we've built a test box for zimbra 5 to try things out before migrating from 4.5, and are especially keen to get messaging working so that we can stop staff using 3rd party servers.
so, we have two email addresses set up, email@example.com and firstname.lastname@example.org
my configuration is as follows:
Screen name: test1
Local alias: blahblah
Force old (port 5223) SSL: off
Allow plaintext auth over unencrypted streams: ON
Connect port: 5222
Connect Server: zimbra5test.example.com
Proxy type: No Proxy
we cannot get pidgin (aka gaim) to login to the jabber server, I have tried many different things - I can "tcpdump" and see the attempts to connect on port 5222 if I do not enable ssl; I can also make pidgin attempt to connect to 5223 too, but it always says simply "Not Authorised".
I know my pidgin installation is working as I'm logged in to googletalk's xmpp service.
BTW, when logged in to webmail, we can send messages between accounts but the messages do not arrive!
