[Freeipa-users] sudo rules user and host group bugs?

Okay, I stopped sssd on the client and deleted the cache files, removed the sudo rule, started sssd and verified that the rule was gone, stopped sssd and deleted the files again, added the rule back in, restarted sssd, and still it does not work. One note, when I enter the hosts into the sudo rule in place of the host group, the effect is immediate; I do not need to restart sssd. And the opposite is true too: if I put the host group back, the rule immediately stops working. I don't think the issue is cache related; it seems to be something else. The serv_account that we are accessing with the sudo rule is external. I wouldn't expect that to matter, but perhaps it does?
I like your idea for the labels; they make sense. Right now we are just evaluating this to see if we want to go this route. So far we like it, but this could be a problem because we have a several hundred hosts that we need to manage. Having to enter each one individually will be problematic.
Thanks,
-Mark

option b) delete the rule totally and redo it from scratch.
I label rules like this,
hb-xxxx for a hbac rule
su-xxxx for a sudo rule
sc-xxxx for a sudo command group
ug-xxxx for a user group
hg-xxxx for a host groups
etc
etc
It makes the logic easier when you go into command line which I find easier to trace with than the gui at time.

That didn't work either. I set up the host group in my sudo rule, stopped sssd, renamed /var/lib/sss/db and created a new db directory, then restarted sssd. New files were created in the db directory, but it still refuses to work unless the hosts are directly specified in the sudo rule.
Thanks,

Hi,
This is a known issue Ive suffered a long time with. What would be interesting is adding another host to the host group could well work fine, that will really make you bang your head against the wall..
2 possibilities, stop the sssd daemon on the problem host, delete its cache and start it, that might fix it.
Otherwise best to,
All RH support could come up with is delete the HBAC rule, sudo rule, user group and host group and re-do it, then it will probably work fine.

I checked that and it is set correctly:
[user1 at host1 ~]$ nisdomainname
my_domain.com
If I try to run a command with the hosts specified indirectly through a host group, it fails:
[user1 at host1 ~]$ sudo -i -u serv_account
LDAP Config Summary
===================
uri ldap://ipa_server.my_domain.com
ldap_version 3
sudoers_base ou=SUDOers,dc=my_domain,dc=com
binddn uid=sudo,cn=sysaccounts,cn=etc,dc=my_domain,dc=com
bindpw **********
bind_timelimit 5000
timelimit 15
ssl start_tls
tls_checkpeer (yes)
tls_cacertfile /etc/ipa/ca.crt
===================
sudo: ldap_initialize(ld, ldap://ipa_server.my_domain.com)
sudo: ldap_set_option: debug -> 0
sudo: ldap_set_option: ldap_version -> 3
sudo: ldap_set_option: tls_checkpeer -> 1
sudo: ldap_set_option: tls_cacertfile -> /etc/ipa/ca.crt
sudo: ldap_set_option: timelimit -> 15
sudo: ldap_set_option(LDAP_OPT_NETWORK_TIMEOUT, 5)
sudo: ldap_start_tls_s() ok
sudo: ldap_sasl_bind_s() ok
sudo: no default options found!
sudo: ldap search '(|(sudoUser=user1)(sudoUser=%user1)(sudoUser=%user1s)(sudoUser=ALL))'
sudo: found:cn=my_sudo_rule,ou=sudoers,dc=my_domain,dc=com
sudo: ldap sudoHost '+hgroup1' ... not
sudo: ldap search 'sudoUser=+*'
sudo: user_matches=1
sudo: host_matches=0
sudo: sudo_ldap_lookup(0)=0x40
[sudo] password for user1:
Sorry, try again.
[sudo] password for user1:
sudo: 1 incorrect password attempt
But if I remove the host group from the sudo rule and directly add the hosts that were in the host group, it works fine:
<snip>
sudo: ldap_start_tls_s() ok
sudo: ldap_sasl_bind_s() ok
sudo: no default options found!
sudo: ldap search '(|(sudoUser=user1)(sudoUser=%user1)(sudoUser=%user1s)(sudoUser=ALL))'
sudo: found:cn=my_sudo_rule,ou=sudoers,dc=my_domain,dc=com
sudo: ldap sudoHost 'host1.my_domain.com' ... MATCH!
sudo: ldap sudoRunAsUser 'serv_account' ... MATCH!
sudo: ldap sudoCommand 'ALL' ... MATCH!
sudo: Command allowed
sudo: user_matches=1
sudo: host_matches=1
sudo: sudo_ldap_lookup(0)=0x02
[sudo] password for user1:
[serv_account at host1 ~]$
So something isn't lining up correctly with host groups in sudo rules somewhere. I just haven't been able to track it down.
Thanks,

Wow that was a mess...
To use hostgroups for sudo ensure nisdomainname is set on the hosts to the IPA domain.
