Web server plug-in default configuration in SSL

When you create a new web server definition, WAS associates the web server plug-in with a Certificate Management Services (CMS) keystore for a specific node. The keystore contains all of the signers for the current cell with the self-signed or chained certificate, which belongs to the node. The plug-in can communicate securely to WAS, even when the plug-in is configured with SSL client authentication enabled.

When you set the web server definition to webserver1 on node Node01, WAS creates the keystore configuration. The keystore is scoped to the webserver1 server, which makes it visible to this server only. Other processes cannot use this keystore definition.

The following sample code from the security.xml file shows the configuration entries for the web server plug-in.

<keyStores xmi:id="KeyStore_1132357815719" name="CMSKeyStore"
password="{xor}HRYNFAtrbxEwOzpvbhw6MzM=" provider="IBMCMSProvider"
location="C:\WASX_e0540.11\AppServer\profiles\AppSrv01/config/cells
/Cell01/nodes/Node01/servers/webserver1/plugin-key.kdb"
type="CMSKS" fileBased="true" createStashFileForCMS="true"
managementScope="ManagementScope_1132357815718"/>
<managementScopes xmi:id="ManagementScope_1132357815718" scopeName="
(cell):Cell01:(node):Node01:(server):webserver1" scopeType="server"/> 

The following sample code shows how the CMS keystore and stash file are generated in the security.xml file.

C:\WebSphere\AppServer\profiles\Dmgr01\config\cells\Cell01\nodes
\Node01\servers\webserver1\plugin-key.kdb
C:\WebSphere\AppServer\profiles\Dmgr01\config\cells\Cell01
\nodes\Node01\servers\webserver1\plugin-key.sth

The default password for the keystore is WebAS. You can change the default keystore password by using either the administrative console or the appropriate AdminTask command. The following sample code shows the AdminTask command that you can use to create this CMS keystore.

$AdminTask createCMSKeyStore /config/cells/Cell01/nodes/Node01
/servers/webserver1/plugin-key.kdb myhost.austin.ibm.com

Note the following characteristics of the previous example:

• We can create only one CMSKeyStore entry for each management scope. If a CMS keystore already exists for scope (cell):Cell01:(node):Node01:(server):webserver1, then you cannot create another CMSKeyStore entry
• The Uniform Resource Identifier (URI) for the keystore name is /config/cells/Cell01/nodes/Node01/servers/webserver1/plugin-key.kdb
• The host name in the plug-in location is myhost.austin.ibm.com. WAS uses this name to create a chained certificate, if a chained certificate does not already exist for that particular node. If a chained certificate already exists for the node, then the certificate is put into the CMS keystore and all the signers from the cell are added, by default.

When additional nodes are federated, the signers for these nodes are not automatically added to each web server for the CMS keystore. For the web server plug-in to be able to communicate with a newly federated node, manually exchange signers with the CMSKeyStore keystore. Use the admin console keystore certificate management function to exchange signers. See Extract a signer certificate from a personal certificate.
