Host Credential Mapper (HCM)

The HCM is a back-end repository that maps users' network IDs to their host IDs. This repository can be a JDBC database such as IBM DB2. The DCAS and Vault plug-ins provided with Web Express Logon are designed to work with a such a database. Another possibility for a repository is an LDAP directory. However, using LDAP as your HCM requires you to write your own plug-in..
