Username and Password
This guide scenario will create an authenticator that uses username & password against a user store (commonly via LDAP or JDBC).
Alias
Here you enter an alias for your authenticator, which is a more user friendly version of the authenticator's ID (which is a random, auto generated UUID string).
User store
Here you configure which user store the authentication should be performed against. You may select an existing user store, or configure a new one. For instructions on configuring a new one, see the guide scenario for "Connections - LDAP" or "Connections - JDBC".
Search settings
Depending on whether your connection is LDAP or JDBC, your next step will look different. For LDAP, you enter your search filter such that the username that the user will enter on the web correlates with your userid-attribute in the directory. You also select the search base for the users by clicking "choose" and selecting the correct category for your users.
For JDBC you simply adjust the SQL query so that it will select the correct user.
