sssd realm log

Description of problem:
Since a few days, it seems that the setting `krb5_map_user` on `/etc/sssd/sssd.conf` is not taking effect. I have this property set to `jpkroehling:jcosta`, so that my local user `jpkroehling` is translated to `jcosta` on a given Kerberos realm. It used to work, but now, I see the following on the logs:

Sep 13 13:37:56 carambola [sssd[krb5_child[15539]]][15539]: Client 'jpkroehling' not found in Kerberos database


Version-Release number of selected component (if applicable):
1.14.1 , release 2.fc24

How reproducible:
Always

Steps to Reproduce:
I basically followed the instructions on [1] to get an automatic kinit whenever I login.

[1] https://jhrozek.wordpress.com/2015/07/17/get-rid-of-calling-manually-calling-kinit-with-sssds-help/

Actual results:
There's no valid Kerberos ticket, as it tries to get one for the user `jpkroehling`.

Expected results:
A Kerberos ticket would have been obtained for `jcosta`.

Additional info:
From IRC:

<lslebodn> jpkroehling: Could you file a fedora BZ + provide log files with debug_level=9
<lslebodn> I assume that bug is caused by sysdb refactoring wich was done in 1.14

A possible workaround is to downgrade sssd:
dnf downgrade sssd-krb5 sssd sssd-krb5-common python3-sssdconfig sssd-ad sssd-krb5-common sssd-ipa sssd-ldap sssd-proxy sssd-common-pac libipa_hbac sssd-common libsss_autofs libsss_idmap libsss_sudo sssd-client
Comment 1 Juraci Paixão Kröhling 2016-09-13 12:09:44 UTC 
As a workaround, downgrading sssd seems effective:

# systemctl stop sssd
# rm -f /var/lib/sss/db/* 
# dnf downgrade sssd-krb5 sssd sssd-krb5-common python3-sssdconfig sssd-ad sssd-krb5-common sssd-ipa sssd-ldap sssd-proxy sssd-common-pac libipa_hbac sssd-common libsss_autofs libsss_idmap libsss_sudo sssd-client sssd-tools sssd-dbus python3-sss libsss_simpleifp
# systemctl start sssd
