.Sh DESCRIPTION
|
|
These functions create a
|
|
.Dq service
|
|
principal that can, for instance, be used to lookup a key in a keytab. For both these function the
|
|
.Fa sname
|
|
parameter will be used for the first component of the created principal. If
|
|
.Fa sname
|
|
is
|
|
.Dv NULL ,
|
|
.Dq host
|
|
will be used instead.
|
|
.Fn krb5_sname_to_principal
|
|
will use the passed
|
|
.Fa hostname
|
|
for the second component. If type
|
|
.Dv KRB5_NT_SRV_HST
|
|
this name will be looked up with
|
|
.Fn gethostbyname .
|
|
If
|
|
.Fa hostname is
|
|
.Dv NULL ,
|
|
the local hostname will be used.
|
|
.Pp
|
|
.Fn krb5_sock_to_principal
|
|
will use the
|
|
.Dq sockname
|
|
of the passed
|
|
.Fa socket ,
|
|
which should be a bound
|
|
.Dv AF_INET
|
|
socket.
