Description Gowrishankar Rajaiyan 2011-09-07 11:28:00 UTC 
Description of problem:


Version-Release number of selected component (if applicable):
sssd-1.5.1-49.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Configure a hbacrule on the server as (make sure to have multiple external hosts and one managed host)
[root@bumblebee ~]# ipa hbacrule-show  rule2 --all --raw
  dn: ipauniqueid=bcc94bbe-d91d-11e0-aafb-525400deab7b,cn=hbac,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  cn: rule2
  ipaenabledflag: TRUE
  externalhost: external.lab.eng.pnq.redhat.com
  externalhost: ironhide.lab.eng.pnq.redhat.com
  sourcehost: fqdn=mudflap.lab.eng.pnq.redhat.com,cn=computers,cn=accounts,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  memberhost: fqdn=bumblebee.lab.eng.pnq.redhat.com,cn=computers,cn=accounts,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  memberuser: uid=shanks,cn=users,cn=accounts,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  accessruletype: allow
  ipauniqueid: bcc94bbe-d91d-11e0-aafb-525400deab7b
  memberservice: cn=vsftpd,cn=hbacservices,cn=hbac,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  memberservice: cn=sshd,cn=hbacservices,cn=hbac,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  objectclass: ipaassociation
  objectclass: ipahbacrule

2. Try ssh from the external host ironhide.lab.eng.pnq.redhat.com to the target host bumblebee.lab.eng.pnq.redhat.com

  
Actual results:
ssh auth session hangs and sssd crashes.

Expected results:
Auth should be successful without any crash.

At times I also see the following message in the sssd domain logs:

This is reproduced more often if you have the following rule on your server:

# ipa hbacrule-show  rule2 --all --raw
  dn: ipauniqueid=bcc94bbe-d91d-11e0-aafb-525400deab7b,cn=hbac,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  cn: rule2
  ipaenabledflag: TRUE

  memberhost: fqdn=bumblebee.lab.eng.pnq.redhat.com,cn=computers,cn=accounts,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
  memberuser: uid=shanks,cn=users,cn=accounts,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=com
