ldapsearch against win2003 AD failed with dotted username.

# ldapsearch -x -b "cn=Users,dc=domain,dc=info" -D
"cn=testuser,cn=Users,dc=domain,dc=info" -W -h win2003pdc -p 389
__works fine__

# ldapsearch -x -b "cn=Users,dc=domain,dc=info" -D
"cn=test.user,cn=Users,dc=domain,dc=info" -W -h win2003pdc -p 389
__generate error__ :
ldap_bind: Invalid credentials
additional info: 80090308: LdapErr: DSID-0C09030F, comment:
AcceptSecurityContext error, data 525, vece

Both users are exist in AD and have normal passwords. Is there a hardcoded
filter for dot in usernames?
