[Freeipa-users] login auth fails then success

[Larry Rosen]

Thanks, that explains a lot (I didn't catch the difference in auth services).
Would this be mitigated by putting sss in front of files in nsswitch.conf)?

/etc/nsswitchconf:
passwd:     files sss
shadow:     files sss
group:      files sss

I think these are expected. Authentication using pam_unix fails because pam_unix doesn't know this particular users and then pam_sss succeeds. I wonder if the best way to deal with the log messages is just to configure logrotate a bit more aggressively?
