@RyanRies @jscott Why would dsquery * -filter (objectcategory=person) return nothing but (objectclass=user) does in an AD domain?

MikeyB

@MDMarra Weird. Works for me. Is it non-indexed?

MDMarra

me too

but not my customer

cole

@MDMarra what's the DFL

MDMarra

2000

cole

20:05

I think that's why

MDMarra

the DFL is 2003

the FFL is 2000

does person not exist in 2000 FFL?

i thought that was standard voodoo

cole

Hmm maybe it does

technet.microsoft.com/en-us/library/ee198834.aspx

Ryan Ries

Because ObjectCategory needs to be in the form of a DN

MDMarra

are you sure?

Ryan Ries

ObjectCategory : CN=Person,CN=Schema,CN=Configuration,DC=contoso,DC=corp

Nope, that was a bad guess

I take that back

Shit, I dunno :(

MDMarra

20:07

they should both return relatively similar results

Ryan Ries

PS H:\> $(get-aduser -LDAPFilter "(objectCategory=user)").Count
4185
PS H:\> $(get-aduser -LDAPFilter "(objectCategory=person)").Count
4185

MDMarra

yeah unless you're using inetOrgPerson or something weird, person and user should be nearly identical

MikeyB

@MDMarra what's the defaultObjectCategory for a Person in 2000 schema? what's the objectCategory on a random user account?

MDMarra

not sure

MikeyB

ldbsearch -H ldap://ad1 '(&(samaccountname=michael))' -k yes objectCategory
# record 1
dn: CN=Michael Brown,OU=Main,OU=Offices,DC=main,DC=adlab,DC=netdirect,DC=ca

MikeyB

but msdn.microsoft.com/en-us/library/cc221739.aspx implies it's the same all the way back to 2000 I think

voretaq7

@MichaelHampton If you make it work on any unix of my choosing, yes.

And you know I'm damn well gonna test it on AIX.

cole

Interesting: blog.backblaze.com/2013/12/04/enterprise-drive-reliability

Michael Hampton

@voretaq7 AIX runs on Intel processors now?

voretaq7

20:16

@MichaelHampton no, but AIX can damn sure be virtualized :)

@MichaelHampton Also they lose points for hardcoding /bin/bash as the interpreter

LOTS of points.

MikeyB

@voretaq7 But every linux has /bin/bash!

cole

What the shit

jscott

@MDMarra Can you see it the class, not category, Person returns the correct count? "(objectClass=Person)"

MikeyB

20:20

@Zoredache That's bloody priceless

voretaq7

@Zoredache in fairness if the clip is gone and the cable is loose you can suffer degraded performance

but still, WTF

Iain

@voretaq7 isn't he talking about the plastic cap not the clip ?

MikeyB

It's so very rare I feel the need to hand someone their ass, but this is one of those occasions where I have the butler bring it in on a tray.

@Iain I read it as talking about the retainer tail. The cap is even more useless though.

all those caps do is make it so you have to use a fucking screwdriver to release the retainer clip

Q: Guaranteed Checkmate with Rooks in High-Dimensional Chess

Given an infinite (in all directions), $n$-dimensional chess board $\mathbb{Z^n}$, and a black king. What is the minimum number of white rooks necessary that can guarantee a checkmate in a finite number of moves? To avoid trivial exceptions, assume the king starts a very large distance away from...

That kind of knowledge? That serves no real purpose?

MikeyB

@MDMarra you sends the messages, you receives them. you federate. you proliferate.

Mark Henderson

@MDMarra No, since getting married our ability to jab different things is drastically reduced

MDMarra

20:37

@MikeyB This is Cisco Jabber

all bets are off

MikeyB

@MarkHenderson ooohhhhh… good question…

Ryan Ries

@MDMarra Well let us know, because I'm stumped too

would like to know

MDMarra

I'm not crazy though, right? That query should work in a 2000 FFL 2003DFL env right?

Ryan Ries

20:40

I would think so

@MDMarra Have you tried rebooting all the DCs at the same time to rebuild the static indexes?

MDMarra

...

Mathias R. Jessen

20:42

Except for the blue in the SE logo I think it's pretty nice

MDMarra

@MathiasR.Jessen dude

voretaq7

@MathiasR.Jessen I like the blue in the SE logo actually

MDMarra

41 mins ago, by MDMarra

@RyanRies @jscott Why would dsquery * -filter (objectcategory=person) return nothing but (objectclass=user) does in an AD domain?

Iain

@voretaq7 I like the blue in the SE logo, it's a pity about the dark grey background

voretaq7

@Iain the dark background doesn't look bad on some of the sites

Mathias R. Jessen

20:44

@MDMarra Because objectCategory contains the DN of the object's class

objectClass on the other hand contains the CN of the class and all it's ancestors

MDMarra

Except, run it

In my 2012 environment, both queries return the same results

Mathias R. Jessen

@MDMarra they what? o_O

voretaq7

I really shouldn't listen to Bryan Cantrill talks at work.

I'm laughing my ass off instead of abusing Zimbra further.

MikeyB

@MDMarra dsquery * -filter (objectclass=person) -attr distinguishedname objectcategory says what?

84104

@MDMarra Likewise, but it's possible that the ldapserver portion is doing new magic.

I think I've got a 2000 domain around here somewhere...

cole

20:47

@voretaq7 I always forget what kind of work environment you work in. What industry are you in again? I feel like it's a smaller office.

MDMarra

@MikeyB CN=person, CN=schema etc etc

this is in my environment

I'm not in the customer's environment that behaves differently anymore

MikeyB

@mdmarra maybe you have another class on all the users that is overriding the objectCategory

voretaq7

@cole there's only like 10 of us on staff - healthcare

MDMarra

could be

cole

@voretaq7 ah ok.

MDMarra

20:49

I changed Jabber's default filter to (objectclass=user) but no difference

voretaq7

i'm listening to him rage about tail and trucated files and "tail DOESN'T COREDUMP!"

MikeyB

@MDMarra ldbsearch -H ldap://ad1 '(&(objectClass=person)(!(objectCategory=person)))' -k yes dn objectCategory fer instance may give you ideas

MDMarra

This isn't even my project, so our UC guy is just having them open a TAC case and letting Cisco sort it out

84104

@MDMarra What user is jabber using to search with?

MDMarra

logged in AD user

cole

20:49

@voretaq7 are these podcasts by any chance?

MDMarra

we also tried with a hardcoded user that they sync their AD to CM with

voretaq7

@cole youtube videos

84104

@MDMarra Tap all the wires, just to be sure.

cole

@voretaq7 ah I'll have to check them out later

voretaq7

(this one is the Surge 2013 lightning talks)

MDMarra

20:50

@84104 we did

wireshark on the DC shows a successful bind but then no query

84104

@MDMarra Jabber failure then?

MDMarra

Jabber logs show that no directory searcher could be contacted and is adding the DC to the LDAP blacklist

so I'm putting my money on 50% environmental 50% jabber bug

voretaq7

if you watch enough Bryan Cantrill talks you basically have a good idea what it's like to work with me when I see an OS doing stupid shit, because that's basically how I am

cole

@voretaq7 I'll have to check them out tonight.

voretaq7

"Oh OK Ubuntu Update Manager. You're going to suck because you were written in Python by someone who couldn't find their ass with both hands a flashlight and a mirror? That's fine. We're just going to tear your beating heart out and replace it with a perl script."

Mathias R. Jessen

20:52

@MDMarra I think I got it... check out the value of the defaultObjectCategory attribute on CN=User,CN=Schema,CN=Configuration,DC=contoso,DC=com if that was set to something else when the User objects were created, that would explain

MDMarra

interesting

how would that get set to something else?

Some programatic process?

voretaq7

(I don't share his dtrace fetish, but that's because thankfully nothing in this environment is complex enough for me to have to instrument a running kernel to count syscalls :-P)

cole

@voretaq7 HA

84104

@MDMarra Bind but no search makes me think the problem is jabber. Unless you mean search but not results, but even then, you should get a response.

MDMarra

no, no search

just a bind with a default objectclass=*

SpacemanSpiff

20:54

man, getting logged in sure is a pain in the ass right now

Mathias R. Jessen

@MDMarra Yes, maybe some horrible application or even maybe even - schema settings from a pre-2003 FFL

MikeyB

We just got a fax of a printout of a webpage that was printed out and a handwritten note added complaining "é is being replaced with <?> symbol"

MDMarra

but then no actual query when you search for a user in jabber

@MathiasR.Jessen Did pre-2003 actually do that?

Are are you speculating

I've been trying to find the 2000 schema docs

SpacemanSpiff

Anybody/gurus out there know about detecting problems with over-subscription on a Cisco MDS

Mathias R. Jessen

@MDMarra speculating, I'm not old enough to have cared at the time :)

MDMarra

20:54

same

84104

@MDMarra Wait, what?

MDMarra

Jabber binds and issues a query for (objectclass=*) because it's a piece of shit

84104

@MDMarra Okay, that should return... everything.

MDMarra

And then when you search for a contact, it does (&(objectcategory=person)(ANR=StringYoureSearchingFor*))

MikeyB

@MathiasR.Jessen defaultObjectCategory on CN=User is CN=Person, so it's probably massaging objectCategory=user to objectCategory=person

A: What's the silliest configuration mistake you ever made?

Worst configuration mistake that springs to mind: Renumbering a server and making sure to adjust all my server's Listen directives, my IP-Based vhosts, and the system's network configuration... ...then rebooting and realizing I didn't update the local firewall to pass traffic for the new network...

@voretaq7 sigh Now I'm thinking about that day. Where are my meds

Joel E Salas

Is CentOS just not "cool enough"

voretaq7

@Iain no we'll just write it and bug Kyle and Bart until they post it :-P

Dennis Kaarsemaker

@JoelESalas definitely not as cool as Ubuntu

it also has an utterly un-hip name

and the stink of RHEL

Q: Biggest command-line mistake?

What is the most damage (of whatever kind) that you have ever caused with a single mistaken/mistyped/misguided command line? I deleted a production system database by mistake a while back, for example, but I was lucky (i.e. backed-up) and there was no permanent data loss, lost money, property dam...

command-line

voretaq7

@MichaelHampton this is also why local firewalls SUCK.

@DennisKaarsemaker More like the dignity

Wesley

@MikeyB Dude you're so not Linux. You meant sudo yum install microsoftoffice --force --nodeps

MikeyB

@JoelESalas Because when you have a dependency or a package you want to install, you can just find the fucking thing in apt instead of going hunting around the world for an RPM.

Dennis Kaarsemaker

@Wesley dude, do you even bike :P

Joel E Salas

@MikeyB I never go hunting

Wesley

@DennisKaarsemaker So bike.

Dennis Kaarsemaker

21:49

@MikeyB that argument is largely moot these days with EPEL

Wesley

@voretaq7 Worst thing I've seen in production? Probably... me. Yeah.

MikeyB

docker run -i=true ee96b700c706 pandoc -f markdown -t odt -o /dev/stdout < Samba_4_Installation.md > Samba_4_Installation.odt

</sunglasses>

@DennisKaarsemaker EPEL has a lot, but not NEARLY as much as universe/multiverse.

voretaq7

@Wesley Cats in the datacenter are fine. It was a dog that hit the clean agent release handle.

Wesley

@voretaq7 I very nearly killed everyone with Halon.

voretaq7

@Wesley FM200 doesn't kill you.

Wesley

21:50

Sorry

Got confused.

voretaq7

(well not right away. The long term health effects may be serious)

Halon kills you pretty dead though ;-)

I told you guys about the CEO, the Computer Room, and the Cigar right?

Wesley

@voretaq7 Actually now I can't remember what that thing was. Tank was the size of a water heater... can't recall what it was.

voretaq7

@Wesley If the installation wasn't like 2 decades old probably FM200 or some other 2nd/3rd gen system

@Jacob Long story involving an old datacenter and an older CEO with a love for fine cigars and no respect for the words "Sir, you really can't smoke that in here"

?

voretaq7

INERGEN is nice. Expensive as fuck, and REALLY big tanks, but nice.

@MikeyB Yup, that'd be the one.

Joel E Salas

21:52

Whatever happened to young jacob

voretaq7

he's still around from time to time.

Iain

@JoelESalas college I think

voretaq7

@Iain oh like you can't slack off in college?!

(well...maybe not today with these 8% interest rate college loans and 30k/yr tuitions)

84104

@voretaq7 There are better way to slack off in college than hanging around here.

mossy

You can still slack off. Trust me.

Iain

21:54

@voretaq7 there should be more interesting things to do than hang out here

voretaq7

@84104 The university I went to was #1 in the country....for STD prevalence on campus.

Needless to say I did not get much action in college :-/

Scott Pack

@voretaq7 did not?

voretaq7

@ScottPack See the message above that one

Hofstra STDs? DO NOT WANT!

MikeyB

Wow. Had a customer (who in turn sells mailboxes) just ask us "I noticed that my server got really slow because all of a sudden I had 3000 mails come in over the last hour. If that's all it takes, how do Gmail and Yahoo do it?"

Dennis Kaarsemaker

besides after freshman year I stopped sleeping with straight guys (because they either turn out to be clingy and needy, or they eventually have an emotional breakdown when they realize having sex with guys means they're not straight), and most of the gay guys on campus were Rainbow Brite SuperQueers

Mark Henderson

@MikeyB Haha thats like the time someone emailed the customer a 500MB file, and both servers had maximum size limits disabled. Queue the "It took down our mail server for 3 hours. How come this doesn't happen with hotmail?"

voretaq7

@MikeyB "Fucking unicorn dust man!"

Mark Henderson

@voretaq7 Well aren't you lucky to have been so secure in your sexuality so young in your life :P

voretaq7

@MarkHenderson "Email is not a file distribution system. Maybe you should use some kind of File Transfer Protocol for that?"

@MarkHenderson I know what I like. (Attractive people! Preferably without nasty diseases or parasites!)
