Alot of our users have reported that it takes "forever" to add users to
the ldap using wlus and file import. Well, I guess there is good news
for the future.
And IMHO at least there should be a progressing feedback in/for the
browser.
But as far as I've looked into und understood the source code of WLUS
this cannot be achieved with some simple change(s) in the fileimport
function(s). :-(
Using the sarge-based debian-edu image i build at random times, I've
tested some adding:
....
- Then I tried to add 1000 users, which took about 40 minutes.
Ok this is faster, but IMHO still to slow.
I think the fileimport has to be rewritten with optimisation for speed.
but what
I forgot, was that there is a sizelimit in the response from
openldap, which by default is 500, but that we have set to 1000. i
guess raising that value to 200 would have speeded up the process.
The first 500 of the last thousand was significant faster than the
last 500.
your proposal = 200 < default = 500 < your setting = 1000
< unchanged default config of my vm-tjener = 2000
"raising" from 500 to 200 ??
So what is "higher"? And is higher=better?
Ralf: how many users did you have in advance? Have you tuned ldap to
give you more users when you query?
On behalf of Ralf...
users in advance: ~850
ldap: not tuned, just defaults from installation (sizelimit=2000)
if not, change the sizelimit, so
that it might give you all the users when you query.
we are talking about the "sizelimit" in slapd.conf, right?
Also there is some other parameters that you could tune in openldap,
e.g.?
and also, remember to edit nscd.conf on the clients.
Where is the relation between "nscd.conf on the clients" and openldap &
webmin & wlus on tjener?
Another thing that we have noticed at Ulsrud, is that the NFS mounting
some times has problems. We have hard-coded changed the use of
netgroups in /etc/exports into dns-names, and since then we have not
had any problems, I think. basically what we did was change the line
that looked like this:
/skole/tjener/home0 @ltsp-server-hosts(rw) @workstation-hosts(rw) @server-hosts(rw)
into
/skole/tjener/home0 ltspserver*(rw) @workstation-hosts(rw) @server-hosts(rw)
Do only the ltspservers have NFS-problems or why not change all to DNS?
Best wishes,
Patrick
