Class: Strategy

Strategy constructor
The LDAP authentication strategy authenticates requests based on the credentials submitted through an HTML-based login form.
Applications may supply a `verify` callback which accepts `user` object and then calls the `done` callback supplying a `user`, which should be set to `false` if user is not allowed to authenticate. If an exception occured, `err` should be set.
Options can be also given as function that accepts a callback end calls it with error and options arguments. Notice that the callback is executed on every authenticate call.
Example:

var LdapStrategy = require('passport-ldapauth').Strategy;
passport.use(new LdapStrategy({
    server: {
      url: 'ldap://localhost:389',
      bindDN: 'cn=root',
      bindCredentials: 'secret',
      searchBase: 'ou=passport-ldapauth',
      searchFilter: '(uid={{username}})',
      reconnect: true
    }
  },
  function(user, done) {
    return cb(null, user);
  }
));
