CFLDAP: can't bind to AD as "currently logged on user"

First I used Softerra's LDAP browser to figure out what I need to gain access to our AD.

Specifically I had to use this bind technique:

CFLDAP attempt leaving out username:

<CFLDAP       action="query"       name="results"       start="CN=js9999,OU=XXXXX,OU=Users,OU=xxxxx,DC=XXXXXX,DC=xxx,DC=com" attributes="*"  server="ouradserver.bigcorp.com" 
/> 

RESULT: An error has occured while trying to execute query :[LDAP: error code 1 - 000004DC: LdapErr: DSID-0C0906DD, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1772 ].

Attempt with username and no password.

<CFLDAP       action="query"       name="results"       start="CN=js9999,OU=XXXXX,OU=Users,OU=xxxxx,DC=XXXXXX,DC=xxx,DC=com" attributes="*"  server="ouradserver.bigcorp.com"   username="js9999"
/> 

RESULT: The system has attempted to use an undefined value, which usually indicates a programming error, either in your code or some system code. Null Pointers are another name for undefined values.

It insists on a password, which I do NOT want to provide.

Attempt with "rebind" parameter:

<CFLDAP       action="query"       name="results"       start="CN=js9999,OU=XXXXX,OU=Users,OU=xxxxx,DC=XXXXXX,DC=xxx,DC=com" attributes="*"  server="ouradserver.bigcorp.com"   rebind="yes"
/> 

RESULT: An error has occured while trying to execute query :[LDAP: error code 1 - 000004DC: LdapErr: DSID-0C0906E8, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db1 ].

Does CFLDAP support this scenario? (bind using provably-authenticated current user)
