KINIT(1)KINIT(1)NAMEkinit - Kerberos login utility
SYNOPSISkinit [ -irvl ]
DESCRIPTION
The kinit command is used to login to the Kerberos authen-
tication and authorization system. Note that only regis-
tered Kerberos users can use the Kerberos system. For
information about registering as a Kerberos user, see the
kerberos(1) manual page.
When you use kinit without options, the utility prompts
for your username and Kerberos password, and tries to
authenticate your login with the local Kerberos server.
If Kerberos authenticates the login attempt, kinit
retrieves your initial ticket and puts it in the ticket
file specified by your KRBTKFILE environment variable. If
this variable is undefined, your ticket will be stored in
the /tmp directory, in the file tktuid , where uid speci-
fies your user identification number.
Make sure you use the kdestroy command to destroy any
active tickets before you end your login session. You may
want to put the kdestroy command in your .logout file so
that your tickets will be destroyed automatically when you
logout.
The options to kinit are as follows:
-ikinit prompts you for a Kerberos instance.
-rkinit prompts you for a Kerberos realm. This
option lets you authenticate yourself with a remote
Kerberos server.
-v Verbose mode. kinit prints the name of the ticket
file used, and a status message indicating the suc-
cess or failure of your login attempt.
-lkinit prompts you for a ticket lifetime in minutes.
Due to protocol restrictions in Kerberos Version 4,
this value must be between 5 and 1275 minutes.
