Dmitri, in what logs should I expect to see something as a result of
setting "sudoers_debug 2"? I've searched the logs on my ipa client
that's slow, but haven't seen anything in any log file.<br>
<br>
Or did I misunderstand?<br>

When executing "sudo -i" or "sudo -iu" the first
time, we can expect a several second delay before
the command completes. If we then exit the session
and re-execute the command, it will complete almost
instantly. So whatever cache is holding this
information, if we could increase its duration, that
would certainly make our pain less. Is this a
settable value?<br>
<br>
Entering a password into a screensaver is
particularly painful. 10+ seconds before the
screensaver will exit.<br>
<br>
We are looking at environmental possibilities, like
interfaces and such. This machine is running on a
VMware VM, but we've had success deploying IPA on
VMs in the past, and our faster network is running
VMs as well (with one physical box).<br>

No. I compared the output on both networks and there's no real
difference once I accounted for HBAC on one (which produced 2
entries on the slower network that got filtered down to 1 user
match and 1 host match). But the debug output was nearly
identical.<br>

Did you see any gaps in time in the logs that are different?<br>
The flow can be the same but some operations can take longer so
there would be hint to us on what to look for.<br>

Our web UI on our slow network is exhibiting
some strange behavior as well.<br>
<br>
When selecting, for example, the "Users", it
can take up to 5 seconds to fetch 20 out of
our 56 entries.<br>
<br>
When switching to "Hosts", it took 4 seconds
for the footer to show that there would be 47
pages in total, then after 10 seconds total,
the page loaded 20 of 939 entries. When I
select a host, the previously-selected host
will actually be displayed for upwards of 8-10
seconds (while the spinning cursor spins near
the word Logout) until the host actually
loads.<br>

Is it just me, or does this, plus everything
else, start to sound like LDAP is struggling?<br>

I ran a test using ldapsearch in authenticated

nothing:<br>
