I'm using Pidgin as shipped with Red Hat 5.5. Pidgin identifies as "Pidgin 2.6.6-2.el5_4".
When I try to log into our university's XMPP server, Pidgin fails to connect claiming, "503: Service Unavailable." Co-workers using identical installs on the same machine are able to log in without problem. I've tried reentering my password repeatedly. I'm confident it's the correct password. I've tried wiping out my ~/.purple directory and starting fresh. I've tried stracing Pidgin to see if there were other files in my home directory that it might be reading and receiving bad information from; I didn't find any. I do not have a ~/.pidgin or ~/.gaim. I nosed around in gconf-editor for a bit and didn't find anything that seemed relevant to Pidgin. Pidgin otherwise works fine; I've been using it to talk to AIM, YIM, and MSN for years. Enabling debugging, I notice the following interesting exchange between Pidgin and the server. This is immediately after successfully negotiating and enabling TLS, as is required by our server.

Comparing to a co-worker who is able to log in with an identical install, I see this, which looks like I would expect: certificate: Successfully verified certificate for wisc.edu jabber: Sending (ssl) (dele...@wisc.edu/Work): <stream:stream to='wisc.edu' xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' version='1.0'> jabber: Recv (ssl)(166): <?xml version='1.0'?><stream:stream xmlns='jabber:client' xmlns:stream='http://etherx.jabber.org/streams' id='3897413721' from='wisc.edu' version='1.0' xml:lang='en'> jabber: Recv (ssl)(129): <stream:features><mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><mechanism>PLAIN</mechanism></mechanisms></stream:features> sasl: Mechs found: PLAIN jabber: Sending (ssl) (dele...@wisc.edu/Work): <auth xmlns='urn:ietf:params:xml:ns:xmpp-sasl' mechanism='PLAIN' xmlns:ga='http://www.google.com/talk/protocol/auth' ga:client-uses-full-bind-result='true'>password removed</auth> To my relatively clueless eyes, it looks like the remote server is saying, "Please use PLAIN." When my coworker runs Pidgin, it replies with the password. When I run Pidgin, it replies with "I don't understand PLAIN, what other options are there?" It was suggested that the package cyrus-sasl-plain might be missing, but RPM reports that cyrus-sasl-plain-2.1.22-5.el5_4.3 is installed. And even if it was, it doesn't explain why a co-worker using the same machine and same binary didn't encounter this problem. I've been using Pidgin for years, back since it was GAIM. I previously used it with XMPP servers, but not recently. It's entirely possible that I have some old configuration that is causing problems, but I have no idea where I might find it to remove or fix. Can anyone offer suggestions for fixing this? I have longer logs, both from me and the co-worker who is successfully using Pidgin to talk to our XMPP server. If there are additional subsets that would be useful, please let me know. -- Alan De Smet Condor Project Research ades...@cs.wisc.edu http://www.cs.wisc.edu/condor/ _______________________________________________ Support@pidgin.im mailing list Want to unsubscribe?
