If this is set to
1 or
yes, DCAS is invoked internally rather than using a DCAS listener
Properties:
Default:
no
Values:
Yes, Y, 1, No, N, 0
Comments:
When Express Login Facility (ELF) is used with TN3270, and the TN3270 client triggers ELF processing by sending a client certificate
during connection establishment and subsequently including an ELF token in the input data stream, the TN3270 listener must
make a request to the Digital Certificate Authentication Service (DCAS). In
Enterprise Server 5.0 and earlier, it was necessary to define a DCAS listener in the
enterprise server region to provide this service. Beginning with
Enterprise Server 6.0, the TN3270 listener can instead invoke DCAS directly, without requiring that a listener be defined. This is known as
internal DCAS.
We encourage those who use DCAS only for ELF to use internal DCAS. This prevents any possible security issues with having
a DCAS listener potentially exposed to hostile clients.
Normally, DCAS is configured using the DCAS listener. When internal DCAS is used, the DCAS configuration can be supplied in
the configuration area for the TN3270 listener by prefixing each DCAS section name with "DCAS". For example:
