This is little off-topic, but I have the same problem with Centos 5 and cyrus-sasl-2.1.22-4.

What I see with strace is

open("/etc/shadow", O_RDONLY) = 8
fcntl(8, F_GETFD) = 0
fcntl(8, F_SETFD, FD_CLOEXEC) = 0
fstat(8, {st_mode=S_IFREG|0400, st_size=753, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2abde20b7000
read(8, "root:!*:35456:0:99999:7:::\nbin:*"..., 4096) = 753
close(8) = 0
munmap(0x2abde20b7000, 4096) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---

SASL is started as following:

$saslauthd -a shadow -c -O /etc/saslauthd.conf -n 1

On the other hand, my SASL is working fine with LDAP.
