invalid address used for login (no matter what coin)

[gjnardoni]

Hello.
I'm trying to build a mining pool for Bitcoal (among other from forknote).
Pools build and start perfect but when I try to mine I receive the "invalid address used for login".
I also try for Quazarcoin and same happens

I think it is a cryptonote-util but I don't know
Could you please lend me a hand?
