1. have to store plaintext passwords in ldap directory.
2. ACL on ldap directory must be configured for open access to
userPassword field for read, not only for auth.
3. cyrus imapd must use saslauthd for authentication.
4. saslauthd must have access to users passwords in ldap and must have
configured ldapdb_mech option.
For details see cyrus-sasl2 documentation -- options.html.
