php - Connect to ldap through coldfusion -

i trying connect ldap server using below coldfusion code. 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 parameters used in above cfldap tag correct or need add other parameters? issue relate ssl certificate? idea should use in "start"?

i have connected ldap using php using same parameter values same values when used throwing error in coldfusion? please suggest.
