Error description

  • This issue is seen in very limited scenario.
    
    Following steps illustrate how to reproduce the issue.
    
    1. Create a secure WebSphere profile using the advanced
    profile creation. On the page that says "Security Certificate
    (Part 2)" change the distinguished names from something like:
    
    cn=ABCDEFG.torolab.ibm.com,ou=ABCDEFGNode41Cell,ou=ABCDEFGNode41
    ,o=IBM,c=US
    and
    cn=ABCDEFG.torolab.ibm.com,ou=Root
    Certificate,ou=ABCDEFGNode41Cell,ou=ABCDEFGNode41,o=IBM,c=US
    
    To
    
    cn=ibmvmwinxpX.canlab.ibm.com,ou=ABCDEFGNode41Cell,ou=ABCDEFGNod
    e41,o=IBM,c=US
    and
    cn=ibmvmwinxpX.canlab.ibm.com,ou=Root
    Certificate,ou=ABCDEFGNode41Cell,ou=ABCDEFGNode41,o=IBM,c=US
    
    Basically the # of characters of "cn=_____" should equal 29.
    WebSphere will do a truncation if the name is > 32 characters.
    It will truncate to 31 characters. The result is something
    like this: "cn=ibmvmwinxpX.canlab.ibm.com, ".
    The trailing space is causing an issue.
    
    2. Start the server with the created profile using SOAP
    connection, the certificate will be added successfully into
    the trust store.
    
    3. Create another profile and follow the steps from 1
    
    4. Start the server with the created profile using SOAP
    connection, the chaining error will now occur:
    
    CWPKI0040I: An SSL handshake failure occurred from a secure
    client.  The server's SSL signer has to be added to the
    client's trust store.  A retrieveSigners utility is provided
    to download signers from the server but requires
    administrative permission.  Check with your administrator to
    have this utility run to setup the secure environment before
    running the client.  Alternatively, the
    com.ibm.ssl.enableSignerExchangePrompt can be enabled in
    ssl.client.props for "DefaultSSLSettings" in order to allow
    acceptance of the signer during the connection attempt.
    
    CWPKI0308I: Adding signer alias
    "CN=ibmvmwinxpX.canlab.ibm.com, " to local
               keystore "null" with the following SHA digest:
    
    31:4C:DC:F4:E6:10:20:C7:E1:64:0A:4A:0D:33:06:76:CD:9D:23:65.

    *                      caused by certificate that has          *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When two certificates with the same name were added added and
    if one had trailing space, WebSphere Application Server did not
    handle the trailing space properly.
