Syncing MFA Office Phone information with extensions from AD to Azure AD / Office 365


In anticipation of rolling out MFA to our Office 365 users I was looking at the setup page (aka.ms/MFASetup) and I noticed that the Office Phone area was showing some of my information, but not the correct information.

Let's track that down, figure out how it works, talk about the Standards, and push a correctly formatted Office Phone to all the users

Setting up email for Brand Protection domains


So at my dayjob we have a pretty good amount of domain names we've registered for brand protection or typo domains. 3 domains we send or receive emails on, and 23 domains that just forward to a URL on our main domain. Our customer care got word of someone sending scam emails on one of the brand protection domains that should never be sending emails.

Let's explore how I setup our parked domains to report spoofers to me and help other mail servers know they shouldn't trust these emails pretending to be us.

Updating iDRAC SSL Certs through Powershell


One of the things I'm working on at work right now is updating all our iDRACs after Meltdown/Spectre. We had never had the SSL set up, we had just always clicked through the security warning. I got tired of this and decided to setup proper SSL from our enterprise CA,

At first I went to do a manual signing for a multi-year period with a wildcard issued from my enterprise CA, but I decided that automating it with PowerShell would be better, since it would be more dynamic, and scale to more servers.

In this post, I will be talking about setting

  1. generating a Certificate Signing Request (CSR) from the iDRAC,
  2. sign it with an enterprise CA, 
  3. uploads the signed cert to the iDRAC, and  
  4. reloads the iDRAC to apply the new cert
