k5login

K5LOGIN(5)							   MIT Kerberos 							K5LOGIN(5)

NAME

       k5login - Kerberos V5 acl file for host access

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 pass-
       word.   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.
