Returns an the struct addrinfo in in that corresponds to the information in `host'. free:ing is handled by krb5_krbhst_free, so the returned ai must not be released.

First try this as an IP address, this allows us to add a dot at the end to stop using the search domains.

If the hostname contains a dot, assumes it's a FQDN and don't use search domains since that might be painfully slow when machine is disconnected from that network.

Set extra address to the address list that the library will add to the client's address list when communicating with the KDC.

Parameters:
contextKerberos 5 context.
addressesaddreses to set
Returns:
Returns 0 to indicate success. Otherwise an kerberos et error code is returned, see krb5_get_error_message().
KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_set_fcache_version ( krb5_context  context,
int  version 
)

Set version of fcache that the library should use.

Parameters:

KRB5_LIB_FUNCTION krb5_boolean KRB5_LIB_CALL krb5_set_home_dir_access ( krb5_context  context,
krb5_boolean  allow 
)

Enable and disable home directory access on either the global state or the krb5_context state. By calling krb5_set_home_dir_access() with context set to NULL, the global state is configured otherwise the state for the krb5_context is modified.

For home directory access to be allowed, both the global state and the krb5_context state have to be allowed.

Administrator (root user), never uses the home directory.

Parameters:
contexta Kerberos 5 context or NULL
allowallow if TRUE home directory
Returns:
the old value

const krb5_addresses *  addresses 
)

Set extra addresses to ignore when fetching addresses from the underlaying operating system.

Parameters:
contextKerberos 5 context.
addressesaddreses to ignore
Returns:
Returns 0 to indicate success. Otherwise an kerberos et error code is returned, see krb5_get_error_message().
KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_set_kdc_sec_offset ( krb5_context  context,
int32_t  sec,
int32_t  usec 
)

Set current offset in time to the KDC.

Parameters:
contextKerberos 5 context.
secseconds part of offset.
usecmicro seconds part of offset.
Returns:
returns zero
KRB5_LIB_FUNCTION void KRB5_LIB_CALL krb5_set_max_time_skew ( krb5_context  context,
time_t  t 
)

Set max time skew allowed.

Parameters:
contextKerberos 5 context.
ttimeskew in seconds.
KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_set_password ( krb5_context  context,
krb5_creds *  creds,
const char *  newpw,
krb5_principal  targprinc,
int *  result_code,
krb5_data *  result_code_string,
krb5_data *  result_string 
)

Change password using creds.

Parameters:
contexta Keberos context
credsThe initial kadmin/passwd for the principal or an admin principal
newpwThe new password to set
targprincif unset, the default principal is used.
result_codeResult code, KRB5_KPASSWD_SUCCESS is when password is changed.
result_code_stringbinary message from the server, contains at least the result_code.
result_stringA message from the kpasswd service or the library in human printable form. The string is NUL terminated.
Returns:
On sucess and *result_code is KRB5_KPASSWD_SUCCESS, the password is changed.

KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_set_real_time ( krb5_context  context,
krb5_timestamp  sec,
int32_t  usec 
)

Parameters:
contextKeberos 5 context.
secThe applications new of "now" in seconds
usecThe applications new of "now" in micro seconds
Returns:
Kerberos 5 error code, see krb5_get_error_message().

If the caller passes in a negative usec, its assumed to be unknown and the function will use the current time usec.
