Access problems after enabling security

Use this information if you are experiencing access problems after enabling security.

New feature: Beginning in WAS v8.0 you can configure the server to use the High Performance Extensible Logging (HPEL) log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.New feature:

I cannot access all or part of the administrative console or use wsadmin.sh after enabling security

• If you cannot access the administrative console, or view and update certain objects, look in the SystemOut log of the application server which hosts the administrative console page for a related error message.

• You might not have authorized your ID for administrative tasks. This problem is indicated by errors such as:
  • [8/2/02 10:36:49:722 CDT] 4365c0d9 RoleBasedAuth A CWSCJ0305A: Role based authorization check failed for security name MyServer/myUserId, accessId MyServer/S-1-5-21-882015564-4266526380-2569651501-1005 while invoking method getProcessType on resource Server and module Server.
  • Exception message: "CWWMN0022E: Access denied for the getProcessType operation on Server MBean"

  • When running the command: wsadmin -username j2ee -password j2ee: CWWAX7246E: Cannot establish "SOAP" connection to host "BIRKT20" because of an authentication failure. Ensure that user and password are correct on the command line or in a properties file.

  To grant an ID administrative authority, from the administrative console, click System Administration > Console Users and validate that the ID is a member. If the ID is not a member, add the ID with at least monitor access privileges, for read-only access.

• Verify that the trusted application functionality is enabled. The trusted application functionality is enabled if WAS has SAF access of READ to the RACF class of FACILITY, and profile of BBO.TRUSTEDAPPS. <cell short name>. <cluster short name>.

I cannot access a web page after enabling security

When secured resources are not accessible, probable causes include:

• Authentication errors - WAS security cannot identify the ID of the person or process. Symptoms of authentication errors include:

  On a Netscape browser:

  • Authorization failed. Retry? message is displayed after an attempt to log in.
  • Accepts any number of attempts to retry login and displays Error 401 message when Cancel is clicked to stop retry.
  • A typical browser message displays: Error 401: Basic realm='Default Realm'.

  On an Internet Explorer browser:

  • Login prompt displays again after an attempt to log in.
  • Allows three attempts to retry login.
  • Displays Error 401 message after three unsuccessful retries.

• Authorization errors - The security function has identified the requesting person or process as not authorized to access the secured resource. Symptoms of authorization errors include:
  • Netscape browser: "Error 403: AuthorizationFailed" message is displayed.

  • Internet Explorer:
    • "You are not authorized to view this page" message is displayed.
    • "HTTP 403 Forbidden" error is also displayed.

• SSL errors - WAS security uses SSL technology internally to secure and encrypt its own communication, and incorrect configuration of the internal SSL settings can cause problems. Also you might have enabled SSL encryption for your own web application or enterprise bean client traffic which, if configured incorrectly, can cause problems regardless of whether WAS security is enabled.
  • SSL-related problems are often indicated by error messages that contain a statement such as: ERROR: Could not get the initial context or unable to look up the starting context.Exiting. followed by javax.net.ssl.SSLHandshakeException

The client cannot access an enterprise bean after enabling security

If the client access to an enterprise bean fails after security is enabled:

• Review the steps for securing and granting access to resources.

• Browse the server JVM logs for errors relating to enterprise bean access and security. Look up any errors in the message table.

  Errors similar to Authorization failed for /UNAUTHENTICATED while invoking resource securityName:/UNAUTHENTICATED;accessId:UNAUTHENTICATED not granted any of the required roles roles indicate that:

  • An unprotected servlet or JSP file accessed a protected enterprise bean. When an unprotected servlet is accessed, the user is not prompted to log in and the servlet runs as UNAUTHENTICATED. When the servlet makes a call to an enterprise bean that is protected, the servlet fails.

    To resolve this problem, secure the servlet that is accessing the protected enterprise bean. Make sure that the runAs property for the servlet is set to an ID that can access the enterprise bean.

  • An unauthenticated Java client program is accessing an enterprise bean resource that is protected. This situation can happen if the file that is read by the sas.client.props properties file used by the client program does not have the securityEnabled flag set to true.

    To resolve this problem, make sure that the sas.client.props file on the client side has its securityEnabled flag set to true.

  Errors similar to Authorization failed for valid_user while invoking resource securityName:/username;accessId:xxxxxx not granted any of the required roles roles indicate that a client attempted to access a secured enterprise bean resource, and the supplied user ID is not assigned the required roles for that enterprise bean.

  • Check that the required roles for the enterprise bean resource are accessed. View the required roles for the enterprise bean resource in the deployment descriptor of the web resource.
  • Check the authorization table and make sure that the user or the group that the user belongs to is assigned one of the required roles. We can view the authorization table for the application that contains the enterprise bean resource .

If org.omg.CORBA.NO_PERMISSION exceptions occur when programmatically logging on to access a secured enterprise bean, an authentication exception has occurred on the server. Typically the CORBA exception is triggered by an underlying com.ibm.WebSphereSecurity.AuthenticationFailedException. To determine the actual cause of the authentication exception, examine the full trace stack:

1. Begin by viewing the text following WSSecurityContext.acceptSecContext(), reason: in the exception. Typically, this text describes the failure without further analysis.

2. If this action does not describe the problem, look up the Common Object Request Broker Architecture (CORBA) minor code. The codes are listed in the article titled Troubleshoot the security components reference.

   For example, the following exception indicates a CORBA minor code of 49424300. The explanation of this error in the CORBA minor code table reads:

   authentication failed error
   

   In this case the user ID or password supplied by the client program is probably not valid:

   org.omg.CORBA.NO_PERMISSION: Caught WSSecurityContextException in WSSecurityContext.acceptSecContext(), reason: Major Code[0] Minor Code[0]
   Message[ Exception caught invoking authenticateBasicAuthData from SecurityServer
   for user jdoe. Reason: com.ibm.WebSphereSecurity.AuthenticationFailedException]
   minor code: 49424300 completed:
   No at com.ibm.ISecurityLocalObjectBaseL13Impl.PrincipalAuthFailReason.map_auth_fail_to_minor_code
   (PrincipalAuthFailReason.java:83)
   

A CORBA INITIALIZE exception with CWWSA1477W: SECURITY CLIENT/SERVER CONFIGURATION MISMATCH error embedded, is received by client program from the server.

This error indicates that the security configuration for the server differs from the client in some fundamental way. The full exception message lists the specific mismatches. For example, the following exception lists three errors:

Exception received: org.omg.CORBA.INITIALIZE:
CWWSA1477W: SECURITY CLIENT/SERVER CONFIG MISMATCH:
The client security configuration (sas.client.props or outbound settings in administrative console) does not support the server security configuration for
the following reasons:
ERROR 1: CWWSA0607E: The client requires SSL Confidentiality but the server does not
         support it.
ERROR 2: CWWSA0610E: The server requires SSL Integrity but the client does not
         support it.
ERROR 3: CWWSA0612E: The client requires client (e.g., userid/password or token),
         but the server does not support it.
     minor code: 0
     completed: No at
com.ibm.ISecurityLocalObjectBaseL13Impl.SecurityConnectionInterceptor.getConnectionKey
(SecurityConnectionInterceptor.java:1770)

In general, resolving the problem requires a change to the security configuration of either the client or the server. To determine which configuration setting is involved, look at the text following the CWWSA error message. For more detailed explanations and instructions, look in the message reference, by selecting the Reference view of the information center navigation and expanding Messages in the navigation tree.

In these particular cases:

• In ERROR 1, the client is requiring SSL confidentiality but the server does not support SSL confidentiality. Resolve this mismatch in one of two ways. Either update the server to support SSL confidentiality or update the client so that it no longer requires it.

• In ERROR 2, the server requires SSL integrity but the client does not support SSL integrity. Resolve this mismatch in one of two ways. Either update the server to support SSL integrity or update the client so that it no longer requires it.

• In ERROR 3, the client requires client authentication through a user id and password, but the server does not support this type of client authentication. Either the client or the server needs to change the configuration.

  To change the client configuration, modify the SAS.CLIENT.PROPS file for a pure client or change the outbound configuration for the server in the Security administrative console.

  To change the configuration for the target server, modify the inbound configuration in the Security administrative console.

Similarly, an exception like org.omg.CORBA.INITIALIZE: JSAS0477W: SECURITY CLIENT/SERVER CONFIG MISMATCH: appearing on the server trying to service a client request indicates a security configuration mismatch between client and server. The steps for resolving the problem are the same as for the JSAS1477W exceptions previously described.

Client program never gets prompted when accessing secured enterprise bean

Even though it seems that security is enabled and an enterprise bean is secured, occasions can occur when the client runs the remote method without prompting. If the remote method is protected, an authorization failure results. Otherwise, run the method as an unauthenticated user.

Possible reasons for this problem include:

• The server with which you are communicating might not have security enabled. Check with the WAS administrator to ensure that the server security is enabled. Access the security settings from within the Security section of the administrative console.
• The client does not have security enabled in the sas.client.props file. Edit the sas.client.props file to ensure the property com.ibm.CORBA.securityEnabled is set to true.
• The client does not have a ConfigURL specified. Verify that the property com.ibm.CORBA.ConfigURL is specified on the command line of the Java client, using the -D parameter.
• The specified ConfigURL does not have a valid URL syntax, or the sas.client.props that is pointed to cannot be found. Verify that the com.ibm.CORBA.ConfigURL property is valid. Check the Java documentation for a description of URL formatting rules. Also, validate that the file exists at the specified path.

  An example of a valid property is C:/WebSphere/AppServer/properties/sas.client.props.

• The client configuration does not support message layer client authentication (user ID and password). Verify that the sas.client.props file has one of the following properties set to true:
  • com.ibm.CSI.performClientAuthenticationSupported=true
  • com.ibm.CSI.performClientAuthenticationRequired=true

• The server configuration does not support message layer client authentication, which consists of a user ID and password. Check with the WAS administrator to verify that user ID and password authentication is specified for the inbound configuration of the server within the System Administration section of the administrative console administration tool.

Cannot stop an application server, node manager, or node after enabling security

If you use command-line utilities to stop WAS processes, apply additional parameters after enabling security to provide authentication and authorization information.

Use the ./stopServer -help command to display the parameters to use.

Use the following command options after enabling security:

• ./stopServer serverName -username name -password password
• ./stopNode -username name -password password
• ./stopManager -username name -password password

If you use the Windows service panel or the net stop command to stop the WAS processes and the service could not be stopped, update the existing Application Server service using additional stop arguments. You might need to end the server process from the Task Manager before updating the service. Use the -stopArgs and the-encodeParams parameters to update the service as described in the "Updating an existing Application Server service" example in the WASService command article.

After enabling single sign-on, I cannot logon to the administrative console

This problem occurs when single sign-on (SSO) is enabled, and you attempt to access the administrative console using the short name of the server, for example http://myserver:port_number/ibm/console. The server accepts your user ID and password, but returns you to the logon page instead of the administrative console.

To correct this problem, use the fully qualified host name of the server, for example http://myserver.mynetwork.mycompany.com:9060/ibm/console.

The following exception displays in the SystemOut.log file after I start the server and enable security: "SECJ0306E: No received or invocation credential exists on the thread."

The following message displays when one or more nodes within the cell was not synchronized during configuration:

SECJ0306E: No received or invocation credential exists on the thread. The Role based authorization check will not have an accessId of the caller to check. The parameters
are: access check method getServerConfig on resource FileTransferServer and module
FileTransferServer. The stack trace is java.lang.Exception: Invocation and received
credentials are both null.

Make sure that each of the nodes are synchronized and then restart the dmgr.

A Name NotFoundException error occurs when initially connecting to the federated repositories.

When the server attempts an indirect lookup on the java:comp/env/ds/wimDS name and makes its initial EJB connection to the federated repositories, the following error message displays in the SystemOut.log file:

NMSV0612W: A NameNotFound Exception

The NameNotFoundException error is caused by the reference binding definition for the jdbc/wimDS Java Naming and Directory interface (JNDI) name in the ibm-ejb-jar-bnd.xmi file. We can ignore this warning message. The message does not display when the wimDS database repository is configured.

For IBM extension and binding files, the .xmi or .xml file name extension is different depending on whether you are using a pre-Java EE 5 application or module or a Java EE 5 or later application or module. An IBM extension or binding file is named ibm-*-ext.xmi or ibm-*-bnd.xmi where * is the type of extension or binding file such as app, application, ejb-jar, or web. The following conditions apply:

• For an application or module that uses a Java EE version prior to version 5, the file extension must be .xmi.

• For an application or module that uses Java EE 5 or later, the file extension must be .xml. If .xmi files are included with the application or module, the product ignores the .xmi files.

However, a Java EE 5 or later module can exist within an application that includes pre-Java EE 5 files and uses the .xmi file name extension.

The ibm-webservices-ext.xmi, ibm-webservices-bnd.xmi, ibm-webservicesclient-bnd.xmi, ibm-webservicesclient-ext.xmi, and ibm-portlet-ext.xmi files continue to use the .xmi file extensions.
