<PRE>'Twas brillig, and Guillaume Rousse at 15/05/12 15:02 did gyre and gimble:
&gt;<i> # WARNING: 'UsePAM no' is not supported in Mageia and may cause several
</I>&gt;<i> # problems.
</I>&gt;<i> I wonder about the usefulness of such comment...
</I>&gt;<i> 
</I>&gt;<i> What does means 'not supported' ? The software has been patched, and its
</I>&gt;<i> behaviour changed in such a way that it will not work as documented ? Or
</I>&gt;<i> any bug report on bugzilla will automatically result in a question 'did
</I>&gt;<i> you change UsePAM directive in sshd' before even attempting to identify
</I>&gt;<i> end user problem ?
</I>&gt;<i> 
</I>&gt;<i> And as changing ANY configuration directive in ANY software may result
</I>&gt;<i> in problems, what's the point of a specific warning here ?
</I>&gt;<i> 
</I>&gt;<i> So, what's the added value of this comment over default configuration ?
</I>
I didn't specifically think too hard about putting a comment in the
config file but I stand by it's usefulness.

Patch taken directly from Fedora | sed s/Fedora/Mageia/

The point of it is that if you turn off PAM support you may have issues
with tracking logins via SSH (i.e. pam_systemd will not be processed and
user sessions will be tracked as child processes of the ssh daemon
service itself and not as child processes of a user session. This means
that restarting SSH service will likely kill off any ssh connections,
including the current one if you set &quot;UsePAM no&quot;.

As this is an issue that has confused several people, I think extra
exposure is a good thing. If you want to deal with the bugs resulting
from incorrect settings and explain to people again and again, then
fine, we can remove it.
