Package: winbind
Version: 1:3.0.28a-3
Severity: critical
Justification: breaks unrelated software
We are using winbind to authenticate users to the system for various
services. The winbind daemon seems to crash many times a day. At the
moment I have a cron job that restarts winbind and samba every time as
crash has been detected to minimise the impact on the system.
This happens on two separate servers that we run winbind on.
They are both located in different networks in different Active Directory
environments.
I'll just report on one of the hosts that is more active and suffers from the
crashes more frequently.
Output from 'testparm -s /etc/samba/smb.conf' is as follows:
Load smb config files from /etc/samba/smb.conf

The program is running. Quit anyway (and detach it)? (y or n)

The above seems to suggest something going wrong with LDAP?
I have the latest libraries for LDAP in the testing distribution installed.
Output from 'dpkg --list | grep ldap' is:
ii ldap-utils 2.4.7-6.3 OpenLDAP
utilities
ii libldap-2.4-2 2.4.7-6.3 OpenLDAP
libraries
