I already modify the permission of ESS user, the form shows like what the user who has PIM Access seen. I found the following line
/* TODO: This seems to give view permission to ESS users to admin module */
It will appears like a PIM but they can access only their own profile. and that's what i want to do.
But i got this error
Undefined variable: extractorForm
Encountered the problem in /../../../../../../../CentralController.php Line 1056
Can help me to continue my aiming of modification of ESS.
