Kerberos shared secret key creation

There are 3 things that I don’t fully understand about kerberos.

  1. Let’s say that we are adding new server to an AD Domain. KDC creates a shared secret for this server and how is this key send securly to the server?

  2. There is a user who is a member of AD domain. User have his secret key (password) and he is changing it – how is it securly pass to KDC to update it’s database?

  3. Since each DC can (or maybe must) have KDC, is the KDC database replicated between each DC? If yes, how is this secured?

Proving NP hardness about graph creation problem with triangle number

I have graph creation problem.

Given a set of nodes of graph, and node constraints such as given every node’s number of neighbors (degree). I am also provided with the total number of triangles in the graph. Given the above constraints ($ n+1$ ), I have to generate a graph that satisfies all the constraints.

I know that given nodes’ degrees, it is possible to construct using Havel–Hakimi algorithm a graph satisfying node degrees. But I am not sure how to fulfill the total triangle count constraint and if it makes the problem NP-hard.

SP 2013 – Automate item creation in list

I have a Sharepoint list (with a Nintex workflow) which objective is to give a tracking to canceled orders from our products.

Each product is known as a ‘Style’, each Style can have multiple orders.

The reason they would cancel orders varies. Every time they canceled an order they will go to the SP and add it via an infopath form.

For example, there are 20 orders for Style 1 and all those orders were canceled and made into 1 order. Right know, the users would have to go and add 20 items (one for each canceled order) with practically the same information since the 20 orders were joined into 1.

I wish to simplify that, but for data integrity we cant allow the users to write 20 orders in one go, like “Order01, Order02… Order20” -> “NewOrder01”.

An idea I had was to have a another list, where the users will be able to write orders separated by a comma in a field. Then the flow will go through each order in that field and create as many items as there are in our main list, all with the same data except of course with a different canceled order.

Thing is, I am new to sharepoint and I dont know how to this. I can only use nintex.

Disable Teams Site Creation

My mind is blown here. A regular use just created a Team from within MS Teams client application. This then created an O365 Group with inbox. It also created a new SharePoint site collection and locked out the administrators.

This is a governance nightmare and circumvents our security model, our information architecture, our navigation and branding. What is Microsoft thinking?!

O365 groups and SharePoint site collections should only be created by Admins (EVER). How do you disable the creation of ‘Teams’ and resulting site collections from the MS Teams client?

Content Creation / Data Entry


I'm looking for someone to be able to do some data entry and create a entire list of businesses for my site.

Will require some knowledge on how to use a backend website to enter data ( ex, using wordpress or drupal ). Basically using a web form and adding content.

Please PM me your estimated hourly rate or bulk pricing . Example 1000 entries for X amount.

More details will be provided to serious inquiries.

Thank you

Remote Desktop 10.2.3 Database Creation Error; 10.2.1 runs fine; 10.2.2 crashes: how to find actual cause(s)?

What would be good steps to find the cause of the below errors?

I get this error when running Microsoft Remote Desktop 10.2.3 or higher on MacOS High Sierra: enter image description here

Database Creation Error  "An error occurred during persistent store migration.  [Domain: NSCocoaErrorDomain, Code: 134110]" 

I am stuck at 10.2.1 now (which cannot add user accounts and will eventually stop working), want to use the newer version, but cannot use intermediate 10.2.2 as it crashes with the below information that I repeatedly submitted with the “Problem Report for Microsoft Desktop”.

Manually migrating all the machine and user entries is really cumbersome: there are hundreds of them.

Information that might help:

  • where is the information on entries and users stored?
  • what format is that information stored?
  • are the tools for converting that information between various versions?
  • where are crash reports stored?

Crash report on 10.2.1:
