.Sh NAME
|
|
.Nm krb5_kuserok
|
|
.Nd "verifies if a principal can log in as a user"
|
|
.Sh LIBRARY
|

Kerberos 5 Library (libkrb5, -lkrb5)
|
|
.Sh SYNOPSIS
|
|
.In krb5.h
|
|
.Ft krb5_boolean
|
|
.Fo krb5_kuserok

.Sh DESCRIPTION
|
|
This function takes a local user
|
|
.Fa name
|
|
and verifies if
|
|
.Fa principal
|
|
is allowed to log in as that user.
|
|
.Pp
|
|
First
|
|
.Nm
|
|
check if there is a local account name
|
|
.Fa username .
|
|
If there isn't,
|
|
.Nm
|
|
returns
|
|
.Dv FALSE .
|
|
.Pp
|
|
Then
|
|
.Nm
|
|
checks if principal is the same as user@realm in any of the default
|
|
realms. If that is the case,
|
|
.Nm
|
|
returns
|
|
.Dv TRUE .
|
|
.Pp
|
|
After that it reads the file
|
|
.Pa .k5login
|
|
(if it exists) in the users home directory and checks if
|
|
.Fa principal
|
|
is in the file.
|
|
If it does exists,
|
|
.Dv TRUE
|
|
is returned.
|
|
If neither of the above turns out to be true,
|
|
.DV FALSE
|
|
is returned.
|
|
.Pp
|
|
The
|
|
.Pa .k5login
|
|
should contain one principal per line.
