The _
\bk_
\bi_
\bn_
\bi_
\bt 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
_

If you are logged in to a workstation that is running the
_
\bt_
\bo_
\be_
\bh_
\bo_
\bl_
\bd service, you do not have to use _
\bk_
\bi_
\bn_
\bi_
\bt_
\b. The _
\bt_
\bo_
\be_
\b-
_
\bh_
\bo_
\bl_
\bd login procedure will log you into Kerberos automati-
cally. You will need to use _
\bk_
\bi_
\bn_
\bi_
\bt only in those situa-
tions in which your original tickets have expired. (Tick-
ets expire in about a day.) Note as well that _
\bt_
\bo_
\be_
\bh_
\bo_
\bl_
\bd
will automatically destroy your tickets when you logout
When you use _
\bk_
\bi_
\bn_
\bi_
\bt 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, _
\bk_
\bi_
\bn_
\bi_
\bt
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 _
\b/_
\bt_
\bm_
\bp directory, in the file _
\bt_
\bk_
\bt_
\bu_
\bi_
\bd _
\b, where _
\bu_
\bi_
\bd speci-
fies your user identification number.
If you have logged in to Kerberos without the benefit of
the workstation _
\bt_
\bo_
\be_
\bh_
\bo_
\bl_
\bd system, make sure you use the _
\bk_
\bd_
\be_
\b-
_
\bs_
\bt_
\br_
\bo_
\by command to destroy any active tickets before you end
your login session. You may want to put the _
\bk_
\bd_
\be_
\bs_
\bt_
\br_
\bo_
\by com-
mand in your _
\b._
\bl_
\bo_
\bg_
\bo_
\bu_
\bt file so that your tickets will be
destroyed automatically when you logout.
The options to _
\bk_
\bi_
\bn_
\bi_
\bt are as follows:
-
\b-i
\bi _
\bk_
\bi_
\bn_
\bi_
\bt prompts you for a Kerberos instance.
-
\b-r
\br _
\bk_
\bi_
\bn_
\bi_
\bt prompts you for a Kerberos realm. This
option lets you authenticate yourself with a remote
-
\b-v
\bv Verbose mode. _
\bk_
\bi_
\bn_
\bi_
\bt prints the name of the ticket
file used, and a status message indicating the suc-
cess or failure of your login attempt.
