freebsd-dev/crypto/heimdal/lib/krb5/verify_krb5_conf.8
Stanislav Sedov ae77177087 - Update FreeBSD Heimdal distribution to version 1.5.1. This also brings
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 VERIFY_KRB5_CONF 8
.Os HEIMDAL
.Sh NAME
.Nm verify_krb5_conf
.Nd checks krb5.conf for obvious errors
.Sh SYNOPSIS
.Nm
.Ar [config-file]
.Sh DESCRIPTION
.Nm
reads the configuration file
.Pa krb5.conf ,
or the file given on the command line,
parses it, checking verifying that the syntax is not correctly wrong.
.Pp
If the file is syntactically correct,
.Nm
tries to verify that the contents of the file is of relevant nature.
.Sh ENVIRONMENT
.Ev KRB5_CONFIG
points to the configuration file to read.
.Sh FILES
.Bl -tag -width /etc/krb5.conf -compact
.It Pa /etc/krb5.conf
Kerberos 5 configuration file
.El
.Sh DIAGNOSTICS
Possible output from
.Nm
include:
.Bl -tag -width "FpathF"
.It "<path>: failed to parse <something> as size/time/number/boolean"
Usually means that <something> is misspelled, or that it contains
weird characters. The parsing done by
.Nm
is more strict than the one performed by libkrb5, so strings that
work in real life might be reported as bad.
.It "<path>: host not found (<hostname>)"
Means that <path> is supposed to point to a host, but it can't be
recognised as one.
.It <path>: unknown or wrong type
Means that <path> is either a string when it should be a list, vice
versa, or just that
.Nm
is confused.
.It <path>: unknown entry
Means that <string> is not known by
.Nm .
.El
.Sh SEE ALSO
.Xr krb5.conf 5
.Sh BUGS
Since each application can put almost anything in the config file,
it's hard to come up with a watertight verification process. Most of
the default settings are sanity checked, but this does not mean that
every problem is discovered, or that everything that is reported as a
possible problem actually is one. This tool should thus be used with
some care.
.Pp
It should warn about obsolete data, or bad practice, but currently
doesn't.
