LDAP Tools - Where are they? 350

Posted by Cliff from the an-empty-toolbox-is-useless dept.
fixe asks: "I have spent the last few months up to my eyeballs in LDAP. While I am still hopeful of what LDAP can bring to the table I am admittedly disappointed in the tools, support and documentation surrounding the standard. I have been successful at creating and populating an LDAP directory and even authenticating against it, however I cannot find decent replacements for useradd, userdel, usermod, passwd, etc. Nor have I found any decent LDAP editors or browsers (preferably console or web-based). I am hoping that the Slashdot crowd might be able to shed some light on the subject. Are there any LDAP veterans out there who can reccommend any tools? What is the best way to maintain system account synchronization with an LDAP directory? Or perhaps, is there a more attractive alternative to LDAP?"

    I know I'll get flamed like hell for writing this, but I suggest that you check out Microsoft's LDAP tools. I'm not sure about their interoperability with slapd etc, but they play along amazingly with Microsoft LDAP server.

    Also, check out gq , which is a pretty nice GTK+ based LDAP client. It's still very barebone, but it's better than the commandline tools for a lot of tasks.

    Unfortunatly, the best LDAP browser/editor I've found so far is neither web- nor console-based, but is a Windows program. LDAPBrowser 2.0, from the nice folks at Softerra [ldapadministrator.com], has been invaluable in helping me figure out how to make a bunch of openldap-based client programs talk to an MS Active Directory LDAP server. It's free-as-in-beer, and they have a number of other cool ldap toys available as well.

    You would think that wrapping a gtk+ interface around ldapsearch would be a straightforward and no-brainer proposition, but you would apparently be wrong.

    As far as account creation tools, there's some nice trends among the big user provisioning corporate grade systems (i.e. Access360) to manage accounts in LDAP.

    I'd stay away from Active Directory since it doesn't follow all of the standards. eDirectory's only big annoyance is that it's LDAP is actually a mapping on top of their old stuff, so sometimes that adds complexity. But for a long time they had the only multi-mastered replication setup. iPlanent now has that and MS/AD kinda does (but they have crappy granularity on their objects in case of collisions).

    I dont know about commercial LDAP offers, but openldap led me to the conclusion to NOT use ldap anywhere. I still have it installed in three locations and am actively working in porting it to mysql or unix flatfiles, because it's so unreliable. nss library from padl.com for some reason doesnt always closes its connections, so you hit 1024 file descriptors limit within a week or so. yes, you can compile with -DFD_SETSIZE, but this only gives you more time until restart is needed. Second, replication never worked reliably, so trying to avoid fd problem with more replicas only casued more pain and sleepless nights rebuilding and reindexing databases (125k user entries, it takes 7 hours on 4way xeon). And if only the slapd itself would work! It stops responding every now and then, for no reason. OK, i can catch these with a trivial script ... but recently, i got more and more examples where connection is accepted, but result never comes ... so ldapsearch just sits there without answer, huh. I've also seen examples where some slapd threads would occupy one or more cpu in the box, slowing things down noticeably.

    So, whatever you do, AVOID OpenLDAP.

    Directory Administrator [open-it.org] is a GUI (GTK+) frontend for user administration within a LDAP directory. It still requires some knowledge about a LDAP hierarchy, but it helps a lot.

    My advice is to create two user hierarchies: one for administrative non-human accounts (e. g. root, mail, www) and one for real users. Same thing for groups. This way you can manage your real-user accounts with some kind of GUI frontend and even re-use the objects in an addressbook like Evolution Contacts without risking a security hole.

    I am with a admin group trying to integrate a couple hundred UNIX and Windows machines into a single login using an Active Directory server, which provides us with Kerberos authentication, and an LDAP directory. (This was mandated to us "from above") The kerberos authentication of course was easy, however there is hardly ANY information about actually using LDAP in a production environment.. we are trying to use the active directory LDAP server to provide the POSIX gecos and home directory information for the UNIX clients... however the default Active Directory schema does not include RFC2307 [faqs.org]

    Probably the most frustrating part is if you go on google and look for help, you see people mentioning that this works, but never any specifics. I assume you are just using pam_ldap to grab a password crypt from an LDAP server (which is a secure as giving everyone read permissions on your shadow file).

    I think the best solution is to use an LDAP server to host all the user information that is normally in /etc/passwd. This is possible in Linux and Solaris using the nss_ldap module which lets you add an "ldap" entry to your network switch file, and use ldap instead of /etc/passwd. It seems the best solution is Kerberos for authentication and LDAP for everything else, which Active Directory can provide, in a mixed-OS environment even.. but has anyone been able to successfully run nss_ldap [padl.com] against an AD LDAP server? (without using services for UNIX or other kludges) LDAP seems to be an integration nirvanna.. but without proper documentation I am afraid it will never see broader use..

This has permitted us the option of "piggy-backing" any other web servers into this authentication scheme. The tools I have used have all been written by myself in Perl, using the Net::LDAP module. I believe there is at least one other module available to use, either available from CPAN. I believe Graham Barr is the author of this module. Using this approach, you should be able to build your own custom webpages for selective browsing of LDAP shares, and management.

    That's right you can do all this and a whole lot more, using Novell Netware.

It runs on almost any platform, available today. It even has additional modules that allow things like single signon and more. That's right, all the advantages of .NET without the bugs and security risks. And, the best part, is it has been shipping for quite a while now, unlike certain other vaporware products.

    • Novell's ConsoleOne is probably the best thing on the market today, although iPlanet has some very good stuff, too. Actually, Microsoft's ActiveDirectory is quite a nice directory, but of course, poisoned in such a way as to pretty much ensure that if you use it at all, your master servers will be AD, and all your administration will have to be done from AD, preventing you from using open standards effectively and marginalizing truly open systems. (This is "embrace and extend" at its sleaziest.)

      Also, don't forget the metadirectory approach as a valid one for trying to manage LDAP and other directories: Ganymede is the only open source project in this space that's much good, and it's starting to look fairly capable.

      Still, you get what you pay for: If you're making directory services a core part of your IT strategy (not a bad idea, but realize there are other approaches now, with Java, XML, etc.), it's worth buying the real stuff from Novell or iPlanet. Unfortunately, there's been little open source work in this area: if the open source products work at all (many don't), they don't scale and lack important features.

      That's too bad, because tying together things like MSWallet, .NET, and AD is one powerful way MS is going to continue to shove competitors off into the ditch. (...and a big reason why I and many others think the .GNU project is a BAD idea. Never play to your enemies strength.)

    I've been working with LDAP for the past four years as a manager, consultant, administrator, project manager and architect in various situations and for various companies and clients. My experience has been with Netscape/iPlanet, OpenLDAP and Active Directory. I've worked on very small and very large projects. LDAP has the potential to bring amazing efficiency gains to an enterprise or Internet-based organization (ISP or ASP), but it also is fairly immature.

    Let me rephrase that: the protocol is mature and useful, and the servers by and large are mature and useful, but the support tools stink, as a general rule. Since it sounds like you are mostly concerned with user administration, I will stick to just that, and let other people mention tools they've found useful.

    If you are using Solaris, AIX or Macintosh, using LDAP for accounts is pretty trivial, since the OS supports it directly - you'll need to have the POSIX user schema loaded, and point the OS's naming service to LDAP instead of its local database. Win2K/XP kind of force you to use Active Directory, so you are also taken care of there. In all of these cases, accounts other than the system superuser will be in LDAP, and so therefore synchronization is not a problem.

    useradd, userdel, usermod and passwd are all replaced by ldapmodify, or you can use the tools included with some servers (the iPlanet console being a good example of how to do this right). Right now, there doesn't seem to be any substitute for thoroughly learning ldapsearch and ldapmodify, Perl and Net::LDAP. You can use ldapsearch and ldapmodify for quick actions (adding, modifying or deleting a single user, or changing a password) and Perl and Net::LDAP for more complex operations (or for putting together a CGI for common functions like changing a user's password).

    I find I end up writing built-to-purpose Perl tools just about everywhere I go. In some cases, this is because of differences in admin policy at different sites, or differences in schema. In others, the issue is more contractual (whomever is paying me gets ownership of the code I write, so I have to rewrite from a clean sheet at the next site).

    The good news is, it is fairly quick and painless to write replacements for useradd, usermod, userdel and passwd which can be run from the command line or as a CGI, and you only have to write them once for your site, if you write them well in the first place.

    4 - You can assemble a whole range of ISP services (mail, ftp, http, whatever) based on an LDAP tree. Even if you can't find a _insert favorite daemon here_ supporting LDAP, you can always use...

    5 - PAM/NSS LDAP. It just rocks. If you configure it properly, anything using PAM/NSS will use/update your tree accordingly. This includes unix tools like "passwd", "useradd", or "finger", or services like QPopper and OpenSSH.

    6 - The best way to automate some processes is to create our own tools. Net::LDAP is very easy to use, and does anything you can think of (in terms of LDAP ops)

  • I keep hearing all of these announcements about LDAP-generic tools, but I don't think anybody is answering his questions. He's talking about USER-SPECIFIC tools, which is rather lacking. Granted, there are many different schemas for users, but it's more or less only a couple of standard schemas (that come with OpenLDAP).

    There's not that many good user management tools for LDAP. I don't feel like typing it in on raw mode with GQ, when a lot of it is duplicate information (to make sure it gets caught with the different schema names).
  • As the host of open-it.org, are entire focus is solving this problem. Many people are actively working on integration with ActiveDirectory, and other tie ins, and people loosely associated with Open-IT are working in various projects that help resolve this (Samba-TNG supports ldap backends).

    As for management, we now host Directory Administrator,a great GTK front end to user management, I have also created a simply useradd program for creating users in ldap (its called addluser).

    We are currently working on a new release of Directory Administrator with a new backend which will allow CLI, GUI, and Web clients to be built on it. Further, if you love WebObjects, Apple just released 5.1, which has a JNDI adaptor, allowing quick Web Apps to be built against LDAP directory servers using Java.

    Is the documentation not up to snuff at Open-IT, then help out! We have some basic howtos, and I package pam_ldap, nss_ldap, openldap, and other great things to get you going.

    Back to work...
    • Checked out Directory Administrator. My biggest beef with it is that it seems to be hardcoded to manage posixUser and posixGroup objects, which we don't use at all. So it looks pretty but doesn't let me Administrate my Directory, as the title would suggest :)

  • Ganymede, an LDAP manager / alternative (Score:5, Informative)

    Well, I'll post a pointer to Ganymede [utexas.edu], which is not specifically for LDAP, but which could probably be useful in a lot of environments.

    Ganymede is at once simpler than LDAP, in that it doesn't support the kind of hierarchical objects that LDAP and x.500 support, and in that it doesn't actually speak LDAP, and more complex, in that it has a sophisticated transactions model and can handle complex concurrent operations while maintaining namespace and referential integrity.

    Ganymede is useful if you want to have a smallish (less than 50,000 users, say) 'flat' directory, but for which you want to allow detailed permisison delegation and fine-grained concurrency. If you have a very large NIS domain and you want to allow scores of users and admins to be changing their passwords and account information concurrently, Ganymede will work wonders for you.

    We actually use Ganymede for just about everything here, up to and including our DNS, although we don't have our DNS support code 'productized' yet. We do master our LDAP directory from Ganymede data, in order to support applications which can use an LDAP server for an address book (such as Outlook and Netscape Messenger). If you were to combine Ganymede with something like Thomas Reith's ldapdiff [rhoen.de] utility, you could combine Ganymede's sophisticated administration services with LDAP for distribution.

    Softerra's LDAP Administrator [ldapadministrator.com] is pretty good, and they have a freeware version called LDAP Browser. The LDAP Browser/Editor [iit.edu] is nice also.

    If you are using LDAP as your addressbook, ldap-abook [freshmeat.net] is a nice interface to add/delete/modify entries. Most email clients are LDAP-aware these days and it's convenient to be able to share an address book between my personal and work email accounts.

    I've had to roll my own to do system accounts, however. Make ldapmodify your new best friend, or write an interface of your own - there is a lot of support for Perl or PHP LDAP functions out there. Server-side, I've used OpenLDAP [openldap.org] and iPlanet's Directory Server [iplanet.com], and I prefer iPlanet. iPlanet has a free non-commercial license option, is significantly faster than OpenLDAP, and has hooks to synchronize with an NT or Active Directory domain so you could do all the user administration in Windows and they would propagate over to your LDAP server.

    Other fun things you can do with LDAP are:

    Handle Unix authentication through pam_ldap [padl.com]
    Hook into NIS with the NIS/LDAP gateway [padl.com]
    Authenticate through apache with mod_auth_ldap [nona.net] or auth_ldap [rudedog.org] or Netegrity [netegrity.com]
    Centralize your smtp routing data in LDAP for sendmail

    Good luck.
  • Also, you might check out iDSRK from iPlanet. It's a set of performance testing tools, a tool for generating bulk loads, etc. Quite useful in some circumstances.

  • A quick plug for a useful LDAP-related tool I wrote: it's an LDAP to DSML (version 1.0) gateway, which allows you to read DSML (which is an XML-based language) out of, and write it to, any LDAP-enabled directory server.

    It's not graphical, though :-)

    Find it here [dsmltools.org].

  • JDBC driver for LDAP (Score:2, Interesting)

    by eGuy ( 545520 )
    Novell has a JDBC driver for LDAP. It maps SQL statements to LDAP(At least those it can. Those it can't map directly to LDAP it does it's own joining of the data). Its a free download available at developer.novell.com/ndk/ldapjdbc.htm Its also 'works with LDAP 2000' certified. (From the OpenGroup) This means it should work with any LDAP compliant directory. Its useful if you have normal reporting tools that use JDBC drivers. For example StarOffice can import data from JDBC drivers with a nice GUI - This way you don't have to know about the LDAP syntaxes or anything about LDAP except that its a Data Base. They also have an ODBC driver that only works with eDirectory(NDS). Hope that helps.
  • LDAP is a large part of my job, I've written dozens of scripts for handling various LDAP chores. And whatever you do I strongly recommend that as much as possible for any scripting, use something like Net::LDAP instead of using or wraping shell scripts around any of the OpenLDAP utils. Maybe it's just a project maturity thing or something, but the OpenLDAP people seem to have an infuriating habit of changing the behaviour/output of ldapsearch which means you will end up having to tweak or rewrite every script that uses it if you ever upgrade. That said the OpenLDAP utils are quite handy to have around, no matter which implementation you're running as your actual LDAP servers.

    Also if you're running iPlanet/Netscape's directory server grab their resource kit, the ilash util which can do a lot of things, has a really nice feature in that you can drop an entry into vi and edit it. ud or whatever it's called in the OpenLDAP utils can sort of do that, but only for certain hardcoded attributes, and not the ones you're likely to need either.
