[Bug 1554720] [NEW] Winbind maxing out CPU when AD user logs in with expired password

[Mike]

Public bug reported:

Hi,

My systems are Ubuntu 14.04.3 LTS with samba/winbind 2:4.1.6+dfsg-
1ubuntu2.14.04.11

I am experiencing issues as described in this Samba bug:
https://bugzilla.samba.org/show_bug.cgi?id=11038 which is entitled
'Logging with an account which has the "User must change password on
next logon" flag cause winbindd to use 100% cpu and stop answering
request'.

Jeremy Allison marked this as a blocker bug with the comment "We must
not ship another Samba release with this bug unfixed".

The bug appears to have been fixed in Samba 4.2 and 4.3 releases, but
not in 4.1. Is there any plan to port this bug fix into releases
available on Ubuntu 14.04 LTS?

Mike
