How to extract fields from /services/authentication/current-context?

Cbr1sg — Mon, 04 Jun 2018 03:16:13 GMT

Hello all,
The command
| rest /services/authentication/current-context
will return some fields like username, email, realname, etc..
I want to get other fields on LDAP like Telephone Number, SIP address, etc..
Is it possible?
Thanks

Well, you can always define regular expressions to fetch needed field value, are you looking to extract ALL fields automatically? There is limitations on that

can you post a sample of your events as they appear in splunk?

You'll need a secondary data source, e.g. ldapsearch, to retrieve that information, use the username returned by current-context as a filter.

I think you might have misunderstood my question, and sorry as I wasn't clear enough.

I want to get additional information which does NOT exist in current-context,
When the user authenticates using LDAP username/password, Splunk does the ldap lookup and returns some of standard fields like username, email, realname, etc..
Besides those fields, i want to get something else which is missing, for example Phone and SipAddress

i already looked into this, unfortunately my server is linux so this solution is not compatible, do you have other suggestion for linux? Thanks

SA-ldapsearch runs on linux splunk servers.

If you don't have AD, consider https://splunkbase.splunk.com/app/3872/
