["Donny George" <donny008@gmail.com>]

hello all

i am a beginner with openldap and installed a server and a client with ldap(both machines ubuntu 8.04)

but once i tried to populate the database at the server it gave the error that it couldnt contact the server. i cudnt connect to the server frmo the client either. 

i ran the command ldapsearch -d 255 to debug and heres the result 

ldap_create
ldap_pvt_sasl_getmech
ldap_search
put_filter: "(objectclass=*)"
put_filter: simple
put_simple_filter: "objectclass=*"

ldap_pvt_connect: fd: 3 tm: -1 async: 0
ldap_close_socket: 3
ldap_err2string
ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1)


and if i run ldapsearch -x it gives the message

ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
