Hello, Now I am back to my old error I was fighting last year... Alert: Access Denied Error Resolution state: New Source: BOPCCVM003.ad Path: Last modified by: System Last modified time: 4/28/2011 4:27:56 PM Alert description: The RunAs account does not exist on the Unix/Linux Server. the accounts svcunixa and svcunixu have been added as other servers what has changed: Server ESXi Red Hat 5 Active directory authrntication - Built-in for ESX servers (previously it was done through centrify) Investigating... Should I change the Basic Authentication previously used to a Windows Accounts type? Previously from an AD\SVCUNIXA centrify was chnaging it to svcunixa and the basic authentication was using svcunixa the wheel group on the linux server was using svcunixa as well. Now the AD\SVCUNIXA is no more changed as ESX is using AD Authentication !!!!
