Maybe this bug could deserve more information from the original bug submitter but I didn't want to forget about forwarding it.
So, one of our users reported the following:
I get segfault while trying to get a list of share.
192.168.0.3 is my local IP.
ea@debian:~$ smbclient -L 192.168.0.3
Enter ea's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.1]
Server requested LANMAN password (share-level security) but 'client lanman auth' is disabled
ea@debian:~# dmesg | tail -1
[17713.467193] smbclient: segfault at 4000001ad ip 00007f5d786d81b4 sp 00007fffb6a7f110 error 4 in libtalloc.so.2.0.1[7f5d786d6000+9000]
The segault disappears when the user enables "client lanman auth" in smb.conf
This is very likely a duplicate. Please re-open this bug if
does not solve this for you.
