Derby Network Client to handle list of SECMEC(s) returned by existing/released DRDA Derby Network
Servers
---------------------------------------------------------------------------------------------------------

                 Key: DERBY-1517
                 URL: http://issues.apache.org/jira/browse/DERBY-1517
             Project: Derby
          Issue Type: Bug
          Components: Network Client
         Environment: The Derby network client should be made capable of handling a list of
SECMEC(s) returned by previously released DRDA Derby network servers
            Reporter: Francois Orsini
             Fix For: 10.2.0.0


Currently, the Derby DRDA network server does not *properly* return the list of SECMEC(s)
it can support if a client is requesting to authenticate with a non-supported SECMEC (see
JIRA-926 - http://issues.apache.org/jira/browse/DERBY-926)

The motivation for this JIRA is to add the logic for the Derby client to be capable of parsing
the list of supported SECMEC(s) returned by previous released Derby network servers (pre-JIRA-926
Fix) - This is necessary for backwards compatibility with older servers - This issue has been
even more visible as Derby-528 introduces support for a new DRDA security mechanism (Strong
Password Substitute), which causes a DRDA protocol exception when trying to authenticate with
the new supported mechanism against older Derby DRDA servers (JIRA-926 issue)

JIRA-926 has to be fixed nonetheless on the server side to properly return the list of supported
SECMEC(s) in conformance with the DRDA (DDM) specs - This JIRA focuses on the client side
to do its best and be capable of parsing a list of SECMEC(s) returned pre-926 fix.

Ultimately, the derby network client can be made capable of parsing a list of SECMEC(s) from
pre-926 fixed (older) and post-926 fixed servers...
