saslauthd is not involved here. For what you want there are at least 2 ways:
1) You can use nss_ldap to map LDAP groups to Unix groups which can then
be used by a group:name ACL. Please note that you may need some way of
group caching for large groups, as those lookups are expensive on the LDAP
side. For it you could use nss_db or the patches I use available here
http://www.invoca.ch/pub/packages/cyrus-imapd/scripts/groupcache/.

2) As you mentioned, pts with it's ldap support should also work (I have
never used it so I can't tell how exactly it works).
