As far as I have been informed (please correct me if I'm wrong) but
there is an issue with the version of OpenLDAP that Apple ships in the
server software...They use 2.1 which is allegedly buggy compared to 2.2
which is the accepted stable series..
I had an issue with an OD master which kept crashing out, I had around
150 10.3 Macs, and somewhere in the region of 350 Red Hat clients
authenticating off it
So we moved on to plan v2.0, we created an OD replica for the RedHat
boys incase it was being caused by network issues between buildings on
campus.. The same thing happened to the OD replica, CPU use went
through the roof and the machine would hang.. The cause seemed to tie
in when users first logged in a lecture and there was a large amounts
of passwords being change.
We ended up ditching the RH boxes authenticating off the server and et
voila the CPU issues ceased..
Does anyone else have similar experiences?

Hi all,
Have a customer with around 300+ 10.3.7 clients connected to an OD. I
set it up three weeks ago and they've been slowly adding machines into
the system. The master (dual G4 Xserve, 10.3.7) has in the last week
had a series of slapd crashes (two or three a day, seemingly load
related). The log shows that the crashed thread seems to have
something to do with password server eg:
I'm hoping it's just a load issue, but the two main AFP servers (dual
G5 Xserves, 10.3.7) are both OD replicas, yet hardly any client ever
seems to use them. If i look at all three boxes' LDAP connections
right now, for example, i get this:
In the absence of any better ideas, i'm adding a StartupItem that will
randomly pick an ldap server, use ipfw to block the other two, restart
DirectoryService, and then flush ipfw again. What sort of load are
others seeing on their LDAP boxes? Is it worth adding an idle timeout
to slapd.conf?
thanks in advance
