Cause

The probe data engine parameters is configured with Integrated Security=SSPI

parameters = Network Library=dbmssocn;Language=us_english;Integrated Security=SSPI

This parameters is the same as Integrated Security=true;

This parameters force the secondary hub to connect to the Database as windows user authentication.

Environment

Secondary Hub with probe HA configured with Microsoft SQL server

Resolution

Remove the Integrated Security=SSPI from the parameters on the data_engine.cfg on the HA hub.

change this line:

parameters = Network Library=dbmssocn;Language=us_english;Integrated Security=SSPI

to

parameters = Network Library=dbmssocn;Language=us_english

Restart the data_engine probe.
