.. _.k5login(5):
.k5login
========
DESCRIPTION
-----------
The .k5login file, which resides in a user's home directory, contains
a list of the Kerberos principals. Anyone with valid tickets for a
principal in the file is allowed host access with the UID of the user
in whose home directory the file resides. One common use is to place
a .k5login file in root's home directory, thereby granting system
administrators remote root access to the host via Kerberos.
EXAMPLES
--------
Suppose the user ``alice`` had a .k5login file in her home directory
containing the following line:
::
bob@FOOBAR.ORG
This would allow ``bob`` to use Kerberos network applications, such as
ssh(1), to access ``alice``'s account, using ``bob``'s Kerberos
tickets.
Let us further suppose that ``alice`` is a system administrator.
Alice and the other system administrators would have their principals
in root's .k5login file on each host:
::
alice@BLEEP.COM
joeadmin/root@BLEEP.COM
This would allow either system administrator to log in to these hosts
using their Kerberos tickets instead of having to type the root
password. Note that because ``bob`` retains the Kerberos tickets for
his own principal, ``bob@FOOBAR.ORG``, he would not have any of the
privileges that require ``alice``'s tickets, such as root access to
any of the site's hosts, or the ability to change ``alice``'s
password.
