A couple of important notices in regards to the recently released vCenter 5.1 U1. Take note before starting any upgrades.
- There has been a rather frustrating bug that has been discovered with vCenter 5.1 U1 when using Active Directory logins for administration. If you use a separate administrator account from your daily user account, you may be unable to login to the vCenter web or desktop clients if your user account is a member of more 19 or more Active Directory groups. (Detailed in VMware KB 2050941)
- No version of VMware (Horizon) View has yet been certified with 5.1 U1. Currently only View 5.1 and 5.2 are certified with 5.1 pre-U1.
Update: In the time I looked at the compatibility matrix, wrote this up and posted it, and just a few minutes ago when I was on the matrix again, it appears U1 is now listed as supported. Enjoy!
