通过coldfusion连接到ldap

I am trying to connect to LDAP server using below Coldfusion code. But I get an error "Authentication failed:[LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903C9, comment: AcceptSecurityContext error, data 52e, v23f0 ]"

<cfldap  
    action = "Query" 
    server = "xxxx.edu" 
    attributes = "*" 
    name = "result" 
    password = "yyy" 
    port = "000" 
    start = "cn=xxx,ou=xxx,dc=xx,dc=xx,dc=edu" 
    username = "xxx">

Are the parameters used in the above cfldap tag are correct or do I need to add any other parameters? Does this issue relate to SSL certificate? Any idea what should I use in "start"?

I have successfully connected to LDAP using php using the same parameter values but the same values when used are throwing an error in Coldfusion? Please suggest.

Thanks in Advance
