Some compilers with -Wstring-concatenation enabled warned about a suspicious
concatenation of string literals in the initialization of the GSS-API error
message array.
At the expense of a long line, avoid this warning but explicitly concatenating
the offending string literal.
Fixes: #775
vis.h is not built on platforms (such as macOS) that already have
that header, which resulted in prototypes for Heimdal-specific
vis.h extensions being absent.
Move those prototypes to a separate header, vis-extras.h, which
must be explicitly included in order to use the Heimdal extensions.
- Don't log "Request from wrong address (ignoring)".
- Add "wrongaddr=yes" kv to final log message.
- Add request and ticket addresses (up to 3) to final log message.
If a DB does not already exist, ipropd-slave will use the compiled
default, which is not necessarily what is desired or configured in
`[kdc]`.
This change makes `hdb_default_db()` return the first dbanme in the
`[kdc]` configuration, falling back on `HDB_DEFAULT_DB`.
Also, this adds a `--database` option to `ipropd-slave`.
The codegen backend is faster than the template backend, even for
modules that don't use IOS. On x64 we see the template backend being
4% slower for TGS requests using the kdc-tester program.
So let's build both, libasn1 (codegen) and libasn1template when
configured with --disable-asn1-templating, but make sure that the
asn1_print utility is linked with libasn1template.
Eventually we'll want to either optimize the template backend better,
or add IOS and JSON printing support to the codegen backend.
While Ken Hornstein's FAQ was useful in its day, much of its content
is no longer relevant (e.g., Kerberos 4) or even actively harmful
(e.g., the latest version of MIT krb5 is not 1.2.1). It was also
somewhat MIT-krb5-focused, especially relating to configuration file
snippets, which is not necessarily a great fit for the Heimdal
documentation.
Replace it with a tutorial hosted on kerberos.org and the classic
"dialogue" from Bill Bryant.
