how to NOT use SASL

Hi list,

Now this is something I don't understand. TSL shouldn't require the use of sasl, logically speaking, yet why am I getting this output?

frvdamme@osc1:~$ ldapsearch -w dd -D 'cn=admin,dc=otec,dc=vub,dc=ac,dc=be' '(cn=admin)' -H ldap://localhost -x ldap_bind: Invalid credentials (49) frvdamme@osc1:~$ ldapsearch -w dd -D 'cn=admin,dc=otec,dc=vub,dc=ac,dc=be' '(cn=admin)' -x -H ldap://osc1 -x ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)

So the only difference is how I specify the hostname and ldapsearch chooses to use sasl, even though I'm specifying -x. Why??
