.TH PWFILE 5
.CT 1 sa_nonmortals secur
.SH NAME
pwfile \- user security clearances file
.SH DESCRIPTION
The file
.F /etc/pwfile
is used by
.IR session (1)
to authorize clearances.
Each (valid) line contains the following
fields, separated by colons:
.IP
.nf
name
encrypted password
SNK key
process license (unused)
clearance (maximum ceiling)
.fi
.PP
The license and label fields are in the form
understood by
.IR labtoa (3);
thus the label field
may contain white space.
Lines with fewer than five fields
are ignored.
.PP
The name field contains a user name for option
.B -u
of
.FR /bin/session .
It is customary, but not necessary, for `users' in
.I pwfile
also to be registered in
.IR passwd (5).
.PP
The label field gives the maximum permissible label for option
.BR -l ,
and the ceiling label otherwise.
.PP
Because this file ultimately determines which users
may access which data, it is not generally writable by the public.
