使用示例：
<subsystem xmlns="urn:wildfly:elytron:1.0" final-providers="combined-providers" disallowed-providers="OracleUcrypto">
...
<security-realms>
...
<ldap-realm name="ldap-realm" dir-context="ldap-connection" direct-verification="true">
<identity-mapping rdn-identifier="uid" search-base-dn="ou=users,dc=group-to-principal,dc=wildfly,dc=org">
<attribute-mapping>
<attribute from="uid" to="Roles" filter="(uniqueMember={1})" filter-base-dn="ou=groups,dc=group-to-principal,dc=wildfly,dc=org"/>
</attribute-mapping>
</identity-mapping>
</ldap-realm>
</security-realms>
...
<dir-contexts>
<dir-context name="ldap-connection" url="ldap://localhost:10389" principal="uid=admin,ou=system">
<credential-reference clear-text="secret"/>
</dir-context>
</dir-contexts>
</subsystem>

- 更新 -
参考 ldap.xml 来设置 LDAP 以进行测试，这可能很有用。
