Please help: Rhel5.6 and ldap+sasl

On Debian i set my ldap server,using tls and all works ok.
On Redhat i have set my ldap server,using tls ok...but
when i try to use ldapsearch without -x and with rootpw(created with slappasswd) it ask for sasl password!
The question is: is possible to disable sasl?
Thanks

Which LDAP server are you using on Redhat - the Red Hat Directory Server or the 389 directory server?

Openldap with tls(ldaps).
