Package: winbind
Version: 2:3.2.5-4lenny9
Severity: important

I added my linux server to a windows AD using winbind / samba. Everything worked just fine. After changing the OS to Debian lenny x64 I get a "segmentation fault" when trying to change user passwords. I am using the exact same configuration, on my 32 bit Server everything works. Any ideas?

debian:~# passwd <user>
sgmentation fault

debian# tail /var/log/syslog:
kernel: [689689.005934] passwd[11209]: segfault at 0 ip b7b84418 sp bfc37fc0 error 4 in pam_winbind.so[b7b7e000+b000]
