Yeah, I want to be able to select whether my computer runs at 3.6 GHz or 4 MHz.

Outperforming the CPU's own fsqrt instruction is quite a righteous hack.

This is really wild. Qt now supports the rendering of content and widgets into a 3D scene. As a demo of this technology, they stuck a bunch of live widgets (including video) into the Castle Wolfenstein code.

It's really wild ... especially when they get to the point where it recurses into itself.

I wonder what the longest word using only the letters a-f might be.

(Longest word in English, I suppose I should say).

The traditional challenge is to find words with eight letters or less, so they can fit in places designed to accept 32-bit hexadecimal values. 0xDEADBEEF is the most commonly found one, although my favorite is 0xDECAFBAD.

Well, with the 64 bit systems, we could easily double the space now.

Are there any LDAP super-experts out there? I'm writing an LDAP authentication module and I'm interested in knowing which attributes I can count on being present in which servers (OpenLDAP, M$ Active Directory, Novell eDirectory).

On my test server (running OpenLDAP) I'm searching for the username in the "uid" attribute, then fetching the user's display name from the "cn" attribute, and obtaining a unique user number from the "uidNumber" attribute.

I suppose that would fail miserably on servers that don't have the RFC2307 POSIX/NIS schema installed, right? Definitely the uidNumber attribute is part of that schema, but what about uid and cn? Can I count on those always being available?

I'm not an expert, so I can't really answer your question.. except to say that cn should always be there. But I was wondering.. you said a while back that you would have to remove the existing LDAP module to add this one. Why?
It seems to me that they perform independent functions.

It's not strictly necessary, but I'd like to remove it because it's always been a kludgy hack that I'm not very proud of, it's not very flexible, doesn't cover enough functionality to be useful, and as far as I can tell, nobody is using it.

The next couple of versions are going to issue warnings about the module's deprecation. If there's an outcry and it turns out that this module was actually being used out there, then we will of course reverse the decision to remove it.

At one point I was attempting to make Thunderbird + Lightning talk to citadel in a way that would be an acceptable substitute for Outlook/Exchange. And IIRC I used the Citadel LDAP. I can't remember if I didn't end up having to use a plugin to synchronize my contacts using some other protocol anyway...
But I eventually gave up because I could not get the calendar sync working.

[#] Thu Feb 19 2009 14:22:26 EST from IGnatius T Foobar @ Uncensored

And that's part of the problem; the LDAP connector only pushes the Global Address Book, not each user's personal address book or any other address book.
There are better ways of getting Thunderbird+Lightning to talk to Citadel now, which use DAV and/or IMAP and get the job done much better.

Last I tried, Lighting did only caldav and ical, citadel only did groupdav.
So it was a no go on the calendar. I could not find a functional groupdav plugin nor did the syncml plugin work for me (obviously I would have used funambol for that, not citadel). That's why I gave up on the project.

every ldap object has a scheme which defines what attributes are present. I think it's OO-polymorphic, schemas can extend other schemas. anyway, you just need to figure out where's the schema library for your particular server

speaking of which, does citadel implement Exchange's "shared task lists" feature?

[#] Thu Feb 19 2009 16:44:56 EST from IGnatius T Foobar @ Uncensored

[Reply] [ReplyQuoted] [Headers] [Print]

Citadel does ical. There are a couple of connectors available other than the ones you mentioned ... there's the SyncKolab plugin which uses IMAP, and there's the Inverse.CA GroupDAV connector, which uses GroupDAV. CalDAV is planned but not quite here yet.

LS: I don't know how Exchange's shared task lists work, but if it shows up as an ordinary tasks folder that happens to be a shared folder, then I don't see any reason why our Outlook connector wouldn't handle it as such.

What I was thinking of doing is just querying for the attribute names I'd like to use, in order of preference. uidNumber would make life really easy, but I can't count on it being present outside of the unix world. I really don't want to store the entire DN in the user record. I could store a 32-bit hash of the DN in the space where I would otherwise store a uidNumber. That would work except in places where it needs to be looked up in the other direction (there's only one place we do that, which is in the auto-purger, when we want to determine whether the host account has been deleted so we can decide whether to delete the Citadel account as well).

My experience so far with connecting things to LDAP authentication has been at the network edge -- authenticating access to VPN concentrators via directory services, that sort of thing. They usually offer a couple of different modes, such as "POSIX/NIS [RFC2307] mode," "Active Directory mode," and "program the attributes manually mode." That's fine if everyone is smart, but I like to write software that is capable of being installed by people that aren't smart without them having to pester the support resources.
