I already installed this app along with the TA and it seems working okay with not many visio displays, but that's alright.
The issue is that there is no where in the log I can find the organization unit (OU) where a user belongs to.
Anyone knows how/where I can find the OU names?
This is not currently available. I wrote some code really quick, and in v1.3.2 ( or v1.4.0 not sure on version yet) I will have a new sourcetype "gapps:admin:directory:users" that will list all of the user information, including org. Be careful though, this may expose PII into your Splunk environment. But the option is there.
