We are facing this error in MS SQL Server extension: MS SQL DB end point- Port 1433: [ONGOING] - Failed to schedule polling with message 'Error when adding connection management layer to datasource - Login failed. The login is from an untrusted domain and cannot be used with Integrated authentication. ClientConnectionId:** [SQLState: S0001, ErrorCode: 18452]'. Retry will be done in the next interval..

If some one could help on this, appreciate it.

Hi,

I would try to involve some DBA about that. Was user created correctly in database level? Is password expired?

Best regards
