I recently installed Jitsi and everything has worked great except for when I tried to log into ICQ. I had the ICQ client installed and could test that I was entering the password (11 chars long) correctly, but the Jitsi client kept telling me the password was wrong. I went looking on the internet and found this:
Interestingly enough, that post from 2006(!) suggests that password truncation has been the practice for passwords longer than 8 characters. I then went on to test with a 9-char password (failed), an 8-char password (succeeded), and then a 7-char password (again, success). What this suggests to me is that Jitsi still truncates the password while the official client/protocol has now extended their password length (password change page says 6-16 symbols required, which means they probably doubled the limit).
While I'm currently using an 8 char password I'd rather be able to use my 11 char one.... If I can have someone help me with this I am a willing guinea pig
