pam is not a valid sasl_passwd_check in sasl v2.  You need to use
sasl_passwd_check: saslauthd.  You also need to start 'saslauthd -a

Alternatively, you can try to use ldap support in saslauthd.  You will
need to download the latest cyrus-sasl from
http://asg.web.cmu.edu/cyrus/download/.  The saslauthd ldap docs were
omitted from this release, but you can find them in CVS,
