We are working with several remote datasets that are combined to give our end user a specific result.  Federated Search gives us an LDAP dn, which we are trying to use to pull enhancing information from another remote source via a REST API.  The following search works:   index=federated:remote_dataset userid="cn=" | \ eval dn=lower(userid) | \ dedup dn | \ table dn   The idea is to use a scheduled search to populate a csv with a list of DNs at the top of every hour, then use a cron job to spawn a python script which generates a new CSV that contains the DN and the enhancing data from the REST API source. Our python script is working, however when we add "|outputlookup dn.csv append=true" to the otherwise functional SPL, we get nothing. This fails:   index=federated:remote_dataset userid="cn=" | \ eval dn=lower(userid) | \ dedup dn | \ table dn | \ outputlookup dn.csv append=true   Is this a limitation of Federated Search?
