I cannot auth against SASL

Hi!

i am trying to authenticate binding the DN below and it works nicely.

dn: uid=grios,ou=people,dc=ufv,dc=br uid: grios objectclass: organizationalrole objectclass: posixaccount cn: Gustavo Rios uidnumber: 2000 gidnumber: 2000 homedirectory: /home/grios userpassword: {SSHA}dWhcPjgDn4EGb/FwGMYbxx7fIqAuXCN7 loginshell: /bin/sh gecos: Gustavo V G C Rios,,,

But if i change userpassword attribute to {SASL}grios@UFV.BR it does not work when i bind the same DN above. Does anybody have an ideia about my mistaken ?

Thanks in advance.
