several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.
We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.
- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.
- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.
- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.
- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.
- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.

.Dt LOGIN.ACCESS 5
|
|
.Os HEIMDAL
|
|
.Sh NAME
|
|
.Nm login.access
|
|
.Nd login access control table
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm login.access
|
|
file specifies on which ttys or from which hosts certain users are
|
|
allowed to login.
|
|
.Pp
|
|
At login, the
|
|
.Pa /etc/login.access
|
|
file is checked for the first entry that matches a specific user/host
|
|
or user/tty combination. That entry can either allow or deny login
|
|
access to that user.
|
|
.Pp
|
|
Each entry have three fields separated by colon:
|
|
.Bl -bullet
|
|
.It
|
|
The first field indicates the permission given if the entry matches.
|
|
It can be either
|
|
.Dq +
|
|
(allow access)
|
|
or
|
|
.Dq -
|
|
(deny access) .
|
|
.It
|
|
The second field is a comma separated list of users or groups for
|
|
which the current entry applies. NIS netgroups can used (if
|
|
configured) if preceeded by @. The magic string ALL matches all users.
|
|
A group will match if the user is a member of that group, or it is the
|
|
user's primary group.
|
|
.It
|
|
The third field is a list of ttys, or network names. A network name
|
|
can be either a hostname, a domain (indicated by a starting period),
|
|
or a netgroup. As with the user list, ALL matches anything. LOCAL
|
|
matches a string not containing a period.
|
|
.El
|
|
.Pp
|
|
If the string EXCEPT is found in either the user or from list, the
|
|
rest of the list are exceptions to the list before EXCEPT.
|
|
.Sh BUGS
|
|
If there's a user and a group with the same name, there is no way to
|
|
make the group match if the user also matches.
