Hi,

I am parcing a log file and generating the report. The report contains the user and few other fields related to application. I need to find an attribute of the user fetched from log and create a new field with the value. Ex, in the ldap, need to fetch organization and email address of the user identified in logs. Could you please guide me achieve this!!
