IZ06696: INCREASED ROBUSTNESS FOR THE DB2 AUTHENTICATION PLUGIN CODE.

DB2 UDB Version 8.1 FixPak 16 (also known as Version 8.2 FixPak 9 )

APAR status

• Closed as program error.

Error description

• This APAR has been entered to make the authentication plugin
  interface code more robust.  This is a defensive fix to increase
  sanity checks of the values passed from third party plugins to
  DB2 during authentication.  If a bad structure is passed during
  authentication, it could cause db2 to trap and halt the
  instance.  Often there is no stack trace in the associated trap
  file, most likely due to stack corruption.
  

Local fix

• n/a
  

Problem summary

• Users affected:  Users with a custom authentication plugin
  Problem Description: Code was added to increase robustness of
  the code the interfaces with custom plugins
  Problem Summary:  see above

• Problem was first fixed in Version 8.1 FixPak 16
