Hi,
We're being hit by occasional very high load (up to 23 on a SUN Fire
v440) on our LDAP server
coming from a query of (objectClass=posixAccount). This currently
returns over 54,000 entries ...
This is coming from the getpwent() call in util_getent.c:getpwent_list()
This is coming from srv_samr_nt.c:get_memberuids()
But we're having trouble working out what triggers this call: it
happens mostly during the morning startup period, but happens
occasionally thoughout the day. It is not triggered by anything we
can think of with our clients MS/Win/XP, smbclient, Mac OS/X. But
might be coming from clients we can't replicate: NT4, W2K, ???
Is there any alternative to getting the list of all users in
get_memberuids() ?
This causes a 2 hr slot in the morning when users have trouble loggin
in, which is effecting about 6000 users!
