|
|
.SH SYNOPSIS

|
.SH DESCRIPTION
|
|
.I kuserok
|
|
determines whether a Kerberos principal described by the structure
|
|
.I auth_data
|
|
is authorized to login as user
|
|
.I localuser
|
|
according to the authorization file
|
|
("~\fIlocaluser\fR/.klogin" by default). It returns 0 (zero) if authorized,
|
|
1 (one) if not authorized.
|
|
.PP
|
|
If there is no account for
|
|
.I localuser
|
|
on the local machine, authorization is not granted.
|
|
If there is no authorization file, and the Kerberos principal described
|
|
by
|
|
.I auth_data
|
|
translates to
|
|
.I localuser
|
|
(using
|
|
.IR krb_kntoln (3)),
|
|
authorization is granted.
|
|
If the authorization file
|
|
can't be accessed, or the file is not owned by
|
|
.IR localuser,
|
|
authorization is denied. Otherwise, the file is searched for
|
|
a matching principal name, instance, and realm. If a match is found,
|
|
authorization is granted, else authorization is denied.
|
|
.PP
|
|
The file entries are in the format:
|
|
.nf
|
|
.in +5n
|
|
name.instance@realm
|
|
.in -5n
|
|
.fi
|
|
with one entry per line.
|
|
|
|
For convenience ~localuser@LOCALREALM is
|
|
always considered to be an entry in the file even when there is no
|
|
file or the file is unreadable.
