Step Step 5 of 11: Create the Host Credential Mapper database

The Host Credential Mapper (HCM) (opens new browser) is one of the key players in the Web Express Logon process because it maps users' network IDs to their host IDs. Since the DCAS parameters supplied with Web Express Logon are designed to work with a JDBC database, the administrator in this scenario uses IBM DB2 to configure the HCM database. Using this type of network-accessible database provides a flexible and secure means of associating users' network IDs with their host IDs.

Using DB2, the administrator creates a table with column headings that correspond to the DCAS parameters that he will add to the servlet configuration file in the next step. The following four column headings are in all upper case and must exactly match the parameter values he will specify in the servlet configuration file:
