When I login with a user mapped to System_u SELinux user there is no such error messages, But when I login with a user mapped to sysadm_u SELinux user there is a such error message ( some desktop icons are not loaded correctly) As you know you could mapped any linux user with a SELinux user in the following text file /etc/selinux/mls/seusers.
As you know the system_u SELinux user has less than sysadm_u SELinux user in viewpoint of privileges. So could you tell me that How I could overcome to this problem?
