[Fedora-directory-users] Schema Conversion
by D Canfield 26 Oct '05

26 Oct '05

I don't suppose anyone has found an easy way to convert OpenLDAP schema into fedora-ds compatible ldif files? We've got about 100 attributes defined, and I'm really not looking forward to entering them all by hand... Thanks DC

[Fedora-directory-users] Wishlist
by Jeff Clowser 25 Aug '05

25 Aug '05

I was looking at the wishlist (http://directory.fedora.redhat.com/wiki/Wishlist) Some of these things can already be done, and should be just a matter of configuration, based on it's Netscape DS heritage. Wanted to give back by suggesting some ideas on how to accomplish these wishes where no code changes are needed. Under Core Server Features: 1. Disable anonymous binds. By default, the server creates an annonymous aci in the suffix entry (i.e. top of the tree). If you edit that entry and remove that aci, you remove anonymous access. Note that some services "require" anonymous access, so may break (some clients/apps may need to do anon access to look up a uid to get a dn to bind as for auth, etc, so it may either be necessary to change the config of these clients to bind as something that can still do these lookups, or you may have to just tweak anonymous access to limit what it can see, rather than removing it altogether). 2. Option to control resource limits specifically for anonymous. Anonymous uses the default server settings for these resource limits. I believe Fedora-ds supports the following attributes on entries: nslookthroughlimit, nsizelimit, nstimelimit, and nsidletimeout (these are in the schema, and the Sun and Netscape servers fds is based on supports them). If you put these attributes in an entry, when that entry binds to the server, these resource limits are used instead of the server defaults. So, a way to implement control of resource limits for anonymous is to set the server default settings to whatever you want anonymous to have, and then to set these attributes on all users that you want to be different (i.e. have more lenient limits) than anonymous. For things like mail servers, etc, I always create an entry for the mail/whatever server, and set these attributes to appropriate values. FYI: setting any of these to -1 means unlimited. Under Console Features: 2. Add host based access control to posixAccount/shadowAccount to determine who can log into what hosts. While this is not specifically in Console, it's relatively straightforward to add this, if you're a little creative :) : - First, create a new ldap attribute in the schema - lets call it something like "allowedHosts". Make sure it is multivalued. - Second, you need to add it to an objectclass. You could add it to the PosixAccount objectclass (simpler, but not recommended because you are modifying a standard objectclass), or create a new objectclass (lets call if unixUser, make it derive from posixAccount, and add allowedHosts as a required attribute). - When you create users, set their objectclass to posixAccount and unixUser (and shadowAccount). Add a list of hostnames you want the user to log into in the allowedHosts field. - When you configure the Unix/Linux/etc box that the user will log into: . if you can define a filter for finding users, set it to "(&(objectclass=posixAccount)(allowedHosts=<hostname>))" replacing <hostname> with the hostname of the machine they are logging into. . If you cannot define a filter, you can set an IP based aci in the directory for each of these hosts that allows them to see only users that can log into "this" box. You may have to tweak other aci's, such as anonymous, so that they don't allow the box to see the users you don't want seen. One note to make: purists would say DON'T create attributes and objectclasses on the fly like this. Personally, I don't have a problem creating attributes/objectclasses for my own internal use. But... if someone wanted to formalize this with "real" registered oids for the attributes and objectclasses, and/or defining and going through all the paperwork/review process to do this or expand posixAccount officially, I would have no objections :). NDS/FDS/SDS are nice in that they allow you to create these local definitions without all the complexities of registering those definitions to the rest of the world. - Jeff

[Fedora-directory-users] schema extension via ldif at install time
by Brian K. Jones 20 Jul '05

20 Jul '05

Hi all, I want to perform a custom installation of FDS, and when it asks for the ldif file to be imported, I want to point it at a file that contains ldif to extend the schema, and add the entries dumped from my old openldap directory. Without extending the schema, the import will fail because every entry violates the default schema. However, turning schema checking off leaves some small chance that there is something in my directory that shouldn't be there or isn't as it should be. I have another installation of FDS on a test machine, and I used the GUI to add my extra objects and attributes, and I tried copying the resulting ldif to the server I'm now trying to install (minus operational stuff), but the install ignored the cn=schema part of my LDIF file (the part holding the schema extensions), and subsequently, all of the entries failed. Has anyone done this? Any clues? Is there somewhere I can place a 99user.ldif file *before* running setup that will cause the slapd instance to use it the first time it starts up? Thanks, brian.

[Fedora-directory-users] support for non-localy stored passwords?
by Aleksandar Milivojevic 29 Jun '05

29 Jun '05

Hi, I don't have Fedora Directory Server installed (yet). However, there's one feature from OpenLDAP that is must-have before even attempting to play with FDS. In OpenLDAP, if I use string like "{SASL}username@REALM" as a value for userPassword attribute, and have "pwcheck_method: saslauthd" in /usr/lib/sasl2/slapd.conf, then OpenLDAP will use saslauthd to authenticate the user (passing it "username@REALM" and whatever password user supplied). I've read that FDS supports SASL, but does it support this feautre too?

[Fedora-directory-users] users not showing up in directory listing
by Brian K. Jones 29 Jun '05

29 Jun '05

Hi, I wonder if anyone else has seen this who might have a clue why it happens: I have users in my directory that will show up if I do a search on the directory, either in the console or from a command line or whatever, but when I open the console, double click my directory to open it, click on the "directory" tab, and navigate to "People" on the left, there are some people who don't show up on the right. I can't figure out why that would be, because all of my entries are automatically generated from a script. They're all identical. clues? thanks, brian.
