[TYPO3] configuring the admin panel for a backend user

[Christian Hensel]

hi list,

i want to configure the FE Admin Panel for a BackendUserGroup.
Im currently searching for a way to fix the simulateUserGroup right from the 
beginning to one certain uid and thougt of:
admPanel {
  enable.edit = 1
  hide = 0
  enable.preview = 1
  preview_simulateUserGroup = 4
  module.preview.preview_simulateUserGroup = 4
#this is the important line above
  enable.cache = 0
  enable.publish = 0
  enable.tsdebug = 1
  enable.info = 1
}

But this did not worked, as if expected. Any other hint how i could 
preconfigure this for a backend user or group`?
TSFE_ADMIN_PANEL%5Bpreview_simulateUserGroup%5D=4

greetings
Christian Hensel
