POSTFIX - SASL - LDAP -JAMM

Hi list,
i'm trying to set up SASL work with Postfix:
Jamm-(LDAP)-Postfix already works
But i can't have POSTFIX to work with SASL, smtpd crashes.

my /usr/lib/sasl2/smtpd.conf :
############
pwcheck_method: saslauthd
mech_list: plain login
############

I run saslauthd with a command like:
/usr/local/sbin/saslauthd -t 30 -c -a ldap -O 
/opt/local/etc/saslauthd.conf -m /opt/local/var/state -V

With that, sasl auth daemon run with ldap as auth mechanism, with 
config file /opt/local/etc/saslauthd.conf:
############
ldap_scope: sub
ldap_auth_method: bind
ldap_debug 1
mechanisms="ldap"
ldap_servers: ldap://127.0.0.1/
ldap_bind_dn: cn=Manager,dc=mydomain,dc=com
ldap_bind_pw: clear_text_jamm_admin_password
ldap_search_base: o=myhosting,dc=mydomain,dc=com
ldap_timeout: 10
ldap_filter: (&(objectClass=JammMailAccount)(mail=%u))
ldap_password_attr: userPassword
ldap_verbose: on
############

When i run testsaslauthd:
testsaslauthd -u [email protected] -p cleartextpassword
0: NO "authentication failed"
#### auth fails...

i just get
and in syslog, i get:
Oct 26 15:31:30 mail saslauthd[15368]: do_auth         : auth failure: 
[[email protected]] [service=imap] [realm=] [mech=ldap] 
[reason=Unknown]

So, what could be the problem? i tried my filter in an ldap browser, it 
works...
Perhaps this doesn't work because Jamm porperty called userPassword is 
an MD5 hash ?

did someone succeeded in authenticating SASL against Jamm schema ??

thx to read me and perhaps correct me
Tristan
