LDAP Request Monitoring

[Error401]

Hello,

I'm a complete newbie to Splunk so correct me if I'm wrong somewhere.

I'm trying to monitor LDAP request, I have more than 21sites in our Domain.

I'm using the Splunk App for Windows Infrastructure and IT Operation.

Is there any way I can get 30days LDAP request from these applications or Splunk.

I'm taking out the logons weightage but it is taking almost forever to even get 5 days records -

Note - I don't have any admin privilege and no configuration can be allowed in the Splunk. Only READ-ONLY mode is available, I cannot run any query.

HELP ME SUGGEST SOMETHING SO THAT I CAN GET THE LDAP REQUESTS FROM THE DC.

TOTAL DC COUNT - 69

THANKs
