LDAP Access - javax.naming.CommunicationException: simple bind failed

We are running into issues connecting LDAP server after LDAP SHA-256 Migration .We got the below exception when we ran our application in debug mode :

javax.naming.CommunicationException: simple bind failed: [Root exception is Socket is closed]​

We tried to add the below .cer files into our application specific cacerts file:

  1. GlobalSignRootCA.cer

  2. GlobalSignOrganizationValidationCA-G2.cer

  3. OrganizationValidationCA-SHA256-G2.cer

After adding the above .cer file in cacerts ,we are getting different exception :

getLdapContactInfo(): javax.naming.CommunicationException: simple bind failed: [Root exception is Certificate signature validation failed]

Server :

Perl Web Farm Server

Java Version :

xxxxx@yyyy:~/www $ java -version

java version "1.4.2_19"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_19-b04)
Java HotSpot(TM) Client VM (build 1.4.2_19-b04, mixed mode)

Any help or suggestion on this regard is greatly appreciated.

Note: SUN JRE has been implemented in Server level and our application is IBM JRE under the
folder. We tried adding certificate(mentioned above) in "cacerts" under
but nothing worked.

I sorted out why am getting the above exception. The above 3 .cer files are not compatible to Java 1.4.2. So i tried pointing my application to Java 1.6 and the issue got resolved. Am able to retrieve information from the LDAP server.
