:  When creating apps for SharePoint 2013 multiple solutions need to address cross cutting concerns.  In the past I deployed a SharePoint library with caching, logging, lazy loading and various other "Cross Cutting Concerns", now for Provider Host Apps (PHA), SPHA and JS embedded within pages and Single Page Apps (SPA) we need frameworks for clients to address common components.

Hypothesis:
Caching for Client Side Code: In JavaScript you can either cache using the client cookie which is small or in HTML 5 based browsers use the JavaScript local store. 
Caching on the Server: All the normal Caching of C# or Azure are available.  Also look at Redis.

Refine your results to a specific site or part of a return result set.

The image below shows how to restrict the results displayed using a "Result Source" at the site collection level to display a subset of data.  You can also refine the results displayed using the search result web parts and reducing the result source set.

The test button is useful to see if your refinement/filtering is working.

The 2 screen below allow me to create new Result Sources.  The result source creates a subset of results that can be consumed by search results web parts.

Tips:

• Search Segmentation allows search content shown to be defined using user attributes such as user locale.
• Managed properties are automatically created for crawled properties in SP2013, this was not the case in SP2010 or FS4SP.

Monitoring SharePoint Public Websites

Overview:  This post is applicable to public website and not just SharePoint, I have used it for SharePoint and feel it is a good product.  The principle will apply to other monitoring products and services.

AlertFox is a SaaS monitoring service.  It allows me to monitor various websites using http posts or complicate macros to perform various steps such as logging into a website using ACS.  This differs from an internal monitoring service such as Solar Winds but it definitely has it's place.  I discuss various monitoring options in this post.

The benefits are:

1. You are notified when the site is down and what the issue is from a web request point of view.
2. You are monitoring externally so you can see what you customers see.
3. You can see if your response time are slowing down.
4. You keep the IIS webservers warmed up (so if you have an app pool recycle).
5. Easy to monitor and you can setup alerts.
6. Complex scenarios can be accounted for in testing so you know the complex parts of your site are working.

SharePoint 2013 on-prem using Windows Live Id via Azure ACS

Overview:  I have a pretty simple requirement to allow users to register on my customers public SharePoint 2013 web sites.  I have setup custom providers and thought ACS was going to make me a hero at my client.  The whole experience is terrible and I can't see why anyone would use the default of LiveId via ACS due to the implementation.

Opinion: I hate the way ACS works with Windows Live Id, it is so bad I can't see a scenario when a client would use it.

Anyway, I have SP2013 SP1 on-prem and I want to hook at ACS allowing customer to register on the site and get elevate permissions on the site.  I'd like them to use multiple 3rd party authentication providers such as Facebook, Windows Live Id, LinkedIn and Google.  In my PoC I decide to simply use Live Id as it is the default on ACS and as both services are Microsoft owned it must be the easiest. 

I worked thru Wictor Wilem's post series and as usual Wictor has provide a great resource.  I had to make minor adjustments to get it to work for me on SP2013 but overall, Wictors series of posts is a good place to start.

The 1st issue I got was when logging in using Windows Live ID, I was continuously redirect back to the /_login/default.aspx page.

After bashing my head trying to figure out what the issue was I realised in Wictor's common issues post in the series, he mentioned the claims mapping/rule needs to be adjusted for Live ID authentication. 

I now was getting an access denied, which at least told me the claim was hooking up.

The next issue was now I was getting the message you are not authorised "Sorry, this site hasn't been shared with you."

Give all authenticated users access to the site as shown below.

Once you login you will notice a horrible looking user that is logged in.   You can assign permissions using the "Friendly Username".

Common public Federation (IdP) Identifcation provides are:

• LiveId (MS - not where you would expect the MS offering to be)
• Google (constantly changing - easy hookup)
• FaceBook
• LinkedIn

Common Enterprise IdP Servers/Services are:

• Microsoft ADFS (best default option for greenfield SP)
• PingFederate (pretty expensive but a comprehensive solution, use if already in place or the advanced features really suit the business at an enterprise level)
• ThinkTextures IdentityServer (Great for customisation, difficult support but for the hardcore tecky type organisation a good option)
• CA-SiteMinder (Good product, used in enterprises and hooks up well to SP.  Has a large set of tools and options).  Update: 19-Nov-2015, seen another large implementation of SiteMinder, it has expensive add-in modules and extremely problematic.  SP agent needs AD groups.
• RSA Federated Identity Manager (No experience)
• Entrust GetAccess (No Experience)
• IBM Tivoli (CAM) (Had a hard time with this a few years back)
• ComponentSpace (Good for .NET customisations, not a large Federation service Server)

PowerShell to Create and Remove Promoted Search Results in SharePoint 2013

Overview: I want to manage promoted results programatically.  PowerShell is a good candidate for automating the creation of "Promoted Results" previously/also known as "Search Best Bets".

In this post I provide PowerShell to create promoted results at the site collection.  The image below shows that my search has picked up 2 pages in my site collection.  I want to display a promoted result when a user types in certain terms in y case the search term is "Messi".  The picture bellows explains what I'm achieving through PS using promoted results.

To manually create Promoted Results:

1. On the Site Collection, go Site Settings > Search Query Rules
2. On the page select "All Sources" for the qu "For what context do you want to configure rules?"
3. And select "Promoted Results Contains", you can add Promoted Results/Best Bets thru the UI at this point.

Or Open PromoteResults.ps1 and edit the Powershell to create the promoted results for you, comment out the DeletePromoteResults, as it is used to roll out the changes.

Run PromoteReults.ps1. 

Search for the term "Messi" and you will see the promoted result.
