verify_krb5_conf: checks krb5.conf for obvious errors


verify_krb5_conf - checks krb5.conf for obvious errors




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, tries to verify that the contents of the file is of relevant nature.


KRB5_CONFIG points to the configuration file to read.


Kerberos 5 configuration file


Possible output from 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 is 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 is confused.
<path>: unknown entry
Means that <string> is not known by .


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.
