SSO is an integral part of providing access rights to your Vcentre server. You can assign permissions to people based on their user account, group memberships and link it with various authentication methods. After installing Vcentre for the first time log onto the Web Client with the username email@example.com and the password you used during the install. The address for the Web Client will be https://Server Name:9443/web-client Though if you selected a different port to 9443 during the installation then use that.
While testing out a Server 2012 install on ESXi 5.5 I noticed that when copying files between it and any other server I would get a PSOD. The main section of the PSOD that got my attention was E1000PollRxRring@vmkernel After a bit of searching around I found that there seems to be a common issue with Server 2012 and Server 2012 R2 using the E1000 NIC. Standard solution seems to be remove your current E1000 NIC from the guest machine and add a NIC running as VMXNET3.
