MIT. See "LICENSE" file.
var ADStrategy = require('passport-adauth');
passport.use(new ADStrategy({
server: {
url: 'ldaps://corp.example.com',
domainDn: 'dc=example,dc=com',
tlsOptions: {
ca: './domain-ca.cer'
}
}
}));
server
: LDAP settings. These are passed directly to adauth. See its documentation for all
available options.
url
: The LDAP URL for the domain controller e.g.
ldaps://corp.example.com:636
bindDn
: A user with just enough permissions to read other users'
attributes e.g. CN=LDAP User,OU=Users,OU=MyBusiness,DC=example,DC=com
bindCredentials
: Password for bindDnsearchBase
: The base suffix for all users to narrow results e.g.
OU=Users,OU=MyBusiness,DC=example,DC=com
searchAttributes
: Optional array of attributes to limit what attributes
are fetched from AD, e.g. ['displayName', 'mail']
. Defaults to
undefined
, i.e. fetch all attributestlsOptions

: Field name where the username is found, defaults to
usernamepasswordField
: Field name where the password is found, defaults to
passwordpassReqToCallback
: When true
, req
is the first argument to the verify
callback (default: false
):passport.use(new ADStrategy(..., function(req, user, done) {
...
done(null, user);
}
));
Note: you can pass a function instead of an object as options
, see the
example below
Use passport.authenticate()
, specifying the 'adauth'
strategy, to
authenticate requests.
authenticate()
optionsIn addition to default authentication options the following options are available
for passport.authenticate()
:
badRequestMessage
flash message for missing username/password (default:
'Missing credentials')invalidCredentials
flash message for InvalidCredentialsError
,
NoSuchObjectError
, and /no such user/i
LDAP errors (default: 'Invalid
username/password')userNotFound
flash message when AD returns no error but also no user
(default: 'Invalid username/password')constraintViolation
flash message when user account is locked (default:
'Exceeded password retry limit, account locked')var express = require('express'),
passport = require('passport'),
bodyParser = require('body-parser'),
ADStrategy = require('passport-adauth');
var adOptions = {
server: {
url: 'ldap://corp.example.com',
bindDn: 'CN=LDAP User,OU=Users,OU=MyBusiness,DC=example,DC=com',
bindCredentials: 'mypassword',
searchBase: 'OU=Users,OU=MyBusiness,DC=example,DC=com'
}
};
var app = express();
passport.use(new ADStrategy(adOptions));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(passport.initialize());
app.post('/login', passport.authenticate('adauth', { session: false }),
function(req, res) {
res.send({ status: 'ok' });
});
app.listen(8080);
Simple example config for connecting over ldaps://
to a server requiring some
internal CA certificate (often the case in corporations using Windows AD).
var opts = {
server: {
url: 'ldaps://corp.example.com:636',
bindDn: 'CN=LDAP User,OU=Users,OU=MyBusiness,DC=example,DC=com',
bindCredentials: 'mypassword',
searchBase: 'OU=Users,OU=MyBusiness,DC=example,DC=com'
tlsOptions: {
ca: './domain-ca.cer'
}
}
};
...
Instead of providing a static configuration object, you can pass a function as
options
that will take care of fetching the configuration. It will be called'
with the req
object and a callback function having the standard (err, result)
signature. Notice that the provided function will be called on every
authenticate request.
var getLDAPConfiguration = function(req, callback) {
// Fetching things from database or whatever
process.nextTick(function() {
var opts = {
server: {
url: 'ldap://corp.example.com',
bindDn: 'CN=LDAP User,OU=Users,OU=MyBusiness,DC=example,DC=com',
bindCredentials: 'mypassword',
searchBase: 'OU=Users,OU=MyBusiness,DC=example,DC=com'
}
};
callback(null, opts);
});
};
var ADStrategy = require('passport-adauth');
passport.use(new ADStrategy(getLDAPConfiguration,
function(user, done) {
...
return done(null, user);
}
));
