My company uses Gtalk for their chat system, but we use our own email addresses. In Pidgin, I have the option to enter my email address (e.g. email@example.com) with a.b in the username field, and c.com in the domain field. The connect server is talk.google.com. This allows me to connect to Gtalk via Pidgin.
However, Spark/Kraken does not offer the domain field. I tried using firstname.lastname@example.org as the username. I tried c.com\a.b as the username. Neither work. However, when I click the test button in the admin control panel, it says I can connect successfully to the Gtalk server. So I can connect, but I can’t authenticate.
What can I do to get Spark/Kraken to authenticate to Gtalk?
