I guess you have an issue similar to https://bugzilla.redhat.com/show_bug.cgi?id=1297462 . The localauth plugin provided by SSSD has too stricts default settings. One is the 'enable_only = sssd' option in the config snippet. The other is that it acts authoritative for SSSD users. A fix for both was just pushed upstream today. If you currently do not need the localauth plugin you can disable it by creating an empty /var/lib/sss/pubconf/krb5.include.d/localauth_plugin file and make it unmodifiable with chattr +i /var/lib/sss/pubconf/krb5.include.d/localauth_plugin This should allow the default methods including k5login again. Please note that you might need to add the old RULE based mapping as described in https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Windows_Integration_Guide/trust-ssh.html or add .k5login files for every user to make GSSAPI authentication work smoothly. As an alternative we hope to release the next SSSD version including the patches anytime soon and later on there might be build for 7.2 available.
