APAR status

• Closed as program error.

Error description

• When specifying multiple environment variables in a directive,
  IHS will only use the last environment variable's value found
  for all the previous environment variables.
  
  An example of this is:
  bin/envvars:
  export LEVEL=TEST
  export SYSTEM=MVS1
  
  conf/httpd.conf:
  AuthName "${SYSTEM}-${LEVEL}-IHS"
  

Local fix

• use only 1 environment variable in a directive

  The memory returned by getenv() is likely to be  be reused by
  subsequent calls to getenv().
  

Problem conclusion
