35.Dt VERIFY_KRB5_CONF 8
36.Os HEIMDAL
37.Sh NAME
38.Nm verify_krb5_conf
39.Nd checks krb5.conf for obvious errors
40.Sh SYNOPSIS
41.Nm
42.Ar [config-file]
43.Sh DESCRIPTION
44.Nm
45reads the configuration file
46.Pa krb5.conf ,
47or the file given on the command line,
48parses it, checking verifying that the syntax is not correctly wrong.
49.Pp
50If the file is syntactically correct,
51.Nm
52tries to verify that the contents of the file is of relevant nature.
53.Sh ENVIRONMENT
54.Ev KRB5_CONFIG
55points to the configuration file to read.
56.Sh FILES
57.Bl -tag -width /etc/krb5.conf -compact
58.It Pa /etc/krb5.conf
59Kerberos 5 configuration file
60.El
61.Sh DIAGNOSTICS
62Possible output from
63.Nm
64include:
65.Bl -tag -width "FpathF"
66.It "<path>: failed to parse <something> as size/time/number/boolean"
67Usually means that <something> is misspelled, or that it contains
68weird characters. The parsing done by
69.Nm
70is more strict than the one performed by libkrb5, so strings that
71work in real life might be reported as bad.
72.It "<path>: host not found (<hostname>)"
73Means that <path> is supposed to point to a host, but it can't be
74recognised as one.
75.It <path>: unknown or wrong type
76Means that <path> is either a string when it should be a list, vice
77versa, or just that
78.Nm
79is confused.
80.It <path>: unknown entry
81Means that <string> is not known by
82.Nm .
83.El
84.Sh SEE ALSO
85.Xr krb5.conf 5
86.Sh BUGS
87Since each application can put almost anything in the config file,
88it's hard to come up with a watertight verification process. Most of
89the default settings are sanity checked, but this does not mean that
90every problem is discovered, or that everything that is reported as a
91possible problem actually is one. This tool should thus be used with
92some care.
93.Pp
94It should warn about obsolete data, or bad practice, but currently
95doesn't.
