C. Edit the CMS-related parameters.

In this step, you will edit two of the three INIT parameters in the web.xml file. INIT parameters adapt the servlet to your environment. You will not edit the CMPINetworkSecurity parameter name or value.

Locate the CMPICredentialMappers parameter and change the name of its current value (echo) to the name of the DCAS HCM plug-in—CMPIDCASPlugin:
```
<init-param>
  <param-name>CMPICredentialMappers</param-name> 
  <param-value>CMPIDCASPlugin</param-value> 
</init-param>
```

Locate the echo parameter and change the name of its current value (echo) to the name of the parameter value that you specified for the HCM plug-in—CMPIDCASPlugin.

Now, replace the parameter value with a compound value that contains the full class path name of the implementing class, the authentication type to be used by the DCAS HCM plug-in, and the host mask. Separate these values with commas. In this example, com.ibm.eNetwork.security.sso.cms.CMPIDCAS is the full class path name, AuthType_3270Host is the authentication type, and * is the host mask.

Full class path name

The CMS uses the value of the full class path name to create a class object of the specified type. That object is then used to handle CMS or HCM plug-in requests. The specified class file must be in the ...\WEB-INF\classes subdirectory in a loose file (not as a JAR file). From this location, the CMS will be able to access and use it whenever the need arises.

Authentication type

This value is used to identify the type of authentication that the requestor needs. Once you specify the desired authentication type, the CMS can better identify which credential mapper to select to handle the request. You can pair multiple authentication types together to give HCM plug-ins the freedom to support multiple authentication types. Use the vertical bar character to join multiple authentication types.

The five identified authentication types are listed in the Table 1:

Authentication used in Secure Shell (SSH) on VT emulation or sftp sessions are not supported by the HCM plug-in.

Table 1. Authentication types and descriptions
Authentication type	Description
`AuthType_3270Host`	Identifies the credentials to be used with a 3270 emulation
`AuthType_5250Host`	Identifies the credentials to be used with 5250 emulation
`AuthType_VTHost`	Identifies the credentials to be used with VT emulation
`AuthType_FTPPassword`	Credentials used to access an FTP host
`AuthType_ConfigServer`	Credentials identified by the token used to identify the user to the Z and I Emulator for Web configuration server (if you are using the Configuration server-based model
`AuthType_All`	Identifies the credentials to be used for all authentication types

Host mask

The host mask is a secondary selection criteria used by the CMS to identify the most appropriate credential mapper. This value can contain one or more host addresses. Use the vertical bar character to join multiple addresses. Use the asterisks character to wildcard a host address. The wildcard character may start, end, or start and end a host address.

Table 2 lists valid wild-carded addresses:

Table 2. Host masks and values matched
Host mask	Value matched
`*.raleigh.hcl.com`	Matches all addresses that end with `.raleigh.hcl.com`
`ralvm*`	Matches all addresses that start with `ralvm`
`*`	Matches all
`xyz`	Matches any host address that contains `xyz`

Code example:

<init-param>
  <param-name>CMPIDCASPlugin</param-name> 
  <param-value>com.ibm.eNetwork.security.sso.cms.CMPIDCAS, 
		AuthType_3270Host, *</param-value> 
  </init-param>
