Getting Data In

How do I get the learned app to set owner to a valid user?

The learned app is creating objects owned by "nobody". This creates logged error messages about

ERROR AuthenticationManagerLDAP - Could not find user="nobody" with strategy="??????""  (????? is my own...)

I can find these with:

find ./ -name local.meta -exec grep -H 'nobody' {} \;

and they are coming from the learned app. I guess I would like to assign them to "admin" and have learned create further new sourcetypes with owner=admin. I can reassign existing ones with

find ./ -name local.meta -exec sed -i 's/owner = nobody/owner = admin/g' {} \;

How do I get future learned sourcetypes to default the owner to admin? (If defaulting the ownership to admin isn't good then please point out why and I will choose a different default user.)

Hi dleifer_mercury,

I have written a script that changes the owner. I used on the code from here and modified it for my use. This script will look for all files owned by a user from a specific objects, ex. Saved search. The type of object can be changed however manually this is to prevent errors. I would run this script every so often to identify and make ownership changes or use a cron job to automate it. I would however advise against the latter to have complete control of changes.

#!/bin/bash
#This script is intended to replace all search/alerts/reports owned by "No owner" aka nobody

#Timestamp used for logs
_now=$(date +"%Y-%m-%d %H:%M:%S")

read -s password

# Reference: http://wiki.splunk.com/Community:How_to_change_owner_of_savedsearches_using_REST_API
# Be careful ! REST does not have a good error checking. You might mess up the result by mistake.
# Note: if sharing is not specified, you're trying to make it as global. But, if the object is private, you cannot change permission to global implicitly, and get error.
# Note: This will return REST call return. I'm not showing the returns here (header names)
