Both LDAP and NIS authentication optionally support Kerberos authentication. In the case of IPA, Kerberos is fully integrated. Kerberos provides a secure connection over standard ports, and it also allows offline logins if you enable credential caching in SSSD.

Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory,. After calling ipa-cacert-manage install (that puts the new CA in LDAP store), you need to call ipa-certupdate on all FreeIPA machines (to get the CA from the LDAP store and put it in the local NSS databases). Ipa cert-request is used to request new certificates for users, hosts or services. The certificate is signed by FreeIPA embedded CA.

  • No one can just come to the UN without a network. IPA was a great provider and gave us the ‘once in a lifetime experience and opportunity to shout out the tiny voices’. IPA made a difference in our experience here at the UN. My various experiences here in New York are like different kinds of food we have tasted here.
  • A 4-digit pin can't be 'stretched' enough to make brute-forcing it unfeasible in this way, because the desired time required for an attacker to try them all (say 3 years, the life of the average ATM/debit card, assuming you changed your PIN with every new card) would make the time required to generate one PIN-based key unfeasible (2 minutes, 37.
  • The TGT is encrypted with a session key known only between the KDC and user (also known as a principal) - this key is most often generated with the users password. IPA/IDM uses symmetric key cryptography when generating TGT's.

Session Ipa Definition

Figure 23.5 illustrates how a Kerberos Key Distribution Center (KDC) authenticates a principal, which can be a user or a host, and grants a Ticket Granting Ticket (TGT) that the principal can use to gain access to a service.

Figure 23.5 Kerberos Authentication


The steps in the process are:

  1. A principal name and key are specified to the client.

  2. The client sends the principal name and a request for a TGT to the KDC.

    The KDC generates a session key and a TGT that contains a copy of the session key, and uses the Ticket Granting Service (TGS) key to encrypt the TGT. It then uses the principal's key to encrypt both the already encrypted TGT and another copy of the session key.

  3. The KDC sends the encrypted combination of the session key and the encrypted TGT to the client.

    The client uses the principal's key to extract the session key and the encrypted TGT.

  4. When the client want to use a service, usually to obtain access to a local or remote host system, it uses the session key to encrypt a copy of the encrypted TGT, the client’s IP address, a time stamp, and a service ticket request, and it sends this item to the KDC.

    The KDC uses its copies of the session key and the TGS key to extract the TGT, IP address, and time stamp, which allow it to validate the client. Provided that both the client and its service request are valid, the KDC generates a service session key and a service ticket that contains the client’s IP address, a time stamp, and a copy of the service session key, and it uses the service key to encrypt the service ticket. It then uses the session key to encrypt both the service ticket and another copy of the service session key.

    The service key is usually the host principal's key for the system on which the service provider runs.

  5. The KDC sends the encrypted combination of the service session key and the encrypted service ticket to the client.

    The client uses its copy of the session key to extract the encrypted service ticket and the service session key.

  6. The client sends the encrypted service ticket to the service provider together with the principal name and a time stamp encrypted with the service session key.

    The service provider uses the service key to extract the data in the service session ticket, including the service session key.

  7. The service provider enables the service for the client, which is usually to grant access to its host system.

    If the client and service provider are hosted on different systems, they can each use their own copy of the service session key to secure network communication for the service session.

Note the following points about the authentication handshake:

  • Steps 1 through 3 correspond to using the kinit command to obtain and cache a TGT.

  • Steps 4 through 7 correspond to using a TGT to gain access to a Kerberos-aware service.

  • Authentication relies on pre-shared keys.

  • Keys are never sent in the clear over any communications channel between the client, the KDC, and the service provider.

  • At the start of the authentication process, the client and the KDC share the principal's key, and the KDC and the service provider share the service key. Neither the principal nor the service provider know the TGS key.

  • At the end of the process, both the client and the service provider share a service session key that they can use to secure the service session. The client does not know the service key and the service provider does not know the principal's key.

  • The client can use the TGT to request access to other service providers for the lifetime of the ticket, which is usually one day. The session manager renews the TGT if it expires while the session is active.
