Splunk App for Windows Infrastructure - deployment issues

africates — Mon, 28 Sep 2020 17:22:44 GMT

Hi,

I'm trying to deploy Splunk App for Windows Infrastructure on small AD environment (2 Domain Controllers and few other windows servers + 1 Splunk Indexer)

I installed everything according to the App specification but I'm getting very little information via the App itself now. I can see that I do not get any info re users or groups etc.

I noticed that powershell scripts aren't running OK i.e. below script should gather some Topology info but returns error (see the end of the post).

Any ideas what could go wrong?

[powershell://AD-Health]
script = & "$SplunkHome\etc\apps\TA-DomainController-2012R2\bin\Invoke-MonitoredScript.ps1" -Command ".\ad-health.ps1"
schedule = 0 */5 * ? * *
index = msad
source=Powershell
sourcetype=MSAD:NT6:Health
disabled=false

Hi africates,
Did you verify your ldap.conf?...
The following can also help

Hi,

I had configured ldap.conf on the Splunk server (\\c$\Program Files\Splunk\etc\apps\SA-ldapsearch\local\ldap.conf) - see the config below.

I also enabled auditing and Powershell script execution on AD servers via GPO.

The only thing which I skipped from the whole installation guide was setting up AD user for Splunk server. Instead of that I am running Splunk server service as domain administrator temporarily which I believe should be fine.

Any other ideas? Maybee there is some way of debugging the whole process?

[default]
server =

[my-domain.local]
server = ;
basedn = DC=my-domain,DC=local
binddn = cn=user,OU=Managed Service Accounts,DC=my-domain,DC=local
password = xxx
alternatedomain = MY-DOMAIN

thanks
p

OK, I think I'm getting somewhere.. I am able to run 'ldapsearch' using Splunk Support - LDAP Commands app. I can also see some indexes triggered by add-ons installed on DC (i.e. for TA-DomainController-2012R2 when executing: index=msad sourcetype=MSAD:NT6:Health).
I still however have problem with Splunk App for Windows Infrastructure. When I'm running 'App Configuration' I'm not getting: Users, Computers and Groups.
I was under impression that these are preconfigured in addons which I installed on the DCs but maybe these are not. What I should chec in inputs.conf? thanks

I ignored that Users, Computers and Groups weren't detected and checked these under 'App Configuration' & created lookups. I can see some reports when I do the search now but i.e. below (+more) are missing:
Users>Administrator Audit (Account Domain and Administrator - no results)
