#2964 GPO: Access denied after blocking connection to AD.
Closed: Fixed None Opened 3 years ago by lslebodn.


  • prepare user with GPO
  • authenticate in online mode
  • block connection with firewall to AD

    iptables -F

    iptables -A INPUT -s $AD_SERVER1_IP -j DROP
    iptables -A OUTPUT -d $AD_SERVER1_IP -j DROP

  • try to authenticate with the same user.

Pam system error(4) is returned for fist try:

Feb 25 04:55:17 gs-per720-01 su: pam_sss(su:auth): authentication success; logname= uid=99 euid=0 tty=pts/7 ruser=nobody rhost= user=allow_u-15330@sssdad2012.com
Feb 25 04:55:23 gs-per720-01 su: pam_sss(su:account): Access denied for user allow_u-15330@sssdad2012.com: 4 (System error)

The second attempt works as expected.

It works as expected If I force sssd_be to go into offline mode after blocking connection pkill -USR1 sssd
