| 14 | The _\bk_\bi_\bn_\bi_\bt command is used to login to the Kerberos authen- |
| 15 | tication and authorization system. Note that only regis- |
| 16 | tered Kerberos users can use the Kerberos system. For |
| 17 | information about registering as a Kerberos user, see the |
| 18 | _\bk_\be_\br_\bb_\be_\br_\bo_\bs_\b(_\b1_\b) manual page. |
| 19 | |
| 20 | If you are logged in to a workstation that is running the |
| 21 | _\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- |
| 22 | _\bh_\bo_\bl_\bd login procedure will log you into Kerberos automati- |
| 23 | cally. You will need to use _\bk_\bi_\bn_\bi_\bt only in those situa- |
| 24 | tions in which your original tickets have expired. (Tick- |
| 25 | ets expire in about a day.) Note as well that _\bt_\bo_\be_\bh_\bo_\bl_\bd |
| 26 | will automatically destroy your tickets when you logout |
| 27 | from the workstation. |
| 28 | |
| 29 | When you use _\bk_\bi_\bn_\bi_\bt without options, the utility prompts |
| 30 | for your username and Kerberos password, and tries to |
| 31 | authenticate your login with the local Kerberos server. |
| 32 | |
| 33 | If Kerberos authenticates the login attempt, _\bk_\bi_\bn_\bi_\bt |
| 34 | retrieves your initial ticket and puts it in the ticket |
| 35 | file specified by your KRBTKFILE environment variable. If |
| 36 | this variable is undefined, your ticket will be stored in |
| 37 | the _\b/_\bt_\bm_\bp directory, in the file _\bt_\bk_\bt_\bu_\bi_\bd _\b, where _\bu_\bi_\bd speci- |
| 38 | fies your user identification number. |
| 39 | |
| 40 | If you have logged in to Kerberos without the benefit of |
| 41 | the workstation _\bt_\bo_\be_\bh_\bo_\bl_\bd system, make sure you use the _\bk_\bd_\be_\b- |
| 42 | _\bs_\bt_\br_\bo_\by command to destroy any active tickets before you end |
| 43 | your login session. You may want to put the _\bk_\bd_\be_\bs_\bt_\br_\bo_\by com- |
| 44 | mand in your _\b._\bl_\bo_\bg_\bo_\bu_\bt file so that your tickets will be |
| 45 | destroyed automatically when you logout. |
| 46 | |
| 47 | The options to _\bk_\bi_\bn_\bi_\bt are as follows: |
| 48 | |
| 49 | -\b-i\bi _\bk_\bi_\bn_\bi_\bt prompts you for a Kerberos instance. |
| 50 | |
| 51 | -\b-r\br _\bk_\bi_\bn_\bi_\bt prompts you for a Kerberos realm. This |
| 52 | option lets you authenticate yourself with a remote |
| 53 | Kerberos server. |
| 54 | |
| 55 | -\b-v\bv Verbose mode. _\bk_\bi_\bn_\bi_\bt prints the name of the ticket |
| 56 | file used, and a status message indicating the suc- |
| 57 | cess or failure of your login attempt. |

| 73 | -\b-l\bl _\bk_\bi_\bn_\bi_\bt prompts you for a ticket lifetime in minutes. |
| 74 | Due to protocol restrictions in Kerberos Version 4, |
| 75 | this value must be between 5 and 1275 minutes. |
