Package: dovecot-imapd
Version: 1:1.2.15-7
Severity: normal
This seems to be a regression from lenny, and was found to be the
source of the IMP4 web mail system becoming essentially unusable,
since the 5s delay hits just about any operation in the web mail system.
In this case dovecot imapd announces GSSAPI and PLAIN athentication
methods to
an imap client using the libc-client library. The libc-client code
first starts using GSSAPI without first checking for a a Kerberos
ticket cache, and when later the ticket cache is found not to exist,
aborts the authentication and tries with PLAIN instead. At this point
squeeze imapd delays for 5s. This does not happen when using the same
client against a lenny imapd.
The was reported upstream and fixed in
<http://hg.dovecot.org/dovecot-1.2/rev/e7721f67688a>.
Upstream states this problem is not present in dovecot 2.0, so this
report is for the (slim) possibility of having a stable update.
Thanks
Arne
