[Bug 264982] [NEW] Segfault in Samba

[Geoff King]

Public bug reported:

Binary package hint: samba

Just to clarify my setup.

I have a HP Prolient DL140 G3 with an External MSA60 Disk Storage Array
setup as a file server for my users file areas. I have configured the
disk array as software raid5 with LVM on top of it. There are then
various LVM volumes for each group of users, mounted under /home. Each
user of each group has their home directory located in one of these
mounted volumes.

As my users are connected to a W2k3 domain (W2k8 DCs though) I share
their home directories via samba at the group level. So /home/groupname/
is shared as groupname$. Thus samba is configured so the machine appears
as a AD domain member server.

Here is the backtrace:
