IT37876: IDLE LDAP CONNECTION MAY MAKE THE INTEGRATION NODE UNREACHABLE.

APAR status

• Closed as program error.

Error description

• The connection to LDAP server may become dead and unusable if
  the integration node, configured to use LDAP for administration
  security, is kept idle for a long period of time. This may block
  connections to the integration node till it restarts.
  

Local fix

• N/A
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM App Connect Enterprise V12 and V11 using LDAP
  for administration security.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When using LDAP for administration security in ACE, the
  connection to LDAP server may become dead and unusable if the
  integration node is kept idle for a long period of time. This
  may block connections to the integration node till it restarts.
  

Problem conclusion

• A new property named ldapIdleTimeout is introduced which can be
  set in the node.conf.yaml or server.conf.yaml(for stand-alone
  integration servers) under RestAdminListener section. The value
  is specified in milliseconds and it signifies the allowed idle
  period of time after the last LDAP operation. If no LDAP
  activity is performed and the idle period of time is exceeded
  then the LDAP connection is closed. A new connection will be
  made when an LDAP authentication or authorization attempt is
  made after the idle period.  The default value of the property
  is 0  which means 'never close connection'.
  
  e.g: The following is a setting to close LDAP connection when it
  is idle for more than 1 hour.
  
  RestAdminListener:
    ldapIdleTimeout: 3600000
