Hi Bernardo,
not that I'm aware of.
The IdP Forge component wasn't tested (yet) with autenticacao.gov.pt.
Nevertheless, you need to follow a specific set of steps. Have a look at this documentation (pages 56 to 96). It seems that AMA has added a couple of specific SAML attributes that the IdP Forge component doesn't have.
I would definitely try first using a Web Portal and then if you can make it work pass to the Mobile channel.
Good Luck!
