Description Marko Myllynen 2010-01-05 08:18:23 EST
Description of problem:
When configuring system authentication with authconfig-6.0.0-2 on Fedora 12 and using SSSD for remote authentication the "broken_shadow" parameter is missing:

account    required     pam_unix.so

This won't let any users authenticated via SSSD in, one needs to have:

account    required     pam_unix.so broken_shadow

After adding the parameter remotely authenticated users can log in.

That might actually mean that there is a bug in nss_sss module. What idendtity provider do you have configured and what 'getent passwd <username-provided-by-sssd>' prints?
Comment 2 Stephen Gallagher 2010-01-05 09:06:46 EST
I for one have an LDAP identity provider:

getent passwd sgallagh
Comment 3 Tomas Mraz 2010-01-05 09:38:40 EST
Stephen but for such passwd entry the pam_unix module should never require the broken_shadow option. Does it really not work for you without the option?
Comment 4 Marko Myllynen 2010-01-05 09:51:32 EST
I think there was a bit confusion while testing with sssd-0.7 and later versions. 

With sssd-0.7 one gets :x: but with sssd-1.0 one gets :*:. So if broken_shadow is not needed with :*: then this is should not be an issue with latest sssd versions. (Unfortunately I cannot verify this at the moment due to other issues.)
Comment 5 Tomas Mraz 2010-01-05 10:12:16 EST
OK, so please verify that it works fine as soon as you are able to do it.
I'll leave the bug open for now.
Comment 6 Marko Myllynen 2010-01-13 12:28:26 EST
I can now confirm that with 1.0 one gets :*: and also that the broken_shadow parameter is unneeded for pam_unix.so (ie, authconfig does the right thing).

Closing, not really an issue.
