[Freeipa-users] SUDO does not always works on first try

[Zoske, Fabian]

Hi Jakub,

thanks for looking through the data.

I can not access the bug you mentioned. I already created an account for Bugzilla, but so far nothing.

In the second query there is a group which isn't present in the first one ((sudoUser=%ug_freeipa-administrators_int)). This is the IPA-equivalent of the AD-Group (ug_freeipa-administrators).
AD -> IPA_EXT -> IPA_INT

The second command you mentioned works and returns the correct passwd entry for my user. The first command ist not found on the client.

Best regards,
Fabian

All is OK here..

So the interesting part is that the first try doesn't match any rules
for the user:
    (Fri Oct  9 12:24:09 2015) [sssd[sudo]] [sysdb_search_group_by_gid]
    (0x0400): No such entry
    (Fri Oct  9 12:24:09 2015) [sssd[sudo]]
    [sudosrv_get_sudorules_query_cache] (0x0200): Searching sysdb with
    [(&(objectClass=sudoRule)(|(sudoUser=ALL)(sudoUser=f.zoske at de.eu.local)(sudoUser=#1948403038)(sudoUser=%ug_freeipa-administrators at de.eu.local)(sudoUser=%domänen-benutzer at de.eu.local)(sudoUser=+*)))]
    (Fri Oct  9 12:24:09 2015) [sssd[sudo]]
    [sudosrv_get_sudorules_from_cache] (0x0400): Returning 0 rules for
    [f.zoske at de.eu.local]

While the second does:
    (Fri Oct  9 12:24:14 2015) [sssd[sudo]]
    [sudosrv_get_sudorules_query_cache] (0x0200): Searching sysdb with
    [(&(objectClass=sudoRule)(|(sudoUser=ALL)(sudoUser=f.zoske at de.eu.local)(sudoUser=#1948403038)(sudoUser=%ug_freeipa-administrators at de.eu.local)(sudoUser=%domänen-benutzer at de.eu.local)(sudoUser=%admins)(sudoUser=%ug_freeipa-administrators_int)(sudoUser=+*)))]
    (Fri Oct  9 12:24:14 2015) [sssd[sudo]]
    [sudosrv_get_sudorules_from_cache] (0x0400): Returning 2 rules for
    [f.zoske at de.eu.local]

It would be interesting to see the dump of the cache from when 0 rules
are returned. I suspect the user's membership wouldn't be correct, which
might be because of the bug I linked earlier.

There are some failures here:
(Fri Oct  9 12:24:19 2015) [sssd[be[ipa-lx.com]]] [ipa_s2n_exop_send]
(0x0400): Executing extended operation

(0x0400): ldap_extended_operation result: No such object(32), (null)

But I think this is a really minor bug we fixed later where we marked
requests as failed if they simply didn't find anything. If this works
without issues:
    $ sss_cache -u f.zoske at de.eu.local
    $ getent passwd f.zoske at de.eu.local

Then you can ignore those..
