Any existing tickets for \fIprincipal\fP are overwritten. \fIkinit\fP will try to acquire both Kerberos 5 and Kerberos 4 initial tickets if the appropriate configuration information is available. .SH OPTIONS .TP \fB-V\fP display verbose output. .TP \fB\-l\fP \fIlifetime\fP requests a ticket with the lifetime \fIlifetime\fP. The value for \fIlifetime\fP must be followed immediately by one of the following delimiters: .sp .nf .in +.3i \fBs\fP seconds \fBm\fP minutes \fBh\fP hours \fBd\fP days .in -.3i .fi .sp as in "kinit -l 90m". You cannot mix units; a value of '3h30m' will result in an error. .sp If the \fB-l\fP option is not specified, the default ticket lifetime (configured by each site) is used. Specifying a ticket lifetime longer than the maximum ticket lifetime (configured by each site) results in a ticket with the maximum lifetime. .TP \fB\-s\fP \fIstart_time\fP requests a postdated ticket, valid starting at \fIstart_time\fP. Postdated tickets are issued with the \fIinvalid\fP flag set, and need to be validated by the kdc before use. .TP \fB\-r\fP \fIrenewable_life\fP requests renewable tickets, with a total lifetime of \fIrenewable_life\fP. The duration is in the same format as the \fB-l\fP option, with the same delimiters. .TP \fB-f\fP request forwardable tickets. .TP \fB-F\fP request tickets which are not forwardable. .TP \fB-p\fP request proxiable tickets. .TP \fB-P\fP request tickets which are not proxiable. .TP \fB-a\fP request tickets containing the host's local address(es). .TP \fB-A\fP request address-less tickets. .TP \fB-v\fP requests that the ticket granting ticket in the cache (with the \fIinvalid\fP flag set) be passed to the kdc for validation. If the ticket is within its requested time range, the cache is replaced with the validated ticket. .TP \fB-R\fP requests renewal of the ticket-granting ticket. Note that an expired ticket cannot be renewed, even if the ticket is still within its renewable life. This option will only get Kerberos 4 tickets if the kdc must support Kerberos 5 to Kerberos 4 ticket conversion. .TP \fB\-k\fP [\fB\-t\fP \fIkeytab_file\fP] requests a host ticket, obtained from a key in the local host's \fIkeytab\fP file. The name and location of the keytab file may be specified with the \fB-t\fP \fIkeytab_file\fP option; otherwise the default name and location will be used. This option will only get Kerberos 4 tickets if the kdc must support Kerberos 5 to Kerberos 4 ticket conversion. .TP \fB\-S\fP \fIservice_name\fP specify an alternate service name to use when getting initial tickets. (Applicable to Kerberos 5 or if using both Kerberos 5 and Kerberos 4 with a kdc that supports Kerberos 5 to Kerberos 4 ticket conversion.) .SH FILES .TP /etc/krb5.keytab default location for the local host's \fBkeytab\fP file. .SH SEE ALSO klist(1), kdestroy(1), kpasswd(1), kswitch(1)
