Getting Data In

Active Directory User Logon Failures

I've got the Active Directory app installed, and everything is working except the User Logon Failures tab. The search is:

search eventtype=msad-failed-user-logons (host="HOSTNAME") | fields _time,signature,src_ip,src_host,src_nt_domain,user,Logon_Type

However, the data is coming in tagged with the host as "HOSTNAME.domain". If I modify the search manually to say:

search eventtype=msad-failed-user-logons (host="HOSTNAME.domain") | fields _time,signature,src_ip,src_host,src_nt_domain,user,Logon_Type

Everything works. Is there a conf file I need to change somewhere?

The host field is set on the Universal Forwarder configuration, and we expect it to be the plaintext host without the domain, which is normally how it happens. Unfortunately, the app is not written in a way that support host.domain tagging for the host. You will need to modify the app to support that.

Please feel free to file an enhancement request with out support group if you have a support contract.

Maybe I'm not explaining it right. The data is coming in tagged as "domaincontroller.domain", but I want it to be tagged as "domaincontroller". All the other data from the same domain controller, using the universal forwarder, is tagged as "domaincontroller". Why are the fields for the security stuff tagged differently?

I don't understand. I installed the Universal Forwarder on 5 domain controllers, as it required for the active directory app. Considering everything I've done is a completely out-of-the-box install, how can it not work?

No, if I select "Security" then "User Utilization", it says "No matching fields exist", and no results under any of the boxes.

I just added hat. Is there any way to test that app?

Assuming your on 1.1.4 since you just installed, check in your ldap.conf file and add the attribute alternatedomain in your domain stanza; so it will look something like:

[HOSTNAME.domain]
alternatedomain=HOSTNAME
