Hi again,
Last week I had to change my sssd.conf to ldap_sasl_mech=GSSAPI.
SSSD is 2.4.2 on Arch Linux.
Don't know if it is related but now I can't change password with this machine (last time it was working in February).
Anyway passwd is asking me for current password and after typing it + Enter it returning with message: Password changed.
Error which are most important (I think) is: authentication service cannot retrieve user authentication to the client (bold below in Polish).
What I see in logs:
