Description Amit Shah 2014-01-30 06:45:32 UTC
Description of problem:

After upgrading to offlineimap-6.5.5-1.fc20.noarch, kerberos login fails:

GSSAPI authentication failed: AUTHENTICATE command error: BAD ['AUTHENTICATE aborted']. Data: MCGK2 AUTHENTICATE GSSAPI

downgrading to the previous offlineimap makes this work fine.

Comment 1 Amit Shah 2014-01-30 10:03:23 UTC
Version that works alright is offlineimap-

Comment 2 John W. Lamb 2014-12-01 15:11:47 UTC
I have been able to reproduce this; specifically this happens when using SSL + Kerberos with max_connections > 1 - with just 1 connection I can't reliably reproduce the bug.

Comment 4 Matthias Runge 2015-04-14 21:10:05 UTC
this is still valid with offlineimap-6.5.6-2.fc22.noarch

Comment 5 Paul W. Frields 2015-04-14 21:45:09 UTC
Moved version accordingly.  Dodji, are you going to attempt to fix this, please?

Comment 6 Matthias Runge 2015-04-15 06:05:18 UTC
when logged into kerberos AND reducing max_connections = 1 , those issues are gone.

Increasing max connections or logging out of kerberos brings them back.

Obviously, downgrading doesn't work for f22.

Comment 7 Fedora End Of Life 2016-07-19 10:56:52 UTC
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
