IJ04910: WHILE USING LDAP CRL, THE CRL DISTRIBUTION POINT TIMEOUT VALUE IS IGNORED.

APAR status

• Closed as program error.

Error description

• Error Message: Some certificates use LDAP CRL endpoint for
  certificate revocation status validation.  When the CRL endpoint
  is not reachable, a Java thread that performs the CRL validation
  waits until the underlying network times out, resulting in slow
  response from the LDAP server.
  Setting com.sun.jndi.ldap.connect.timeout environment variable
  and com.ibm.security.crls.timeout system property settings do
  not have an impact since these values are ignored by the IBM
  SDK.
  .
  Stack Trace: N/A
  .
  The issue could result in a slow LDAP server response when LDAP
  server is not reachable.
  

Local fix

• Disable real-time CRL end points checking if the underlying
  network timeout value degrades the LDAP server?s response.
  

Problem summary

• While using LDAP CRL, CRL Distribution Point timeout value is
  ignored.
  

Problem conclusion

• A change is made to the IBM Certification Path Provider
  The associated Hursley RTC Problem Report is 137442
  The associated Austin CMVC defect is 117811
  JVMs affected: Java 7.0, Java 727 and Java 8.0
  The fix was delivered for Java 7.0 SR10FP25, Java 727 SR4FP25,
  and Java 8 SR5FP15
  The affected jar is "ibmcertpathprovider.jar"
  The build level of this jar for the affected releases is
  "20180307"
  The JVM has been updated to respond to time out values set by
  the user while using LDAP Distribution Point for checking
  Certificate revocation status. A timeout value is set before
  establishing a connection with LDAP server that is being used
  as. a CRL Distribution Point.
  The timeout value is determined as follows:
  The SDK first uses the environment property
  com.sun.jndi.ldap.connect.timeout.
  If the environment variable is not set, the SDK uses the
  com.ibm.security.crls.timeout system property.
  If the both the environment variable and the system property are
  not set, then the SDK uses a default timeout value of 15
  seconds.
  .
  This APAR will be fixed in the following Java Releases:
     8    SR5 FP15  (8.0.5.15)
     7 R1 SR4 FP25  (7.1.4.25)
     7    SR10 FP25 (7.0.10.25)
  .
