Description Erik Sørnes 2009-03-01 04:38:29 UTC
First, i run ./configure --prefix=/usr/local/samba-3.3.1 --with-shared-modules=vfs_acl_xattr --with-acl-support && make && make install

Then I run /usr/local/samba-3.3.1/sbin/smbd  -i -d 9 on my x64 - ubuntu 8.10 server.

Then I type in \\10.0.0.102\temp in my explorer-window on my windows2003sp2-client

Imediatly after, smbd segfaults with this:

I have checked with ls that /usr/local/samba-3.3.1/lib/vfs/acl_xattr.so actually exists.

My smb.conf is like this:

[global]

preload modules = /usr/local/samba-3.3.1/lib/vfs/acl_xattr.so
registry shares = no
interfaces = 10.0.0.102
bind interfaces only = yes
workgroup= w2k3dom
realm = W2K3DOM.TEST.PRIV
netbios name = hamster
security = user
encrypt passwords = yes
password server = windows2003-nr1.w2k3dom.test.priv
wins support = no
idmap uid = 10000-20000
idmap gid = 10000-20000
log level = 10

[temp]
	comment = temp
	read only = no
	locking = no
	path = /temp
	guest ok = yes

Cannot repsoduce that in 3.3.4.
Is that still an issue?
