After 9.1 => 9.2 xauth against AD broken

Hi there,
today I updated both HA nodes from 9.1 to 9.201-25.
Of course I did not change any configuration!

Since then some users called for a non working VPN.

i figured out the following:

L2TP over IPsec is still working, authenticating against RADIUS
IPSEC is broken but ONLY when authenticating useres against AD: 
"...no connection has been authorized with policy=XAUTHPSK+XAUTHSERVER"

If i use a RADIUS-based Usergroup it works like all the other days.

Communication to the AD-Server itself is fine, I can read the entire AD from the UTM, can recreate the AD-Group-limited Usergroup and can succesfully prefetch users.

ipsec restart did not help of course and it is still strongSwan 4 and not 5.x (4.4.1git20100610)

Any Ideas?

Thanks - Chris

  • I'd never tried IPsec Remote Access with a PSK in the ASG/UTM/SG, so I didn't know it was possible to do XAUTH with a Backend Group. [:O]

    You might find a hint in your server logs, Chris, but I would have your reseller open a support case with Sophos.

    Cheers - Bob
