Getting text from raw event with regex

[g_paternicola]

Hi everyone, 

I'm trying to get a simple text from a raw event, but I can't make it works.

The event looks like this:

and my regex looks like this:

| rex field=_raw "Allow\s(?<GroupName>\w.+)\s+Enroll" 

my issue is, that I only going to get a few of those groups, but not all... for example I will get the Domain Users but not the Enterprise Users which is in the same raw file...

Could please someone help me with this regex?

It's not clear to me what the problem is, but I think the rex command is not extracting all instances of the "Allow" field.  If so, then the max_match option should help.

| rex field=_raw max_match=0 "Allow\s(?<GroupName>\w.+)\s+Enroll"
