Pass-through Login
Flag to indicate whether pass-through login is enabled or not.
Data Type
string
Default Value
""
Remarks
Disabled (default)—This allows automated provisioning of a connection pool. Open connection threads can be used by authorized users after the validation query verifies connection status. If pass-through login is disabled, the Save Password check box is not available.
Enabled—A new connection to the data source uses the credentials supplied by the client when data is requested from that data source for the first time. Subsequent requests by the same user reuse the existing connection. When another user attempts to connect to a data source, a new connection is created.
See “Managing Security for TDV Resources” in the TDV Administration Guide for details.
