create-auth-realm

adds the named authentication realm

Synopsis

asadmin [asadmin-options] create-auth-realm [--help]
--classname realm_class [--property(name=value)[:name=value]*]
[--target target_name] auth_realm_name

Description

The create-auth-realm subcommand adds the named authentication realm.

This subcommand is supported in remote mode only.

Options

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin(1M) help page.

--help

-?

Displays the help text for the subcommand.

--target

Specifies the target on which you are creating the realm. Valid values are

server: Creates the realm on the default server instance. This is the default value.
configuration_name: Creates the realm in the specified configuration.
cluster_name: Creates the realm on all server instances in the specified cluster.
instance_name: Creates the realm on a specified server instance.

--classname

Java class which implements this realm. These include com.sun.enterprise.security.auth.realm.file.FileRealm, com.sun.enterprise.security.auth.realm.certificate.CertificateRealm, com.sun.enterprise.security.auth.realm.jdbc.JDBCRealm, com.sun.enterprise.security.auth.realm.ldap.LDAPRealm, com.sun.enterprise.security.auth.realm.ldap.PamRealm, and com.sun.enterprise.security.auth.realm.solaris.SolarisRealm, or a custom realm.

--property

Optional attribute name-value pairs for configuring the authentication realm. Authentication realms require provider-specific properties, which vary based on implementation.
The following properties are common to all of the supported realms, which include FileRealm, CertificateRealm, JDBCRealm, LDAPRealm, PamRealm, and SolarisRealm.

jaas-context

Specifies the Java Authentication and Authorization Service (JAAS) context.

assign-groups

(Optional) If this property is set, its value is taken to be a comma-separated list of group names. All clients who present valid certificates are assigned membership to these groups for the purposes of authorization decisions in the web and EJB containers.
Specific to each realm, you can specify the following properties.

You can specify the following properties for FileRealm:

file

Specifies the file that stores user names, passwords, and group names. The default is domain-dir`/config/keyfile`.

You can specify the following properties for CertificateRealm:

LoginModule

Specifies the name of a JAAS LoginModule to use for performing authentication. To use a JAAS LoginModule, you must first create an implementation of the javax.security.auth.spi.LoginModule interface, and then plug the module into a jaas-context. For more information, see "Custom Authentication of Client Certificate in SSL Mutual Authentication" in GlassFish Server Open Source Edition Security Guide.

You can specify the following properties for JDBCRealm:

datasource-jndi

Specifies the jndi-name of the jdbc-resource for the database.

user-table

Specifies the name of the user table in the database.

user-name-column

Specifies the name of the user name column in the database’s user table.

password-column

Specifies the name of the password column in the database’s user table.

group-table

Specifies the name of the group table in the database.

group-table

Specify the group table for an authentication realm of class JDBCRealm.

group-name-column

Specifies the name of the group name column in the database’s group table.

db-user

(Optional) Allows you to specify the database user name in the realm instead of the jdbc-connection-pool. This prevents other applications from looking up the database, getting a connection, and browsing the user table. By default, the jdbc-connection-pool configuration is used.

db-password

(Optional) Allows you to specify the database password in the realm instead of the jdbc-connection-pool. This prevents other applications from looking up the database, getting a connection, and browsing the user table. By default, the jdbc-connection-pool configuration is used.

group-table

Specifies the name of the group table in the database.

digest-algorithm

(Optional) Specifies the digest algorithm. The default is SHA-256. You can use any algorithm supported in the JDK, or none.

Note:

In versions of \{product---name} prior to 5.0, the default algorithm was MD5. If you have applications that depend on the MD5 algorithm, you can override the default SHA-25 algorithm by using the asadmin set subcommand:

asadmin> set server.security-service.property.default-digest-algorithm=MD5

You can use the asadmin get subcommand to determine what algorithm is currently being used:

asadmin> get server.security-service.property.default-digest-algorithm

Also note that, to maintain backward compatibility, if an upgrade is performed from \{product---name} v2.x or v3.0.x to \{product---name} 5.0, the default algorithm is automatically set to MD5 in cases where the digest algorithm had not been explicitly set in the older \{product---name} version.

digestrealm-password-enc-algorithm: (Optional) Specifies the algorithm for encrypting passwords stored in the database.

Note:

It is a security risk not to specify a password encryption algorithm.

encoding

(Optional) Specifies the encoding. Allowed values are Hex and Base64. If digest-algorithm is specified, the default is Hex. If digest-algorithm is not specified, by default no encoding is specified.

charset

(Optional) Specifies the charset for the digest algorithm.

You can specify the following properties for LDAPRealm:

directory

Specifies the LDAP URL to your server.

base-dn

Specifies the LDAP base DN for the location of user data. This base DN can be at any level above the user data, since a tree scope search is performed. The smaller the search tree, the better the performance.

search-filter

(Optional) Specifies the search filter to use to find the user. The default is uid=%s (%s expands to the subject name).

group-base-dn

(Optional) Specifies the base DN for the location of groups data. By default, it is same as the base-dn, but it can be tuned, if necessary.

group-search-filter

(Optional) Specifies the search filter to find group memberships for the user. The default is uniquemember=%d (%d expands to the user elementDN).

group-target

(Optional) Specifies the LDAP attribute name that contains group name entries. The default is CN.

search-bind-dn

(Optional) Specifies an optional DN used to authenticate to the directory for performing the search-filter lookup. Only required for directories that do not allow anonymous search.

search-bind-password

(Optional) Specifies the LDAP password for the DN given in search-bind-dn.

Operands

auth_realm_name: A short name for the realm. This name is used to refer to the realm from, for example, web.xml.

Examples

Example 1 Creating a New Authentication Realm

This example creates a new file realm.

asadmin> create-auth-realm
--classname com.sun.enterprise.security.auth.realm.file.FileRealm
--property file=${com.sun.aas.instanceRoot}/config/
admin-keyfile:jaas-context=fileRealm file
Command create-auth-realm executed successfully

Where file is the authentication realm created.

Exit Status

0: subcommand executed successfully
1: error in executing the subcommand
