Subject: [PATCH 01/15] IPA: Handle empty nisDomainName
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|

Content-Transfer-Encoding: 8bit

Resolves:
|
|
https://pagure.io/SSSD/sssd/issue/3573
|
|
|
|
If nisdomain=, i.e. a blank NIS domain name, sssd was not processing the
|
|
netgroup at all. This is not in agreement with man innetgr which says "Any of
|
|
the elements in a triple can be empty, which means that anything matches. The
|
|
functions described here allow access to the netgroup databases".
|
|
|
|
This patch instead returns an empty domain as well, which eventually
|
|
produces the same output as if the netgroup was requested from the
|
|
compat tree.
|
|
|
|
To reproduce the bug:
|
|
$ ipa netgroup-add
|
|
Netgroup name: emptydom
|
|
-------------------------
|
|
Added netgroup "emptydom"
|
|
-------------------------
|
|
Netgroup name: emptydom
|
|
NIS domain name: ipa.test
|
|
IPA unique ID: 164bc15a-f4b3-11e7-acdb-525400ca6df3
|
|
$ ipa netgroup-add-member
|
|
Netgroup name: emptydom
|
|
[member user]: admin
|
|
[member group]:
|
|
[member host]:
|
|
[member host group]:
|
|
[member netgroup]:
|
|
Netgroup name: emptydom
|
|
NIS domain name: ipa.test
|
|
Member User: admin
|
|
-------------------------
|
|
Number of members added 1
|
|
-------------------------
|
|
$ ipa netgroup-mod --nisdomain="" emptydom
|
|
----------------------------
|
|
Modified netgroup "emptydom"
|
|
----------------------------
|
|
Netgroup name: emptydom
|
|
Member User: admin
|
|
|
|
Then run:
|
|
getent negroup emptydom
|
|
without the patch, the netgroup won't be resolvable. It will resolve to
|
|
a netgroup triple that looks like this after the patch:
|
|
emptydom (-,admin,)
|
|
