Class LDAPUtils

  • @Supported
public final class LDAPUtils
extends Object
    Utility methods to help interaction with the OpenDJ LDAP SDK. There are two main ways currently to create connection pools/factories: In case the configuration provides the possibility to assign LDAP servers to OpenAM servers/sites, then either you can prioritize manually (if the logic differs from this implementation) and create the corresponding LDAPURL objects, or you can pass in the list to the newPrioritized* methods.
