Splunk for AD - Group Policy Changes Query

Hello,
Has anyone come across an issue where the Group Policy Change Management information wont load?

I discovered its because the "Object_Name" is not a DN value sometimes.

When I run this:

eventtype=msad-ad-access Object_Type="groupPolicyContainer" | eval adminuser=src_nt_domain."\".src_user | eval Object_Name=replace(Object_Name,"}CN","},CN") | stats count values(Object_Name) by host

I get variations like this:
CN={6426A7DE-BDD3-4124-AD09-93782F200DE0},CN=Policies,CN=System,DC=domain
{44e14ec4-6218-40bd-bbc1-bf16d5addb58}

Why would that be?

I confirmed my DS log entries sometimes have either notation even for the same server.

Thank you for your help.

I've not seen the GUID version before. I normally see the full DN - either complete or missing a comma (which is handled by the eval statement). As a result, we'll have to deal with this as a bug and fix it in a future release.

I've filed this in our bug tracking system.

Do we know when this might be fixed? We have the same issue where the Group Policy is a GUID in the logs but have a full DN. Also this is generating the following error.

I seem to get the same thing- Trying to figure out a work around as the AD guys would love to see Group Policy Changes.
