If you use Office 365 and DirSync, a user’s primary email address can end up being username@domain.onmicrosoft.com if not setup correctly. To identify all users setup this way, connect to Office 365 powershell and run this command:
Get-mailbox -ResultSize unlimited | Select-Object primarysmtpaddress | ? {$_ -clike “*onmicrosoft*”}
The Digicert cert utility for Windows make the process so much easier:
To generate the CSR:

To install the Cert:

For LDAPS on a domain controller, I did not have to import the cert file into the AD DS personal store.
This post continues my series on the differences between these three manufacturers and how they implement L2 and L3 VLANs.
Scenario 1: Create a Layer 2 VLAN
Cisco:
vlan 10
HP:
vlan 10
Dell:
vlan database
vlan 10
Scenario 2: Create a Layer 3 VLAN (that’s routable)
Cisco:
interface vlan 10
ip address 192.168.1.1 255.255.255.0
HP:
vlan 10
ip address 192.168.1.1 255.255.255.0
Dell:
interface vlan 10
ip address 192.168.1.1 255.255.255.0
routing
The biggest difference between all three manufacturers is that HP does not implement a separate VLAN interface for L3 configuration. Cisco and Dell both require you to go into interface vlan mode before configuring L3 information (IP addressing). Dell also requires the routing keyword to actually route that VLAN.
**All three manufacturers do require you to input the command IP Routing if you want the switch to route packets**
So what is this all about? Technology is one of my passions, and since I work with technology, I come across new and interesting tech every day. I’ll post on here some of my experiences, which includes enterprise hardware/software, consumer hardware/software, project implementations, feature requests, and various other things that I find post worthy.
Let me know what you think, and enjoy!
