DDEESSCCRRIIPPTTIIOONN
The kkrrbb55__iinniitt__ccoonntteexxtt() function initializes the _c_o_n_t_e_x_t structure and
reads the configuration file _/_e_t_c_/_k_r_b_5_._c_o_n_f.
The structure should be freed by calling kkrrbb55__ffrreeee__ccoonntteexxtt() when it is
no longer being used.
kkrrbb55__iinniitt__ccoonntteexxtt() returns 0 to indicate success. Otherwise an errno
code is returned. Failure means either that something bad happened dur-
ing initialization (typically [ENOMEM]) or that Kerberos should not be
used [ENXIO].
kkrrbb55__iinniitt__eettss() adds all com_err(3) libs to _c_o_n_t_e_x_t. This is done by
kkrrbb55__iinniitt__ccoonntteexxtt().
kkrrbb55__aadddd__eett__lliisstt() adds a com_err(3) error-code handler _f_u_n_c to the spec-
ified _c_o_n_t_e_x_t. The error handler must generated by the the re-rentrant
version of the compile_et(1) program. kkrrbb55__aadddd__eexxttrraa__aaddddrreesssseess() add a
list of addresses that should be added when requesting tickets.
kkrrbb55__aadddd__iiggnnoorree__aaddddrreesssseess() add a list of addresses that should be
ignored when requesting tickets.
kkrrbb55__ggeett__eexxttrraa__aaddddrreesssseess() get the list of addresses that should be added
when requesting tickets.
kkrrbb55__ggeett__iiggnnoorree__aaddddrreesssseess() get the list of addresses that should be
ignored when requesting tickets.
kkrrbb55__sseett__iiggnnoorree__aaddddrreesssseess() set the list of addresses that should be
ignored when requesting tickets.
kkrrbb55__sseett__eexxttrraa__aaddddrreesssseess() set the list of addresses that should be added
when requesting tickets.
kkrrbb55__sseett__ffccaacchhee__vveerrssiioonn() sets the version of file credentials caches
that should be used.
kkrrbb55__ggeett__ffccaacchhee__vveerrssiioonn() gets the version of file credentials caches
that should be used.
kkrrbb55__sseett__ddnnss__ccaannoonniizzee__hhoossttnnaammee() sets if the context is configured to
canonicalize hostnames using DNS.
kkrrbb55__ggeett__ddnnss__ccaannoonniizzee__hhoossttnnaammee() returns if the context is configured to
canonicalize hostnames using DNS.
kkrrbb55__ggeett__kkddcc__sseecc__ooffffsseett() returns the offset between the localtime and
the KDC's time. _s_e_c and _u_s_e_c are both optional argument and NULL can be
passed in.
kkrrbb55__sseett__ccoonnffiigg__ffiilleess() set the list of configuration files to use and
re-initialize the configuration from the files.
kkrrbb55__pprreeppeenndd__ccoonnffiigg__ffiilleess() parse the _f_i_l_e_l_i_s_t and prepend the result to
the already existing list _p_q The result is returned in _r_e_t___p_p and should
be freed with kkrrbb55__ffrreeee__ccoonnffiigg__ffiilleess().
kkrrbb55__pprreeppeenndd__ccoonnffiigg__ffiilleess__ddeeffaauulltt() parse the _f_i_l_e_l_i_s_t and append that to
the default list of configuration files.
kkrrbb55__ggeett__ddeeffaauulltt__ccoonnffiigg__ffiilleess() get a list of default configuration
files.
kkrrbb55__ffrreeee__ccoonnffiigg__ffiilleess() free a list of configuration files returned by
kkrrbb55__ggeett__ddeeffaauulltt__ccoonnffiigg__ffiilleess(), kkrrbb55__pprreeppeenndd__ccoonnffiigg__ffiilleess__ddeeffaauulltt(), or
kkrrbb55__pprreeppeenndd__ccoonnffiigg__ffiilleess().
kkrrbb55__sseett__uussee__aaddmmiinn__kkddcc() sets if all KDC requests should go admin KDC.
kkrrbb55__ggeett__uussee__aaddmmiinn__kkddcc() gets if all KDC requests should go admin KDC.
kkrrbb55__ggeett__mmaaxx__ttiimmee__sskkeeww() and kkrrbb55__sseett__mmaaxx__ttiimmee__sskkeeww() get and sets the
maximum allowed time skew between client and server.
