Issue

  • While having a username in both kerberos KDC and LDAP, how can we stack these authentication methods with SSSD the same was as in the past?
  • I have the following setup with pam_krb5 and pam_ldap, how can I use the same functionality with SSSD?
    • users exist both in a kerberos KDC and as user object in LDAP
    • In kerberos and in LDAP they are named identically
    • the LDAP user object contains a password hash
    • In the past I used to stack pam_krb5 and pam_ldap for authentication so first kerberos authentication was attempted, if not succeeding LDAP authentication was attempted
