IT31578: Allow usernames in CHLAUTH rules to be matched case-insensitively

APAR status

• Closed as program error.

Error description

• Users who have a policy of case-insensitive username matching in
  their organisation found there was no explicit support for this
  in their CHLAUTH rules.
  

Local fix

• It is recommended that you ensure the usernames in CLNTUSER are
  of the correct case, rather than use this option.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users who have a policy of case-insensitive username matching
  for their CHLAUTH rules.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  Functionality is added to the MQ code to allow a queue manager
  to make username matching within CHLAUTH rules case-insensitive.
  

Problem conclusion

• Functionality is added to the MQ code to:
  - Allow the CLNTUSER in CHLAUTH TYPE(USERMAP) rules to be
  matched case-insensitively.
  - Allow the USERLIST in CHLAUTH TYPE(BLOCKUSER) rules to be
  matched case-insensitively.
  
  When this APAR fix has been applied (or a Fix Pack that includes
  it)...
  
  To enable the new behavior, add ChlauthIgnoreUserCase=YES in the
  Channels stanza of the qm.ini file.  If there is no Channels
  stanza, you will have to create one.  Refer to the Knowledge
  Center for details of adding stanzas to the qm.ini file.
  
  To enable the new behavior on the MQ Appliance, issue the
  following command, with your real queue manager name in the
  place of <YOUR-QMNAME>:
  
    setmqini -m <YOUR-QMNAME> -s Channels -k ChlauthIgnoreUserCase
  -v YES
