[krbdev.mit.edu #8247] [Comment] KADM5_MISSING_KRB5_CONF_PARAMS should say which ones

This is a comment.  It is not sent to the Requestor(s):

This error code is worse than inspecific; it's almost always wrong.  The
required parameters are default_realm, master_key_type,
default_principal_flags, max_life, max_rlife, default_principal_expiration,
and supported_enctypes.  But all of those parameters have defaults expect for
default_realm, and a missing default_realm causes kadm5_get_config_params() to
exit early with a different error code.  The remaining parameters can only
show up as unset if they *are* set but fail to parse.  (Or in some cases, not
at all; if max_life or max_rlife don't parse, the default value is silently
used instead.)

We do yield this error code if iprop_enabled is set and iprop_logfile or
iprop_port is unset; in those cases the error code is merely inspecific.
