Index fails with error code 20002.
DLP 15.x.
Issue is due to a user that does not match with the user in the database from a previous sync.
Check the localhost log for the user that caused the failure.
There are three solutions.
1.) Customer may not even be using the feature. This feature is used for risky users in the dashboard view. If it is not being used remove the AD user sync.
2.) Open a sqlplus /nolog connection from the cmd window and specify the bad user:
SELECT * FROM DATAUSER WHERE FIRSTNAME = '<user>';
DELETE FROM DATAUSER WHERE FIRSTNAME = '<user>';
3.) Delete the entire table contents so that on next sync we will repopulate the database.
DELETE FROM DATAUSER;
