SSL errors for security

You might encounter various problems after configuring or enabling SSL. You may not be able to stop the dmgr after configuring the SSL. You may not be able to access resource using HTTPS. The client and the server may not be able to negotiate the proper level of security. The problems mentioned here are only a few of the possibilities. Solving these problems is imperative to the successful operation of WAS.

What type of problem are you having?



Stop the dmgr after configuring SSL

After configuring the SSL repertoires, if you stop the dmgr without also stopping the node agents, you might receive the following error message when you restart the dmgr: 

CWWMU0509I: The server "nodeagent" cannot be reached. It appears to be stopped.
CWWMU0211I: Error details may be seen in the file:
           /opt/WebSphere/AppServer/logs/nodeagent/stopServer.log

The error occurs because the dmgr did not propagate the new SSL certificate to the node agents. The node agents are using an older certificate file than the dmgr and the certificate files are incompatible.

To work around this problem, manually stop the node agent and dmgr processes.

(Windows) To end the processes, use the Task Manager.

Run the command to end the process

You need to consider certain items when identifying the specific process to stop. For each process that is stopped, WAS stores the process ID in a pid file and find these *.pid files. For example, the server1.pid for a stand-alone install action might be found at: install_root/logs/server1.pid


Access resources using HTTPS

If you are unable to access resources using a SSL URL (beginning with https:), or encounter error messages that indicate SSL problems, verify that your HTTP server is configured correctly for SSL. Browse the welcome page of the HTTP server using SSL by entering the URL: https://host_name.

If the page works with HTTP, but not HTTPS, the problem is with the HTTP server.

If the HTTP server handles SSL-encrypted requests successfully, or is not involved (for example, traffic flows from a Java client application directly to an enterprise bean that is hosted by WAS, or the problem displays only after enabling WAS security), what kind of error are you seeing?

You get this error message org.omg.CORBA.INTERNAL: EntryNotFoundException or NTRegistryImp E CWSCJ0070E: No privilege id configured for: when programmatically creating a credential

javax.net.ssl.SSLHandshakeException - The client and server could not negotiate the desired level of security. Reason: handshake failure

If you see a Java exception stack similar to the following example: 

[Root exception is org.omg.CORBA.TRANSIENT:  CAUGHT_EXCEPTION_WHILE_CONFIGURING_
SSL_CLIENT_SOCKET: CWWJE0080E:   javax.net.ssl.SSLHandshakeException - The client and server could not negotiate the desired level of   security. Reason: handshake
failure:host=MYSERVER,port=1079 minor code: 4942F303 completed: No]   at
com.ibm.CORBA.transport.TransportConnectionBase.connect
(TransportConnectionBase.java:NNN)

Some possible causes are:

To correct these problems:

  1. Review the SSL settings. In the administrative console, click Security > SSL certificate and key management. Under Configuration settings, click Manage endpoint security configurations > endpoint_configuration_name. Under Related items, click SSL configurations > SSL_configuration_name. We can also browse the file manually by viewing the install_root/properties/sas.client.props file.
  2. Check the property specified by the com.ibm.ssl.protocol file to determine which protocol is specified.
  3. Check the cipher types specified by the com.ibm.ssl.enabledCipherSuites interface. You might want to add more cipher types to the list.

    To see which cipher suites are currently enabled, click Quality of protection settings (QoP), and look for the Cipher Suites property.

  4. Correct the protocol or cipher problem by using a different client or server protocol and cipher selection. Typical protocols are SSL or SSLv3.

  5. Make the cipher selection 40-bit instead of 128-bit. For Common Secure Interoperability Version 2 (CSIv2), set both of the following properties to false in the sas.client.props file, or set security level=medium in the administrative console settings:

    • com.ibm.CSI.performMessageConfidentialityRequired=false
    • com.ibm.CSI.performMessageConfidentialitySupported=false



javax.net.ssl.SSLHandshakeException: unknown certificate

If you see a Java exception stack similar to the following example, it might be caused by not having the personal certificate for the server in the client truststore file: 

ERROR: Could not get the initial context or unable to look up the starting context.
Exiting.  Exception received: javax.naming.ServiceUnavailableException: A
communication failure occurred while attempting to obtain an initial context using
the provider url: "corbaloc:iiop:localhost:2809". Make sure that the host and port information is correct and that the server identified by the provider url is a
running name server. If no port number is specified, the default port number 2809
is used. Other possible causes include the network environment or workstation
network configuration. [Root exception is org.omg.CORBA.TRANSIENT:
CAUGHT_EXCEPTION_WHILE_CONFIGURING_SSL_CLIENT_SOCKET: CWWJE0080E:
javax.net.ssl.SSLHandshakeException - The client and server could not
negotiate the desired level of security. Reason: unknown
certificate:host=MYSERVER,port=1940 minor code: 4942F303 completed: No]

To correct this problem:

  1. Check the client truststore file to determine if the signer certificate from the server personal certificate is there. For a self-signed server personal certificate, the signer certificate is the public key of the personal certificate. For a certificate authority (CA)-signed server personal certificate, the signer certificate is the root CA certificate of the CA that signed the personal certificate.

  2. Add the server signer certificate to the client truststore file.


javax.net.ssl.SSLHandshakeException: bad certificate

A Java exception stack error might display if the following situations occur:

The following message is an example of the Java exception stack error: 

ERROR: Could not get the initial context or unable to look
up the starting context. Exiting.
Exception received: javax.naming.ServiceUnavailableException:
A communication failure occurred while attempting to obtain an
initial context using the provider url: "corbaloc:iiop:localhost:2809".
Make sure that the host and port information is correct and that the server identified by the provider url is a running name
server. If no port number is specified, the default port number 2809
is used. Other possible causes include the network environment or
workstation network configuration.
[Root exception is org.omg.CORBA.TRANSIENT: CAUGHT_EXCEPTION_WHILE_CONFIGURING_SSL_
CLIENT_SOCKET: CWWJE0080E: javax.net.ssl.SSLHandshakeException - The client and
server could not negotiate the desired level of security. Reason:
bad certificate: host=MYSERVER,port=1940 minor code: 4942F303 completed: No]

To verify this problem, check the server truststore file to determine if the signer certificate from the client personal certificate is there. For a self-signed client personal certificate, the signer certificate is the public key of the personal certificate. For a certificate authority-signed client personal certificate, the signer certificate is the root CA certificate of the CA that signed the personal certificate.

To correct this problem, add the client signer certificate to the server truststore file.


org.omg.CORBA.INTERNAL: EntryNotFoundException or NTRegistryImp E CWSCJ0070E: No privilege id configured for: error when programmatically creating a credential

If you encounter the following exception in a client application attempting to request a credential from a WAS using SSL mutual authentication: 

ERROR: Could not get the initial context or unable to look up the starting context.
Exiting. Exception received: org.omg.CORBA.INTERNAL: Trace from server: 1198777258
at host MYHOST on port 0 >>org.omg.CORBA.INTERNAL: EntryNotFoundException minor
code: 494210B0 completed:
No at com.ibm.ISecurityLocalObjectBaseL13Impl.PrincipalAuthFailReason.
map_auth_fail_to_minor_code(PrincipalAuthFailReason.java:99)

or a simultaneous error from the WAS that resembles: 

[7/31/02 15:38:48:452 CDT] 27318f5 NTRegistryImp E CWSCJ0070E: No privilege id
configured for: testuser

The cause might be that the user ID sent by the client to the server is not in the user registry for that server.

To confirm this problem, check that an entry exists for the personal certificate that is sent to the server. Depending on the user registry mechanism, look at the native operating system user ID or LDAP server entries.

To correct this problem, add the user ID to the user registry entry (for example, operating system, LDAP directory, or other custom registry) for the personal certificate identity.


"Catalog" tablet is blank (no item displayed) in GUI application client

This error message occurs when you install an ActiveX client sample application that uses the PlantsByWebSphere Active X to EJB Bridge.

The cause is that the server certificate is not in the client trustore specified in the client.ssl.props file. Although the "com.ibm.ssl.enableSignerExchangePrompt" signer property might be set to true, the auto-exchange prompt only supports a command-line prompt. If the sample application relies on a graphical user interface and does not provide access to a command prompt, for example using standard in and standard out, the auto-exchange prompt does not function.

The applet client under the Client Technology Samples does not have access to the command prompt and it cannot see the auto-exchange prompt. Thus, the applet client cannot rely on the auto-exchange prompt feature.

To correct this problem, retrieve the certificate manually using the retrieveSigners utility.


Modify SSL Configurations after migration using -scriptCompatibility true

After migrating using scriptCompatibility true, all attributes of the SSL configurations cannot be edited through the administrative console. In particular, the hardware cryptography settings cannot be displayed or edited.

By using the scriptCompatibility true flag, the SSL configurations are not migrated to the new format for support in the v6.1 and later releases. New capabilities were added that are not supported when the configurations are not migrated to the latest format. If you are migrating from a release prior to v6.1, you can use the convertSSLConfig task to convert your SSL configuration information to the centralized SSL configuration format.


Stand-Alone configuration fails when digital certificates are defined with the NOTRUST option

If your digital certificates are defined with the NOTRUST option, it is possible that you might receive the following error message: 

Trace: 2008/06/18 16:57:57.798 01 t=8C50B8 c=UNK key=S2 (0000000A)
Description: Log Boss/390 Error

Too many open files. (errno2=0x0594003D)??

If this error appears, enter 'D OMVS,P. If we have a NOTRUST issue a large number appears under 'OPNSOCK'.

Check your digital certificates and make sure they are not marked with the NOTRUST option. This can occur if the certificates were created with a date beyond the expiration date of the CERTAUTH that was used to create it.


Problem when configuring an LDAP repository with SSL

When configuring an LDAP repository with SSL, configure the LDAP repository on the node before the node is registered with the admin agent.

If you attempt to configure the LDAP repository after registering the node with the agent, federated repositories looks for the SSL certificates in the trust store of the admin agent instead of in the trust store of the node.
