Example 26 with CompareRequest

use of org.apache.directory.api.ldap.model.message.CompareRequest in project directory-fortress-core by apache.

the class LdapDataProvider method compareNode.

/**
 * This method uses the compare ldap func to assert audit record into the directory server's configured audit
 * logger.
 *
 * This is for one reason - to force the ldap server to maintain an audit trail on checkAccess api.
 *
 * Use proxy authz control (RFC4370) to assert the caller's id onto the record.
 *
 * @param connection is LdapConnection object used for all communication with host.
 * @param dn         contains address of distinguished name to begin ldap search
 * @param userDn     dn for user node
 * @param attribute  attribute used for compare
 * @return true if compare operation succeeds
 * @throws LdapException                thrown in the event of error in ldap client or server code.
 * @throws UnsupportedEncodingException in the event the server cannot perform the operation.
