ldap connection in groovy script in soapui

Hi,
I am trying to create ldapuser through groovy script in soapui.
Below is the code, I have placed the groovy ldap jar also. But not successful.

package snippets.security.ldap.groovyldap.add
import org.apache.directory.groovyldap.LDAP
def ldap = LDAP.newInstance('ldap://148.147.35.152:389', 'cn=root,dc=Avaya', 'w00dstock')
assert ! ldap.exists('cn=Heather Nova,ou=xyz,dc=abc')
// define the attributes as a map
def attrs = [
dn: 'cn=Heather Nova,ou=xyz,dc=abc',
sn: 'Nova',
changetype: 'add',
givenName: 'Feather',
MailboxNumber: '98223',
]

ldap.add('cn=Heather Nova,ou=xyz,dc=abc', attrs)
assert ldap.exists('cn=Heather Nova,ou=xyz,dc=abc')


keep getting javax.naming,AuthunticationException, Ldap Error Code 38.
Any help regarning this is really appreciative.
