Red Hat Bugzilla – Bug 212816
mutt fails to authenticate with latest cyrus-sasl
Last modified: 2014-07-29 06:51:44 EDT
When trying to get pop mail with mutt (220.127.116.11-3), sasl authentication will
always fail. This is due to a change in cyrus-sasl version 2.1.22, as described
in mutt bug 2478. (Open URL, log in with user:guest pass:guest to see it.)
The patch the mutt devs have applied to fix this is here (CVS HEAD):
This patch to pop_auth.c is hard to backport however, because of another patch
in the mutt src rpm: mutt-1.4-sasl2.patch. But the part that matters is:
-sasl_decode64 (inbuf, strlen (inbuf), buf, LONG_STRING-1, &len) != SASL_OK)
+sasl_decode64 (inbuf+2, strlen (inbuf+2), buf, LONG_STRING-1, &len) != SASL_OK)
I removed the leading spaces and && here to fit it on one line.
I think the other changes in their fix are to "enable SASL plaintext:
$foo_authenticators [as] a more general solution" as their cvs log says.
Since the equivalent line in 1.4 is also altered by the sasl2 patch I'm not sure
how to propose a patch, in fact I tested this fix by editing the sasl2 patch.
Anyway, add '+2' to both 'inbuf's in that line and sasl auth will work again.
Fixed in mutt-18.104.22.168-4.fc6. Thanks.
mutt-22.214.171.124-4.fc6 has been pushed for fc6, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
