[Samba] samba (3.0.20) doesn't use TLS for LDAP referrals

Hello,
Now I'm trying to move the LDAP backend from the master OpenLDAP
server to a slave one. The ACL rules for all directories requires
a "ssf = 112" (Security Strength Factor) just to be sure that all
connections are properly encrypted. Also the slave directory has a
referral directive pointing the master directory.
Samba works perfectly with the slave directory except when a write
operation is done, then it gets a referral and this time the modification
is tried with the master but with an unencrypted connection.
I can see _four_ unencrypted tries to the master directory server and
a network trace confirms that samba doesn't use TLS with referrals.
first contact with the slave directory:
Sep 29 18:25:43 slave slapd[30977]: <= check a_authz.sai_ssf: ACL 112 > OP 168
fwe seconds later the referral is followed:
Sep 29 18:25:45 master slapd[6738]: <= check a_authz.sai_ssf: ACL 112 > OP 0
is it a bug in samba? or in the OpenLDAP libraries?
Thank you.
