Title:
  segfault in samba with Active Directory users

Status in “samba” package in Ubuntu:
  Expired

Bug description:
  I'm using Samba (3.6.3-2ubuntu2.3) in Ubuntu 12.04.1 LTS (fresh install).
  The server has joinded succesfully the Active Directory Domain.

  Samba.conf global,

  [global]
     workgroup = XXX
     server string = %h server
     dns proxy = no
     log level = 1
     log file = /var/log/samba/log.%m
     max log size = 1000
     syslog = 0
     panic action = /usr/share/samba/panic-action %d

     security = ADS
     realm = XXX.LOCAL
     password server = svr-dom.xxx.local
     winbind separator = +
     winbind cache time = 300
     winbind use default domain = yes
     winbind refresh tickets = yes
     client use spnego = yes
     winbind use default domain = yes
     domain master = no
     local master = no
     preferred master = no
     winbind enum groups = yes
     winbind enum users = yes
     winbind use default domain = no
     idmap uid = 10000-20000
     idmap gid = 10000-20000
     template shell = /bin/false
     encrypt passwords = true
     passdb backend = tdbsam
     obey pam restrictions = yes
     unix password sync = yes
     passwd program = /usr/bin/passwd %u
     passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
     pam password change = yes
     client lanman auth = yes

  A sample share:

  [backup]
     comment = backup
     read only = no
     path = /home/backup
     guest ok = no
     browseable = yes
     create mask = 0600
     directory mask = 0700
     valid users = XXX+administrateur,besr

  Samba shares with Active Directory users works fine, but i can see in
  the log files  segfault :

  http://paste.ubuntu.com/1226116/

  I don't have these errors with  linux "local" user. For example with
  user "besr" it's ok.

  Let me know if i can more detailed test for this issue. I have the
  feeling taht this segfault cause perfomance issue, but i'm not sure
  yet. Still investigating.
