I have this error when I try to configure ZDesktop with my Yahoo:
Service error. Please check your server settings; verify your email address, password or client access permissions (if required).

I really don't know what is wrong, this is the zdesktop.out file content:
0 INFO [main] log - Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4jLog
563 INFO [main] log - jetty-6.1.5
703 INFO [main] log - No Transaction manager found - if your webapp requires one, please configure one.
Zimbra server process is running as uid=-1 euid=-1 gid=-1 egid=-1

The only thing that I can think in it right now is that my connection is going through a proxy (Microsoft ISA), is there any specific configurations in this ???!

Thanks in advance
