Description of problem: Failover to krb5_backup_kpasswd doesn't work Version-Release number of selected component (if applicable): sssd-1.9.2-59.el6 How reproducible: Always Steps to Reproduce: 1. [domain/LDAP-KRB5] debug_level = 0xFFF0 id_provider = ldap ldap_uri = ldap://ldapserver.example.com ldap_search_base = dc=example,dc=com auth_provider = krb5 krb5_realm = EXAMPLE.COM krb5_server = kdc.example.com krb5_kpasswd = kdc1.example.com <== KDC doesn't exist on this machine krb5_backup_kpasswd = kdc.example.com 2. Try to change password: # ssh -l puser1 localhost puser1@localhost's password: Last login: Thu Dec 27 18:23:42 2012 from localhost -sh-4.1$ passwd Changing password for user puser1. Current Password: New password: Retype new password: passwd: Authentication token manipulation error -sh-4.1$ Actual results: Password change fails. It seems sssd doesn't failover to the kpasswd server specified under krb5_backup_kpasswd /var/log/secure shows: Dec 27 18:25:49 dhcp201-200 passwd: pam_sss(passwd:chauthtok): system info: [Ticket expired] Dec 27 18:25:49 dhcp201-200 passwd: pam_sss(passwd:chauthtok): Password change failed for user puser1: 20 (Authentication token manipulation error) Expected results: Failover should work.
