verify_krb5_conf —
checks krb5.conf for obvious errors
  
    | verify_krb5_conf | [config-file] | 
verify_krb5_conf reads the configuration file
  krb5.conf, or the file given on the command line,
  parses it, checking verifying that the syntax is not correctly wrong.
If the file is syntactically correct,
    verify_krb5_conf tries to verify that the contents
    of the file is of relevant nature.
KRB5_CONFIG points to the configuration file to read.
  - /etc/krb5.conf
- Kerberos 5 configuration file
Possible output fromverify_krb5_conf include:
  - <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
      verify_krb5_confis more strict than the one
      performed by libkrb5, so strings that work in real life might be reported
      as bad.
- <path>: host not found (<hostname>)
- Means that <path> is supposed to point to a host, but it can't be
      recognised as one.
- <path>: unknown or wrong type
- Means that <path> is either a string when it should be a list, vice
      versa, or just that verify_krb5_confis
    confused.
- <path>: unknown entry
- Means that <string> is not known by
      verify_krb5_conf.
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.It should warn about obsolete data, or bad practice, but currently
    doesn't.
