It seems the Beta 8 gateway has a problem with Yahoo username with periods in them (single periods are valid in Yahoo! usernames). Anyone else seen this?
Use Spark or any other XMPP client to log into a Openfire server running the Beta 8 gateway component
Log into the Yahoo service using the username “test.xmppgw” with the password “wildfire”
You will get an error back from the transport:
“Your registration was denied because the username you provided was not valid for the service”
