Hi,
are there any SSSD users who actively use a configuration with:
id_provider=local ?
If so, what is your use-case?
We're considering deprecating and eventually removing this provider
upstream. The replacemant for id_provider=local would be id_provider=files:
https://fedorahosted.org/sssd/wiki/DesignDocs/FilesProvider
which is already under review and later extension of the SSSD's D-Bus
interface to allow manipulating custom user attributes.
My current plan for deprecating the local provider is to only build the
provider and the tools around it if a configure-time flag is provided.
This flag would be disabled by default. Then, if noone complains,
eventually just remove the code.
1:41 p.m.
Jakub,
For my production servers I enabled local provider on the customer
facing servers. I have configured an emergency user that will not be
shown in /etc/passwd . In a hosting environment anyone can get a a
domain for a just a few $$ and this exposes passwd file. If I add the
account to /etc/passwd it could be bruteforced as most brute-forcing
scripts will reference the file. However if I add it via sss_* tools ,
the account is invisible to them.
I've read the wiki page and I understood the need for replacing it. If
id_provider=local will be removed I can live without it :)
Thanks
Mario

Interesting use-case. By the way, I've received some other feedback from
users who configure the id_provider=local, so I'm no longer sure we can
remove it. And, as Sumit noted to me off-list, the local provider is
sufficiently tested by Red Hat's QA team, so we are usually reminded
quite quickly if something goes south.
Thanks for the response.

On certain servers I want IPA authentication but the local user/group database. With sssd
1.14, I could specify pam as the only service and put files in /etc/nsswitch.conf. With
sssd 1.15, I get extra groups with that setting. I had to set id_provider=none, which is
undocumented. I'd be happy to see id_provider=files for this situation, though
id_provider=none with nsswitch seems to do what I need.
I do have a user with a static password, for cases where services are down. That can be
done in pam, by having pam_unix as well as pam_sss. It would be interesting to have sssd
handle this kind of mixed case, but it seems like this is what pam is for.

In our environment, regular users authenticate via sssd/ldap, and
emergency user(s) via PAM if/when sssd + RSA securid fails. Still
running sssd 1.14.2 on el6.
Thanks

On what distribution and with what nsswitch.conf contents do you get the
extra groups?
I would also say that id_provider=files is what you could use here..
