Not without logs: https://fedorahosted.org/sssd/wiki/Troubleshooting but my guess is that the client can't reach the server.
Also I would discourage mixing pam_ldap and pam_sss in a single PAM stack.
Same is true for pam_winbind and pam_sss if both should handled the same AD domain.
The error code '17 (Failure setting user credentials)' indicates some authentication issue. Typical examples are a wrong password or different times on the Linux client and the AD DC. The krb5_child.log might contain more details. See the link Jakub send above for details how to enable debugging.
