Hi Andrea,

this is not configurable by the SAML admin panel right now (maybe I will include that functionality in a future release).

but you can custommize the SAML Extension. If you go to the Magento root path and edit the file:

code/community/Onelogin/SAML/Helper/Data.php

at the bottom of the processSSO method there are 2 lines that redefines the $urlToGo var:

$urlToGo = Mage::getUrl('customer/address/edit/id/'.$customAddress->getId());

and

$urlToGo = Mage::getUrl('customer/address/new');

simply comment them, and the user will be redirected to the default page of the site, or to the RelayState URL if there is any.

also if you want to redirect to a specific account you can specify it....

I published the 1.1.5 version that supports what you were asking for.
