Active Directory Integration Fails with Trend Micro Interscan Web Security Virtual Appliance (IWSVA)

Hi all,

I come to you with the reason to make the following query:

When I want to synchronize the Trend Micro IWSVA product against my Active Directory from the Web console that provides that product, I get the following error:

"The LDAP connection is not established Because unknown error"

After checking IWSVA logs and checking for a proper connectivity between IWSVA and Active Directory (name resolution, open ports, timed schedule, etc), I came to the conclusion that the problem should come from Active Directory.

When performing a packet capture, I could find the following errors, which I promptly interested the second:

1) - LDAPMessage BindResponse (3) strongAuthRequired (00,002,028: LdapErr: DSID-0C0901FC, comment:The server requires binds to turn on integrity checking if SSL \ TLS are not Already active on the connection,data 0, v1db1)

2) - LDAPMessage BindResponse (2) invalidCredentials (80,090,302: LdapErr: DSID-0C0904DC, commented:AcceptSecurityContext mistake, data 1, v1db1)

(I clarify that we tested with 3 different service accounts, all with Administrator rights. And have always received the same error)

Could you tell me they mean error codes "Data 1" and "Data 0" ?

I can not find information about these types of errors , unlike other errors which if published information .

I appreciate any help you can give me.

Thank you.

Best regards.
