Myrna van Lunteren updated DERBY-1517:
--------------------------------------
Issue Type: Improvement (was: Bug)
> Derby Network Client to handle list of SECMEC(s) returned by
> existing/released DRDA Derby Network Servers
> ---------------------------------------------------------------------------------------------------------
>
> Key: DERBY-1517
> URL: https://issues.apache.org/jira/browse/DERBY-1517
> Project: Derby
> Issue Type: Improvement
> 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
>
> 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...
