Authentication to AD failed using SASL DIGEST-MD5

I am trying to use ldapsearch to access AD. When I use a simple bind such as

ldapsearch -x -D "cn=My Name,cn=Users,dc=mydomain,dc=com" -w mypassword

everything works OK and I get the results that I expect. However, when I

try to use SASL DIGEST-MD5 authentication, such as

ldapsearch -Y DIGEST-MD5 -D "cn=My Name,cn=Users,dc=mydomain,dc=com"

then I always get an authentication error

ldap_sasl_interactive_bind_s: Invalid credentials (49)

additional info: 8009030C: LdapErr: DSID-0C09043E, comment:

AcceptSecurityContext error, data 0, vece

Any ideas what is going wrong?

Thanks in advance.
