(You didn't expect me to show you that, did you?!) Using posixGroup, the attribute for adding additional members to a group is memberUid. There's a bit more to getting this all working: configuring slapd.conf with appropriate schemas, installing and configuring pam_ldap and nss_ldap, and setting up PAM correctly. I can go into excruciating detail if you like... My only irritation is that although passwd(1) in 6.3 has the code within it to allow it to be controlled by PAM, it's all currently diked out, so that you can't use passwd(1) transparently with LDAP users. (As far as I know this hasn't changed in 7.0). inetOrgPerson gives you a huge number of optional fields for other information, up to and including a JPEG photo. It inherits from organizationalPerson which inherits from person, so you need to combine all three sets of attributes to get the complete spec for inetOrgPerson (note the only MUST attributes are sn and cn from person): NAME 'inetOrgPerson' DESC 'RFC2798: Internet Organizational Person' SUP organizationalPerson STRUCTURAL MAY ( audio $ businessCategory $ carLicense $ departmentNumber $ displayName $ employeeNumber $ employeeType $ givenName $ homePhone $ homePostalAddress $ initials $ jpegPhoto $ labeledURI $ mail $ manager $ mobile $ o $ pager $ photo $ roomNumber $ secretary $ uid $ userCertificate $ x500uniqueIdentifier $ preferredLanguage $ userSMIMECertificate $ userPKCS12 ) NAME 'organizationalPerson' DESC 'RFC2256: an organizational person' SUP person STRUCTURAL MAY ( title $ x121Address $ registeredAddress $ destinationIndicator $ preferredDeliveryMethod $ telexNumber $ teletexTerminalIdentifier $ telephoneNumber $ internationaliSDNNumber $ facsimileTelephoneNumber $ street $ postOfficeBox $ postalCode $ postalAddress $ physicalDeliveryOfficeName $ ou $ st $ l ) NAME 'person' DESC 'RFC2256: a person' SUP top STRUCTURAL MUST ( sn $ cn ) MAY ( userPassword $ telephoneNumber $ seeAlso $ description ) We're hardly using any of these, but it seemed to make more sense to build it in, in case.

The install was successful, but have a question about how the root account is made. Found that the root folder was created with the user/group privileges root:wheel. Is not that a kind of security risk? I know that usually only the account used by the administrator is the one, in addition to root, that belongs to the wheel group. But also I know that sometimes admins get lazy and give for limited time extra privileges just to allow someone to do something, and that's where the danger can come. Btw, that's just my opinion. Not sure why it would be a security risk. wheel is the group for people who are allowed to su to root, so you should probably expect members of group wheel to have (or be able to get) root privs anyway. I'm not sure whether by ``root folder'' you mean / or /root , but in either case the wheel group doesn't have write access, at least on my system,and root's umask is 022, so created files aren't writable by members of wheel either. Lazy admins, of course, are a security risk. No-one should ever be given more privileges than they need, and as others have pointed out, sudo is a good answer to this problem. (In fact the first four ports that go on every box I set up, before I even think about what the box is for, are www/lynx, sysutils/screen, ports-mgmt/portupgrade and security/sudo ).

I just copied ldap.conf to nss_ldap.conf, see contents below. To try and identify the problem, can I ask - when you say slapd doesn't start, how long have you waited? There is a chicken-and-egg problem with slapd on a host which is running nss_ldap. To start a process, the system has to adopt the user and group privileges of the process owner, which means enumerating all the groups for that user from every source of group information - including LDAP on a system running nss_ldap. So, to start slapd, the system needs the group info for user ldap - from slapd. It times out and retries a few times, and eventually starts slapd using the group information from /etc/passwd and /etc/group, but the timeout and retry options by default take several minutes. The delay can be even longer depending how many other services are being started first and therefore how many nss_ldap lookup timeouts occur during boot. There are a number of possible solutions depending which version of nss_ldap you're running - searching for nss_ldap bind_policy nss_reconnect_tries will produce a number of suggestions and ``problem reports''.

I don't know if it is bad with a synrepl slave earlier version that the master, but I just didn't want to mess with the master until it proved OK and all seems perfectly great on the slave except my boot order issue It depends what else you upgraded while changing the openldap server. Earlier versions of nss_ldap had much shorter timeouts, I believe, which means the problem only manifested itself after a certain version of nss_ldap. Thanks for the response, and yes, the openldap list owner finally rejected my message and gave me the pointer to start slapd with the owner and group by id instead of name. After reading the start script to get the owner and group by id in the rc.conf file, I am now starting the process in that way. While doing that I realize that I can handle boot order by name of the file and gave it a prefix of 001. Errr, not sure what you're talking about here: man rcorder will tell you the normal way to control startup order on a recent FreeBSD. I think you'd have to be doing something rather unusual to force the old behaviour you seem to be talking about... As far as starting up with a numeric id rather than a user name, I'm not sure that will stop the lookup of group information which is actually causing the problem. Good luck.

I can do without the irritation of having to check, every time I log in to a different machine, whether the command I'm about to run or the config file I'm about to edit supports the option I'm hoping to use. I now have most of the servers running the same OS release, and running the same version of each port, all installed from a central build server with locally-built packages where possible. When something needs to be upgraded, we follow a documented procedure to make sure that there are no problems or regressions and that everything stays more or less in step. Yes, it means our ports tree is often three months or so out of date. You'd be surprised how seldom that causes a problem.

That's still a bit counter-intuitive because in normal programming languages the binding order modifies side-effects via the evaluation order. And in both cases the evaluation order would be expected to be left-to-right, with -print running last. Yes. I'm actually talking rubbish. find evaluates its argument expression left-to-right, and the ``precedence'' actually applies to term grouping rather than evaluation order. (This does affect the outcome, but not in the way I glibly said it did). What I should have said is that like a lot of programming languages, find is lazy when it comes to Boolean expressions: when it gets a TRUE in an -or or a FALSE in an -and, the value of the whole expression must be TRUE or FALSE respectively, regardless of what the remaining terms are, so why bother evaluating them? (It's usually referred to as short-circuiting). I guess what you are saying is that the side-effect of print is based-on a Boolean running-value. And without the brackets, the first test has been evaluated, but not yet ORed into that running-value, by the time that print runs. That's not quite how it works. Rewriting find /usr/src -name Makefile -or -name '*.mk' -print using extra parens to emphasise the implicit grouping, and including the implicit -and, gives: find /usr/src -name Makefile -or \( -name '*.mk' -and -print \) in other words, an -or with two terms, one of which happens to be an expression. If -name Makefile is true, the -or is satisfied, so nothing else is evaluated, and find goes on to the next filename. Otherwise, the expression in the second term has to be evaluated. If -name '*.mk' is false, the -and is satisfied (which also satisfies the -or) and find moves to the next filename. If it's true, the -and can't be satisfied without evaluating the -print. The end result is that only files matching '*.mk' are printed. Rewriting the other case, find /usr/src \( -name Makefile -or -name '*.mk' \) -and -print If the first expression is false, the -and is satisfied and the -print is not evaluated. If the first expression is true (meaning either of the -name arguments is true), then the -and can't be satisfied without evaluating the -print. The last case is find /usr/src -name Makefile -or -name '*.mk' find quickly analyses this, finds no output action, and converts it to the second form above, internally placing parens around the whole expression and an -and -print after it.

Thing is, that's a very vague thing to try to google for, and I can't seem to find it. Are there any old-timers who remember the system call in question? As I remember it, the debate revolved around the regression testing and porting effort of updating the (then very outdated) system Perl, and the large space requirements, especially as more and more CPAN modules were absorbed into the Perl core: there was some discussion about producing a lightweight version by leaving out core modules not used in the base system - at which the Perl people, not unreasonably in my view, invoked the Principle of Least Astonishment, saying that being available in every installation was rather the point of core modules. The conclusion, which made an awful lot of sense, was that the FreeBSD developers would replace the last few scripts in the base system that required Perl, so that Perl could be removed from the base system. This meant that Perl users could use the port, which tracks the current release of Perl more closely than the (properly) rather conservative update cycle Perl had had as part of the FreeBSD base. At the time, the discussion generated controversy among people not directly involved, although the discussion itself was amicable and rational, from what I remember of it. The release notes for FreeBSD 5.0 seem to be dated Jan 2003, so I would imagine digging through mailing lists for 2002 would shed more light - certainly googling for perl removed freebsd gave me a number of links to use.perl.org (for the Perl community's view), Slashdot and various other places.

Upon further inspection, it seems as though for each check, Nagios spawns a process that spawns a process that spawns a process that runs the check. I did ktrace -i -t w -p (nagiospid) on Nagios for 30 seconds and the ktrace output contained records from 2365 different processes spawned in that 30 seconds. During that time, I would expect about 800 checks to have run, so it does seem like it's right at 3 processes per check. I just don't think the system can keep up with all that fork()ing without going all out; it's just a limit of the Nagios plugin architecture. You've probably already spotted this, but this behaviour is documented in largeinstallationtweaks.html: ``Normally Nagios will fork() twice when it executes host and service checks. This is done to (1) ensure a high level of resistance against plugins that go awry and segfault and (2) make the OS deal with cleaning up the grandchild process once it exits. The extra fork() is not really necessary, so it is skipped when you enable this option. As a result, Nagios will itself clean up child processes that exit (instead of leaving that job to the OS). This feature should result in significant load savings on your Nagios installation.'' It can also be enabled separately in nagios's main config file - child_processes_fork_twice is the option to look for.

I'm just shocked that midphase care so little about their reputation or the impression this is giving, on one of the more widely-archived mailing lists, of their competence and diligence. I have employed VERP with mailing lists that I controlled. I never noticed any adverse effects. I know of several technical lists like Dovecot that employ it. Obviously, they find it useful. VERP itself is reasonably lightweight, as it modifies the envelope sender address -- something that can be applied during processing by the MTA as part of sending the message. As far as mail delivery goes, that's a very different story -- it goes from one message with tens of thousands of recipients, to tens of thousands of messages each with one recipient. Exactly - you can't batch up all the messages for users at the same domain because they now have different envelope senders. The impact of that on your mail delivery system (and the receiver's SMTP receiving system) depends on whether you have lots of individual subscribers, or several large groups. Having said that, I looked up VERP last night to check that I was right about the extra load, and came across a reference to VERP being the idea of DJB, and being acceptable to qmail users because there's no penalty load - qmail never batches up messages for the same domain, always sending each one individually. Is that true? It seems an odd design decision to me.

The failure to get the latest version(s) of Java working correctly on FreeBSD and thereby, at least in my case, make the latest version of Firefox fully usable, rests with the FreeBSD developers. I have not been able to ascertain exactly why Java cannot be made functional on a modern FreeBSD system. Other than receiving some useless suggestion about donating money to the Java foundation, or whatever it is called, nobody has responded with an answer. The bottom line is that Java appears to be functioning on other flavors of *.nix, but not FreeBSD. It would seem pretty obvious where the problem lies. Yes. It lies with Sun and Oracle, and the licensing terms that prevent the FreeBSD project from distributing modified Java packages. More generally, the problem lies with companies who won't support FreeBSD but also prevent the project from supporting their product itself. There are strong commercial interests in Linux - IBM, Red Hat, Oracle, to name three - which makes it worth spending some money supporting a product on Linux. (That goes for other products too: nvidia graphics card drivers, flash, wireless networking device drivers...) Even so there are products that have patchy support in Linux too. FreeBSD isn't as attractive a commercial target, since it has no financially powerful backers (that I'm aware of), a small market share, and not much public awareness. Some companies are prepared to sink resources into supporting it anyway, and others are prepared to release the information needed for the FreeBSD project to support their products for them. There are other companies, as I said, that won't do either. I don't think it's fair to blame the FreeBSD developers for that; nor indeed to expect the FreeBSD developers to be responsible for making Sun/Oracle's Java and the Mozilla Foundation's Firefox work.
