Thank you for responce but unfortunately I didn't catch what you mean
I have created AD group "test_group". Added my account as a member of the group "test_group"
I have not installed vcenter yet. I am trying to install it but with no luck/
What do you mean by "SSO users accout"?
SSO process "ssotomcat" is runnig through "wrapper" process which is started by SYSTEM account.
Could you please point me directly where I can find the SSO users acount
Thank you
