CPE's option "ACS Username/Password": Does it exist?

[Sergio Fernández]

Hi,

This is a simple basic question but I haven't found the configuration 
file to change the ACS User/Pass login for the CPE's. Maybe, as I 
expect, this doesn't exist, as in my Tenda W300D I need to configure the 
ACS URL, the ACS User Name and the ACS Password. But it doesn't matter 
what do I write in User/Pass, it logs in successfully to GenieACS.

Thank you.
