VMware: Integrating OpenLDAP into SSO/PSC over LDAPS

Image
Summary:
Quite simply was trying to get an OpenLDAP identity source added to SSO/PSC.  Would work fine using non-secure LDAP, but seemed to have issues when attempting to utilize secure LDAPS.  Simple error, nondescript basically describing that it failed.

Heres what happened in my case:

I had two server URL's defined for my target LDAP servers.Since I had the "Protect LDAP communications..." box checked, the next step requires me to either upload the target system's certs and their authoritative chains (think Root Certificate Authority (CA) and Intermediate CA's)If you can, uploading the needed certs would save some time, otherwise you can continue w/ my outlined steps below assuming the spyglass icon works in the same fashion for you.The cert upload screen has a little spyglass icon that'll pull it down for you, but in my case it would only pull the primary server's cert and associated CA certs.  It would not pull the secondary for some reason.If I went …

Misc: Fire TV Stick 2 Screen Cut Off, no display adjustment option

Summary:
Long story short, Fire TV Stick (2nd Generation) doesn't allow you to calibrate the screen, software wise, forcing you to use your TV settings (if available) to fit the screens content within it's borders.  Super annoying for some apps, but you can fix this dumb issue as I was able to.

If your TV allows you to adjust its settings, then you'd be fine as well, but the Vizio I have, has no such setting.

Solution:
Get the Amazon Fire TV instead.  It's only slightly more expensive, but doesn't suffer the problems the Fire Stick does.



Workaround:
First you have to enable ADB debugging (step 1 here) on your fire stick.Next you'll need the ADB provided w/ Android Studio, or you can install w/ brew on the Mac.I prefer brew cause it's easier, keep following steps described by Amazon page if you are using Windows.Open Terminalbrew cask install android-platform-toolsNext find the IP address of your FirestickSettings --> Device --> About --> NetworkSteps a…

VMware: vSphere Scheduled Tasks w/ PowerCLI (not to be confused w/ Windows scheduled tasks)

Image
Summary:
Question was posted in the communities on how to find scheduled tasks configured against a VM.  I remembered doing it long ago, but I never posted about it.  Also found it weirdly hard to find via Google, so I'm posting here for my own reference or anyone else needing it for that matter.

VMware: Migrating Management(Mgmt) vmk to DVS/VDS fails when moving both vmnic and vmk at the same time.

Image
Summary:
Quite simple, had a script to move physical nics to DVS/VDS w/ management vmk at the same time.  Typically this works w/o issue, but for some reason kept failing.  The answer was dead simple...

Resolution/Workaround:
Spanning Tree Enabled?Enable portfast on the switch ports.OrSpanning Tree not available?Move one physical link at a time (assuming more than one physical link available)Wait for uplink on DVS to come online, then move management/mgmt vmkExplanation:
Basically, the switch ports that the ESXi servers were uplinked to did not have 'portfast' (physical switchside config) enabled.  Without 'portfast', when moving a physical nic from a standard vSwitch (or vice versa), there is a negotiation downtime the host incurs as the switch/host essentially renegotiates the connectivity.  It's a short window (5-10 sec) that the port goes 'offline', but it's enough for the migration of vmk and physical nics at the same time to fail.

Example PowerCLI Sn…
