ldapjs makes the LDAP protocol a first class citizen in Node.js. ## Usage For full docs, head on over to . var ldap = require('ldapjs'); var server = ldap.createServer(); server.search('dc=example', function(req, res, next) { var obj = { dn: req.dn.toString(), attributes: { objectclass: ['organization', 'top'], o: 'example' } }; if (req.filter.matches(obj.attributes)) res.send(obj); res.end(); }); server.listen(1389, function() { console.log('ldapjs listening at ' + server.url); }); To run that, assuming you've got the [OpenLDAP](http://www.openldap.org/) client on your system: ldapsearch -H ldap://localhost:1389 -x -b dc=example objectclass=* ## Installation npm install ldapjs ## Formatting objectGUID attribute value var ldap = require('ldapjs'); ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B; var client = ldap.createClient({ url: 'ldap://127.0.0.1/CN=test,OU=Development,DC=Home' }); var opts = { filter: '(objectclass=user)', scope: 'sub', attributes: ['objectGUID'] }; client.bind('username', 'password', function (err) { client.search('CN=test,OU=Development,DC=Home', opts, function (err, search) { search.on('searchEntry', function (entry) { var user = entry.object; console.log(user.objectGUID); }); }); }); _Note: for the sake of simplicity all checks and error handling was removed from the sample above._ The console output may be similar to the following (depending on the amount of users in the directory): {a7667bb1-4aee-48ce-9d9d-a1193550deba} {8d642ac8-14c6-4f27-ac5-94d39833da88} Available formatting modes: GUID_FORMAT_N N specifier, 32 digits: 00000000000000000000000000000000 GUID_FORMAT_D D specifier, 32 digits separated by hypens: 00000000-0000-0000-0000-000000000000 GUID_FORMAT_B B specifier, 32 digits separated by hyphens, enclosed in braces: {00000000-0000-0000-0000-000000000000} GUID_FORMAT_P P speficier, 32 digits separated by hyphens, enclosed in parentheses: (00000000-0000-0000-0000-000000000000) GUID_FORMAT_X X speficier, four hexadecimal values enclosed in braces, where the fourth value is a subset of eight hexadecimal values that is also enclosed in braces: {0x00000000,0x0000,0x0000,{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}} Guid formatting is unobtrusive by default. You should explicitly define formatting mode in order to enable it. ## License MIT. ## Bugs See .
