char * shishi_realm_default_guess (void);
Guesses a realm based on getdomainname() (which really is NIS/YP
domain, but if it is set it might be a good guess), or if it fails,
based on gethostname(), or if it fails, the string
"could-not-guess-default-realm". Note that the hostname is not
trimmed off of the data returned by gethostname() to get the domain
name and use that as the realm.
Returns : |
Returns guessed realm for host as a string that has
to be deallocated with free() by the caller.
|
const char * shishi_realm_default (Shishi *handle);
Get name of default realm.

char * shishi_realm_for_server_dns (Shishi *handle,char *server);
Find realm for a host using DNS lookups, according to draft-ietf-krb-wg-krb-dns-locate-03.txt. Since DNS lookups may be spoofed, relying on the realm information may result in a redirection attack. In a single-realm scenario, this only achieves a denial of service, but with cross-realm trust it may redirect you to a compromised realm. For this reason, Shishi prints a warning, suggesting that the user should add the proper 'server-realm' configuration tokens instead.
To illustrate the DNS information used, here is an extract from a zone file for the domain ASDF.COM:
_kerberos.asdf.com. IN TXT "ASDF.COM" _kerberos.mrkserver.asdf.com. IN TXT "MARKETING.ASDF.COM" _kerberos.salesserver.asdf.com. IN TXT "SALES.ASDF.COM"
Let us suppose that in this case, a client wishes to use a service on the host foo.asdf.com. It would first query:
_kerberos.foo.asdf.com. IN TXT
Finding no match, it would then query:
_kerberos.asdf.com. IN TXT

The FORWARDED flag is set by the TGS when a client presents a ticket with the FORWARDABLE flag set and requests a forwarded ticket by specifying the FORWARDED KDC option and supplying a set of addresses for the new ticket. It is also set in all tickets issued based on tickets with the FORWARDED flag set. Application servers may choose to process FORWARDED tickets differently than non-FORWARDED tickets.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff forwarded flag is set in ticket. |
int shishi_tkt_proxiable_p (Shishi_tkt *tkt);
Determine if ticket is proxiable.
The PROXIABLE flag in a ticket is normally only interpreted by the ticket-granting service. It can be ignored by application servers. When set, this flag tells the ticket-granting server that it is OK to issue a new ticket (but not a ticket-granting ticket) with a different network address based on this ticket. This flag is set if requested by the client on initial authentication. By default, the client will request that it be set when requesting a ticket-granting ticket, and reset when requesting any other ticket.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff proxiable flag is set in ticket. |
int shishi_tkt_proxy_p (Shishi_tkt *tkt);
Determine if ticket is proxy ticket.
The PROXY flag is set in a ticket by the TGS when it issues a proxy ticket. Application servers MAY check this flag and at their option they MAY require additional authentication from the agent presenting the proxy in order to provide an audit trail.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff proxy flag is set in ticket. |
int shishi_tkt_may_postdate_p (Shishi_tkt *tkt);
Determine if ticket may be used to grant postdated tickets.
The MAY-POSTDATE flag in a ticket is normally only interpreted by the ticket-granting service. It can be ignored by application servers. This flag MUST be set in a ticket-granting ticket in order to issue a postdated ticket based on the presented ticket. It is reset by default; it MAY be requested by a client by setting the ALLOW- POSTDATE option in the KRB_AS_REQ message. This flag does not allow a client to obtain a postdated ticket-granting ticket; postdated ticket-granting tickets can only by obtained by requesting the postdating in the KRB_AS_REQ message. The life (endtime-starttime) of a postdated ticket will be the remaining life of the ticket-granting ticket at the time of the request, unless the RENEWABLE option is also set, in which case it can be the full life (endtime-starttime) of the ticket-granting ticket. The KDC MAY limit how far in the future a ticket may be postdated.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff may-postdate flag is set in ticket. |
int shishi_tkt_postdated_p (Shishi_tkt *tkt);
Determine if ticket is postdated.
The POSTDATED flag indicates that a ticket has been postdated. The application server can check the authtime field in the ticket to see when the original authentication occurred. Some services MAY choose to reject postdated tickets, or they may only accept them within a certain period after the original authentication. When the KDC issues a POSTDATED ticket, it will also be marked as INVALID, so that the application client MUST present the ticket to the KDC to be validated before use.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff postdated flag is set in ticket. |
int shishi_tkt_invalid_p (Shishi_tkt *tkt);
Determine if ticket is invalid.
The INVALID flag indicates that a ticket is invalid. Application servers MUST reject tickets which have this flag set. A postdated ticket will be issued in this form. Invalid tickets MUST be validated by the KDC before use, by presenting them to the KDC in a TGS request with the VALIDATE option specified. The KDC will only validate tickets after their starttime has passed. The validation is required so that postdated tickets which have been stolen before their starttime can be rendered permanently invalid (through a hot-list mechanism).
|
input variable with ticket info. |
Returns : |
Returns non-0 iff invalid flag is set in ticket. |
int shishi_tkt_renewable_p (Shishi_tkt *tkt);
Determine if ticket is renewable.
The RENEWABLE flag in a ticket is normally only interpreted by the ticket-granting service (discussed below in section 3.3). It can usually be ignored by application servers. However, some particularly careful application servers MAY disallow renewable tickets.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff renewable flag is set in ticket. |
int shishi_tkt_initial_p (Shishi_tkt *tkt);
Determine if ticket was issued using AS exchange.
The INITIAL flag indicates that a ticket was issued using the AS protocol, rather than issued based on a ticket-granting ticket. Application servers that want to require the demonstrated knowledge of a client's secret key (e.g. a password-changing program) can insist that this flag be set in any tickets they accept, and thus be assured that the client's key was recently presented to the application client.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff initial flag is set in ticket. |
int shishi_tkt_pre_authent_p (Shishi_tkt *tkt);
Determine if ticket was pre-authenticated.
The PRE-AUTHENT and HW-AUTHENT flags provide additional information about the initial authentication, regardless of whether the current ticket was issued directly (in which case INITIAL will also be set) or issued on the basis of a ticket-granting ticket (in which case the INITIAL flag is clear, but the PRE-AUTHENT and HW-AUTHENT flags are carried forward from the ticket-granting ticket).
|
input variable with ticket info. |
Returns : |
Returns non-0 iff pre-authent flag is set in ticket. |
int shishi_tkt_hw_authent_p (Shishi_tkt *tkt);
Determine if ticket is authenticated using a hardware token.
The PRE-AUTHENT and HW-AUTHENT flags provide additional information about the initial authentication, regardless of whether the current ticket was issued directly (in which case INITIAL will also be set) or issued on the basis of a ticket-granting ticket (in which case the INITIAL flag is clear, but the PRE-AUTHENT and HW-AUTHENT flags are carried forward from the ticket-granting ticket).
|
input variable with ticket info. |
Returns : |
Returns non-0 iff hw-authent flag is set in ticket. |
int shishi_tkt_transited_policy_checked_p
(Shishi_tkt *tkt);
Determine if ticket has been policy checked for transit.
The application server is ultimately responsible for accepting or rejecting authentication and SHOULD check that only suitably trusted KDCs are relied upon to authenticate a principal. The transited field in the ticket identifies which realms (and thus which KDCs) were involved in the authentication process and an application server would normally check this field. If any of these are untrusted to authenticate the indicated client principal (probably determined by a realm-based policy), the authentication attempt MUST be rejected. The presence of trusted KDCs in this list does not provide any guarantee; an untrusted KDC may have fabricated the list.
While the end server ultimately decides whether authentication is valid, the KDC for the end server's realm MAY apply a realm specific policy for validating the transited field and accepting credentials for cross-realm authentication. When the KDC applies such checks and accepts such cross-realm authentication it will set the TRANSITED-POLICY-CHECKED flag in the service tickets it issues based on the cross-realm TGT. A client MAY request that the KDCs not check the transited field by setting the DISABLE-TRANSITED-CHECK flag. KDCs are encouraged but not required to honor this flag.
Application servers MUST either do the transited-realm checks themselves, or reject cross-realm tickets without TRANSITED-POLICY- CHECKED set.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff transited-policy-checked flag is set in ticket. |
int shishi_tkt_ok_as_delegate_p (Shishi_tkt *tkt);
Determine if ticket is ok as delegated ticket.
The copy of the ticket flags in the encrypted part of the KDC reply may have the OK-AS-DELEGATE flag set to indicates to the client that the server specified in the ticket has been determined by policy of the realm to be a suitable recipient of delegation. A client can use the presence of this flag to help it make a decision whether to delegate credentials (either grant a proxy or a forwarded ticket- granting ticket) to this server. It is acceptable to ignore the value of this flag. When setting this flag, an administrator should consider the security and placement of the server on which the service will run, as well as whether the service requires the use of delegated credentials.
|
input variable with ticket info. |
Returns : |
Returns non-0 iff ok-as-delegate flag is set in ticket. |

This means that you may have to "frame" data, so it is possible to infer the original length after decryption. Compare ASN.1 DER which contains such information.
