Problems Connecting To Active Directory Using LDAP

Hello. I am trying to have our Barracuda Spam Firewall 300 verify incoming email addresses against Active Directory using LDAP. I can telnet and login just fine, so I am sure that everything is running correctly. The Barracuda requires the following information:

LDAP Server: 10.0.0.2 (SBS 2003)
LDAP Port: 389 (which I can telnet to)
BIND DN: User (I have created a user within AD that has only Domain User rights; I can telnet fine with this User).
BIND Password: user's password
LDAP Filter: using the default ((|(proxyaddress=smtp:${recipient_email})(mail=${recipient_email}))
LDAP Search Base: default (${defaultNamingContext}
LDAP UID: deafult for AD: sAMAccountName
Valid Email For Testing: my valid email address

When I try to test this I receive the following error:

could not set open file limit to 8192: Operation not permitted
lookup order: fb
listening on localhost/59447
answering client connection request from 127.0.0.1/59448
received from 127.0.0.1/59448: GET user@domain.com
email address: user@domain.com
telling 127.0.0.1/59448: 200 550 DB verification agent failed%3A
received from 127.0.0.1/59448: QUIT
hanging up on client 127.0.0.1/59448
exiting on SIGTERM

I am new to LDAP and have no clue as to where to go from here. I have posted this to the Barracuda forums, but have received no response as of yet.

Thank you.

Thanks for the reply. I have already created a user for the Barracuda's use and that is what I am using as the BIND DN (user@domain.com). Byt I still get this error.

Thanks, Chris. I am out of the office, but will try this on Monday.
Hi, Chris:

Tries using the full DN, but still no joy. I can bind with this user using ldp.exe, so I am unsure what the issue may be.
