DESCRIPTION
The krb5_init_context() function initializes the context structure and
reads the configuration file /etc/krb5.conf.
The structure should be freed by calling krb5_free_context() when it is
no longer being used.
krb5_init_context() 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].
krb5_init_ets() adds all com_err(3) libs to context. This is done by
krb5_init_context().
krb5_add_et_list() adds a com_err(3) error-code handler func to the spec‐
ified context. The error handler must generated by the the re-rentrant
version of the compile_et(1) program. krb5_add_extra_addresses() add a
list of addresses that should be added when requesting tickets.
krb5_add_ignore_addresses() add a list of addresses that should be
ignored when requesting tickets.
krb5_get_extra_addresses() get the list of addresses that should be added
when requesting tickets.
krb5_get_ignore_addresses() get the list of addresses that should be
ignored when requesting tickets.
krb5_set_ignore_addresses() set the list of addresses that should be
ignored when requesting tickets.
krb5_set_extra_addresses() set the list of addresses that should be added
when requesting tickets.
krb5_set_fcache_version() sets the version of file credentials caches
that should be used.
krb5_get_fcache_version() gets the version of file credentials caches
that should be used.
krb5_set_dns_canonize_hostname() sets if the context is configured to
canonicalize hostnames using DNS.
krb5_get_dns_canonize_hostname() returns if the context is configured to
canonicalize hostnames using DNS.
krb5_get_kdc_sec_offset() returns the offset between the localtime and
the KDC's time. sec and usec are both optional argument and NULL can be
passed in.
krb5_set_config_files() set the list of configuration files to use and
re-initialize the configuration from the files.
krb5_prepend_config_files() parse the filelist and prepend the result to
the already existing list pq The result is returned in ret_pp and should
be freed with krb5_free_config_files().
krb5_prepend_config_files_default() parse the filelist and append that to
the default list of configuration files.
krb5_get_default_config_files() get a list of default configuration
files.
krb5_free_config_files() free a list of configuration files returned by
krb5_get_default_config_files(), krb5_prepend_config_files_default(), or
krb5_prepend_config_files().
krb5_set_use_admin_kdc() sets if all KDC requests should go admin KDC.
krb5_get_use_admin_kdc() gets if all KDC requests should go admin KDC.
krb5_get_max_time_skew() and krb5_set_max_time_skew() get and sets the
maximum allowed time skew between client and server.
