Hi,
thanks for the file, they look ok. After looking again at what you send
I came across
Feb 23 08:14:35 idmsrvpru.idmpru.fnr.gub.uy krb5_child[4283]: KDC reply did
not match expectations
which typically indicates a canonization of the principal by the
server-side which was not expected by the client.
While version of SSSD are you using on the Ubuntu client? Recent version
of SSSD already set 'krb5_canonicalize = true' by default for
'id_provider = ipa'. Maybe your version is a bit older? Please try if it
works better if you explicitly set
krb5_canonicalize = true
in the [domain/...] section of sssd.conf and restart SSSD. At least the
'KDC reply did not match expectations' should be gone now. If the
password change still fails, please set 'debug_level = 9' in the [pam]
and [domain/...] section of sssd.conf, restart SSSD, run the test again
and send the logs from /var/log/sssd.
bye,
Sumit
