LDAP is a protocol for searching for email addresses and checking the passwords of people with a Unix ID. The College runs three LDAP servers:

  • nds1.williams.edu is the Novell NetWare server that has a lot of information about you, and that can check your password;
  • nds2.williams.edu is nds1's twin;
  • ldap.williams.edu is used solely for searching email addresses.

Auto-completing email addresses

Many email clients let you configure an LDAP server to act as your address book. Here are the settings you'll need:

Server: ldap.williams.edu

Search Base: ou=People,o=williams

Port: 389

Use SSL: No

Authenticating with LDAP

Here are settings for authenticating different types of users. Ideally, you can authenticate more than one type, but that will depend what kind of support your software has. Of course, if you are a true badass, you shouldn't be afraid to write your own extension to handle multiple LDAP settings. In all cases, you need to somehow substitute $USER with the name of the user that's logging in.
