The argument can either be in seconds, or a more human readable string like .Sq 1h . .It Fl p , Fl Fl proxiable Request tickets with the proxiable flag set. .It Fl R , Fl Fl renew Try to renew ticket. The ticket must have the .Sq renewable flag set, and must not be expired. .It Fl Fl renewable The same as .Fl Fl renewable-life , with an infinite time. .It Fl r Ar time , Fl Fl renewable-life= Ns Ar time The max renewable ticket life. .It Fl S Ar principal , Fl Fl server= Ns Ar principal Get a ticket for a service other than krbtgt/LOCAL.REALM. .It Fl s Ar time , Fl Fl start-time= Ns Ar time Obtain a ticket that starts to be valid .Ar time (which can really be a generic time specification, like .Sq 1h ) seconds into the future. .It Fl k , Fl Fl use-keytab The same as .Fl Fl keytab , but with the default keytab name (normally .Ar FILE:/etc/krb5.keytab ) . .It Fl v , Fl Fl validate Try to validate an invalid ticket. .It Fl e , Fl Fl enctypes= Ns Ar enctypes Request tickets with this particular enctype. .It Fl Fl password-file= Ns Ar filename read the password from the first line of .Ar filename . If the .Ar filename is .Ar STDIN , the password will be read from the standard input. .It Fl Fl fcache-version= Ns Ar version-number Create a credentials cache of version .Ar version-number . .It Fl a , Fl Fl extra-addresses= Ns Ar enctypes Adds a set of addresses that will, in addition to the systems local addresses, be put in the ticket. This can be useful if all addresses a client can use can't be automatically figured out. One such example is if the client is behind a firewall. Also settable via .Li libdefaults/extra_addresses in .Xr krb5.conf 5 . .It Fl A , Fl Fl no-addresses Request a ticket with no addresses. .It Fl n , Fl Fl anonymous Request an anonymous ticket. With the default (false) setting of the .Ar historical_anon_pkinit configuration parameter, if the principal is specified as @REALM, then anonymous PKINIT will be used to acquire an unauthenticated anonymous ticket and both the client name and (with fully RFC-comformant KDCs) realm in the returned ticket will be anonymized. Otherwise, authentication proceeds as normal and the anonymous ticket will have only the client name anonymized. With .Ar historical_anon_pkinit set to .Li true , the principal is interpreted as a realm even without an at-sign prefix, and it is not possible to obtain authenticated anonymized tickets. .It Fl Fl enterprise Parse principal as a enterprise (KRB5-NT-ENTERPRISE) name. Enterprise names are email like principals that are stored in the name part of the principal, and since there are two @ characters the parser needs to know that the first is not a realm. An example of an enterprise name is .Dq lha@e.kth.se@KTH.SE , and this option is usually used with canonicalize so that the principal returned from the KDC will typically be the real principal name. .It Fl Fl afslog Gets AFS tickets, converts them to version 4 format, and stores them in the kernel. Only useful if you have AFS. .El .Pp The .Ar forwardable , .Ar proxiable , .Ar ticket_life , and .Ar renewable_life options can be set to a default value from the .Dv appdefaults section in krb5.conf, see .Xr krb5_appdefault 3 . .Pp If a .Ar command is given, .Nm will set up new credentials caches, and AFS PAG, and then run the given command. When it finishes the credentials will be removed. .Sh ENVIRONMENT .Bl -tag -width Ds .It Ev KRB5CCNAME Specifies the default credentials cache. .It Ev KRB5_CONFIG The file name of .Pa krb5.conf , the default being .Pa /etc/krb5.conf . .El .\".Sh FILES .\".Sh EXAMPLES .\".Sh DIAGNOSTICS .Sh SEE ALSO .Xr kdestroy 1 , .Xr klist 1 , .Xr krb5_appdefault 3 , .Xr krb5.conf 5 .\".Sh STANDARDS .\".Sh HISTORY .\".Sh AUTHORS .\".Sh BUGS
