Reinstalling Samba in Debian changed the database to tdbsam while my
original smb.conf didn't use tdbsam. Adding the following lines to
smb.conf fixed the problem:

encrypt passwords = true
passdb backend = tdbsam
obey pam restrictions = yes
unix password sync = yes
passwd program = /usr/bin/passwd %u
