The Radius plug-in for iManager requires a secure LDAP connection.

When extending free radius schema in iManager the error returned is:
  Created LDAP context failed: 
  Connect Error
  java.lan.Exception\n at com.novell.nps.radius.ExtendRadiusSchema.showInitialForm(\n

When creating a Radius Profile or Radius User the following error is returned:
java.lang.NullPointerException at com.novell.nps.radius.RadiusSchema.isSchemaValid(


Check that the keystore (cacerts file) is valid and has the correct permissions. (For OES 2018.1 servers, see the OES 2018.1 sub-section below)

First find the JAVA_HOME path 
export |grep -i JAVA_HOME
usually returns something like this:

The keytool binary will usually be located in
And the keystore will usually be in the following location with the name of

Next check the permissions on the cacerts
ls -al /usr/lib64/jvm/jre/lib/security/cacerts
-rwxr-xr-x 1 root root  cacerts*
If the permissions are incorrect change the permissions with command:
chmod 755 /usr/lib64/jvm/jre/lib/security/cacerts

If the cacerts is missing expired because the CA was expired or recreated use the keytool command to generate a new cacerts file.
To verify that the CA is valid see TID 7013047

Once the CA if validated export a certificate from the tree via iManager.  If there is a OES server in the tree use the /etc/opt/novell/certs/SSCert.der
To export a cert with iManager, login to iManager | Novell Certificate Server | Configure Certificate Authority | Select the Certificates tab | Select the Self Signed Certificate tab | Export | Uncheck the "Export private key" option | Verify the Export format is "Der" | Next | Click "Save the exported certificate" link and save to the desired location.

Next, run the keytool command:
keytool -import -alias Alias_Name -file /path_to_exported_cert.der -keystore /path_to_cacerts file
 keytool -import -alias Alias_Name -file /etc/opt/novell/certs/SSCert.der /usr/lib64/jvm/jre/lib/security/cacerts
When prompted for password, type "changeit" and to the question "Trust this certificate?"answer "yes"

OES 2018.1:
Certificate path on OES server: /etc/opt/novell/certs/SSCert.der
keytool path: /usr/lib64/jvm/java-1_8_0-ibm-1.8.0/jre/bin/keytool
java keystore path: /var/lib/ca-certificates/java-cacerts

/usr/lib64/jvm/java-1_8_0-ibm-1.8.0/jre/bin/keytool -import -file /etc/opt/novell/certs/SSCert.der -keystore /var/lib/ca-certificates/java-cacerts
rcnovell-tomcat restart

Additional Information

See TID 7002490 for creating the keystore for a workstation version of iManager
or copy a valid keystore (the cacerts file) from a server or another workstation.
