The following realms are supported in the Enterprise Server:
file – Stores user information in a file. This is
the default realm when you first install the Enterprise Server.
ldap – Stores user information in an LDAP directory.
Stores user information in a database.
In the JDBC realm,
the server gets user credentials from a database. The Application
Server uses the database information and the enabled JDBC realm option
in the configuration file.
For digest authentication,
a JDBC realm should be created with jdbcDigestRealm as
the JAAS context. The realm must be referenced in a realm-name element
in the web.xml file
as is standard practice.
certificate – Sets up the user
identity in the Enterprise Server security context, and populates it with
user data obtained from cryptographically verified client certificates.
solaris – Allows authentication using Solaris username+password data. This realm is only supported on the Solaris operating
system, version 9 and above.
