[Bug 1342842] [NEW] winbind crashed when "getent passwd" is called

[Paul Ortman]

Public bug reported:

I have samba configured as a member server in a AD.  `wbinfo -u` and
`wbinfo -p` accurately report all the domain users.  `getent passwd`
shows just one domain user and then all the local users.  winbindd
crashes at that point.

smb.conf:

[global]
   workgroup = MERCHANTS
   realm = MERCHANTS.LOCAL
   netbios name = x1
   server string = %h server (Samba, Ubuntu)
   dns proxy = no
   log level = 0 auth:3 winbind:3
   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog = 0
   panic action = /usr/share/samba/panic-action %d
   security = ADS
   #password server = msb-dcdns.merchants.local
   kerberos method = secrets and keytab
   encrypt passwords = true
   client signing = mandatory
   server signing = mandatory
