I installed ldap client and software on two ubuntu machines. but when i try to log in with the phpldapadmin gui it displays

Network Error (tcp_error)

A communication error occurred: "Connection refused"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

i am new to ldap and i cudnt really find a forum or thread which was talking about this problem.

hope someone can help me
