Note: Feb 8, 2000: The LDAP interface in the Control Panel has been removed temporarily to prevent confusion pending upgrades to Web Crossing LDAP service.

Introduction to LDAP

Lightweight Directory Access Protocol (LDAP) provides outside clients access to Web Crossing user directory information, such as usernames and email addresses.

WebCrossing can act as both an LDAP server and a client. Using these features, Web Crossing can provide directory information to standard LDAP search services and also allow authentication of users between two cooperating Web Crossing sites.

In many cases, you might find your needs for LDAP are better served by Web Crossing's support for the newer XML-RPC functionality, which supports remote procedure calls.

The LDAP Service Control Panel

You turn on LDAP in the Control Panel > LDAP service panel.

This control panel is divided into two sections: one section allows you to set up Web Crossing as an LDAP client, so that it accesses an LDAP server to retrieve information. The second section lets you set up Web Crossing as an LDAP server, providing information to incoming clients.

LDAP Client Settings

Figure 1 - LDAP Client Settings

The LDAP Client settings in figure 1 are as follows:

  • The Enable Lightweight Directory Access Protocol client service checkbox is the on/off switch that enables and disables Web Crossing LDAP client services.
  • The LDAP Remote Server Address is the address of a known LDAP server, which may be another Web Crossing server. You will need to turn on Web Crossing LDAP server services in the remote Web Crossing server.
  • The LDAP server port is the TCP/IP port used for making LDAP connections. The default port number is 389.
  • The LDAP server password is used if a password is required for accessing the remote server.
  • The LDAP Server DN is the distinguished name for the remote LDAP server. LDAP directory entries are part of a hierarchical names space, analogous to the DNS name space described in the Internet Concepts section. The entry here is a path to the data entry you want Web Crossing to find. In other words, the DN you provide gives Web Crossing a starting place from which to search.


LDAP Server Settings

Figure 2 - LDAP Server Settings

The LDAP Server Settings shown in figure 2 are as follows:

  • The Enable checkbox turns on an off LDAP serving for your Web Crossing server.
  • The LDAP port to listen on is the TCP/IP port for LDAP services. The default port number is 389.
  • The Maximum simultaneous connections value lets you limit the number of TCP/IP connections served by LDAP. This allows you to control load balancing for your system. If you have limited bandwidth, you might want to keep this number low to prevent excess LDAP requests from overwhelming your system.
  • The Inactive timeout setting value is the time at which Web Crossing will sever an LDAP serving connection if there is no response from the requesting side.


Troubleshooting

Lundeen & Associates are in the process of upgrading their implementation of LDAP. If you are experiencing difficulties, please keep in touch with new release information posted on the Web Crossing site's forum.
