The problem is on Lion this creates a *new* instance of the ccache. If you’re VPN’d and have a valid ticket, lock the screen, drop the VPN (e.g., timeout), and then unlock the screen, you will have a *second* ccache with no valid tickets in it, *plus* the ccache with your (still unexpired) tickets. If you VPN back in, some apps will see the current empty ccache and some will see the old ccache and attempt to use those tickets.

Very confusing.

http://serverfault.com/questions/55323/disable-mod-rewrite-for-subdirectory

After enabling some rewrite logging:


RewriteLog /tmp/rewrite.log
RewriteLogLevel 9


I noticed that it was immediately trying to get a 401 error document, which meant that authorization was not working and was pretty much being bypassed altogether.

The solution was to, in my httpd.conf, add:


ErrorDocument 401 "Unauthorized Access"
RewriteEngine off


Before the various Dav/Auth options. Now everything works as expected. I also got rid of the Alias directive and moved /home/user/dav to /home/user/public_html/dav; not sure if that is necessarily required, but it seems to have made a difference.

Using:

RewriteRule ^/dav – [L,PT]

doesn’t work either. /dav gets to Drupal’s page not found page. Also:

RewriteRule ^/dav/?(.*)$ /dav/$1 [L,QSA,PT]

doesn’t work. Normally I would say forget it and setup a subdomain (say dav.host.com) to get to it, but I have an SSL very host.com and want to get to the WebDAV via SSL (and since it’s on the same IP address, I’d get host-mismatch errors on the cert, which would probably break one or two of the programs I’m using).

Thank you all for trying though! The closest I got was with the RewriteBase, but that’s almost too agressive.

The URL rewrite pattern doesn’t look correct.

RewriteRule ^/dav/?(.*)$ /dav/$1 [L,QSA,PT]

The first change is just to cope with the missing slash case, that is probably just a minor issue if it is an issue at all..

But the solution is the PT option I think…

Good luck!

1) You may want to rewrite /dav to “-” which means “don’t change the URL”

2) You probably need the PT flag in the rewrite rule, because /dav is an alias.

RewriteRule ^/dav – [L]

If I remember it correctly, the rule needs to be placed before any other RewriteRule.

RewriteEngine on
RewriteBase /dav
RewriteCond %{REQUEST_URI} !=/index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*)$ /index.php?q=$1 [L,QSA]

Oh, AFAIK it doesn’t need to be in httpd.conf for it to work.

I just waited few seconds and the system has restarted anyway. But one system was different. I just couldn’t be brought down by usual tools like:
shutdown -r 0
reboot
telinit 6
init 6
Nothing worked because all is dependant on init.
I’ve found some suggestion to kill init with “kill 1″ but I was scared to do so, because the system is several hundreds of kilometers away. (that’s why reset button is not an option for me here)

So what I did?
Shut down every service running you know (except sshd of course) and do:
sync && reboot -f

I’m extremely cautios when there is a chance not to boot my system back up i know.
I hope this post helps someone. Happy upgrading!
