IMAP Connection Dies on Fedora 13

[Joel J . Adamson]

Hello,

I have the following setup in .emacs-custom.el:

 '(gnus-select-method (quote (nnimap "imap.unc.edu" (nnimap-stream ssl))))
 '(gnus-secondary-select-methods (quote ((nntp "news.gmane.org"))))
 '(mail-user-agent (quote gnus-user-agent))
 '(read-mail-command (quote gnus))
 '(gnus-message-archive-group "INBOX.Sent")

When I try to log in to the IMAP server, I get this in *imap-log* (with
the password obscured here):

41 OK Completed
depth=0 O = *.unc.edu, OU = Domain Control Validated, CN = *.unc.edu
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 O = *.unc.edu, OU = Domain Control Validated, CN = *.unc.edu
verify error:num=27:certificate not trusted
verify return:1
depth=0 O = *.unc.edu, OU = Domain Control Validated, CN = *.unc.edu
verify error:num=21:unable to verify the first certificate

SASL-IR] imap.unc.edu Cyrus IMAP Murder v2.3.14 server ready
42 NOOP
42 OK Completed

I get

Opening nnimap server on imap.unc.edu...failed

in the echo area.

However, when I run the ssl command manually in a shell, and login,
here's what happens:

joel@localhost: ~ > openssl s_client -quiet -ssl2 -connect imap.unc.edu:993
depth=0 O = *.unc.edu, OU = Domain Control Validated, CN = *.unc.edu

Seems like gnus is not following through, not listening or something
else is amiss.

Today's Friday, this worked just fine with the same settings on
Wednesday, but when I came in to my office on Thursday I did an update
that included gnutls.  After that it stopped working.  Everything works
fine on a Fedora 12 machine at home, but I get the same errors on
another Fedora 13 machine.  Also, on the same machine where gnus is
failing, Evolution, mutt and mail-notification have no problems at all.

Gnus v5.13

GNU Emacs 23.2.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.20.1) of 2010-05-13 on

Thanks,

Joel
