Access SQL Server database from Lotus Notes using lsxlc

I am making a new app in Lotus Notes, it requires to access a MS SQL Server for accessing some data and past them in a Lotus Notes document.
I want to use lsxlc for this, but I can not make the logon to work, I get a 12325 error "Logon failed"
I think that the problem is in the name of the server or user name.    I have tried many options but with no sucess

Something wrong here?    Thanks

Uselsx "*lsxlc"
