krb5_acl_match_file matches ACL format against each line in a file using krb5_acl_match_string(). Lines starting with # are treated like comments and ignored.
Parameters:
context Kerberos 5 context.
file file with acl listed in the file.
format format to match.
... parameter to format string.
Returns:
Return an error code or 0.
See also:
krb5_acl_match_string
krb5_acl_match_string matches ACL format against a string.
The ACL format has three format specifiers: s, f, and r. Each specifier will retrieve one argument from the variable arguments for either matching or storing data. The input string is split up using ' ' (space) and '\t' (tab) as a delimiter; multiple and '\t' in a row are considered to be the same.
List of format specifiers:
| » | s Matches a string using strcmp(3) (case sensitive). |
| » | f Matches the string with fnmatch(3). Theflags argument (the last argument) passed to the fnmatch function is 0. |
| » | r Returns a copy of the string in the char ** passed in; the copy must be freed with free(3). There is no need to free(3) the string on error: the function will clean up and set the pointer to NULL. |
Parameters:
context Kerberos 5 context
string string to match with
format format to match
... parameter to format string
Returns:
Return an error code or 0.
char *s;ret = krb5_acl_match_string(context, 'foo', 's', 'foo'); if (ret) krb5_errx(context, 1, 'acl didn't match'); ret = krb5_acl_match_string(context, 'foo foo baz/kaka', 'ss', 'foo', &s, 'foo/\*'); if (ret) { // no need to free(s) on error assert(s == NULL); krb5_errx(context, 1, 'acl didn't match'); } free(s);

Free configuration file section, the result of krb5_config_parse_file() and krb5_config_parse_file_multi().
Parameters:

s the configuration section to free
Returns:
returns 0 on successes, otherwise an error code, see krb5_get_error_message()
Free the resulting strings from krb5_config-get_strings() and krb5_config_vget_strings().

krb5_config_get_bool_default() will convert the configuration option value to a boolean value, where yes/true and any non-zero number means TRUE and other value is FALSE.
Parameters:

c a configuration section, or NULL to use the section from context
... a list of names, terminated with NULL.
Returns:
NULL if configuration string not found, a string otherwise

def_value the default value to return if no configuration found in the database.
... a list of names, terminated with NULL.
Returns:

TRUE or FALSE
Get the time from the configuration file using a relative time, for example: 1h30s
Parameters:
context A Kerberos 5 context.
c a configuration section, or NULL to use the section from context
... a list of names, terminated with NULL.
Returns:
parsed the time or -1 on error
Get the time from the configuration file using a relative time, for example: 1h30s
Parameters:
context A Kerberos 5 context.
c a configuration section, or NULL to use the section from context
def_value the default value to return if no configuration found in the database.
... a list of names, terminated with NULL.
Returns:

Parse a configuration file and add the result into res. This interface can be used to parse several configuration files into one resulting krb5_config_section by calling it repeatably.
Parameters:
context a Kerberos 5 context.
fname a file name to a Kerberos configuration file
res the returned result, must be free with krb5_free_config_files().
Returns:
Return an error code or 0, see krb5_get_error_message().
If the fname starts with '~/' parse configuration file in the current users home directory. The behavior can be disabled and enabled by calling krb5_set_home_dir_access().
krb5_config_get_bool() will convert the configuration option value to a boolean value, where yes/true and any non-zero number means TRUE and other value is FALSE.
Parameters:
context A Kerberos 5 context.
c a configuration section, or NULL to use the section from context
args a va_list of arguments
Returns:
TRUE or FALSE
Like krb5_config_get_bool_default() but with a va_list list of configuration selection.

This function takes the name of a local user and checks if principal is allowed to log in as that user.
The user may have a ~/.k5login file listing principals that are allowed to login as that user. If that file does not exist, all principals with a first component identical to the username, and a realm considered local, are allowed access.
The .k5login file must contain one principal per line, be owned by user and not be writable by group or other (but must be readable by anyone).
Note that if the file exists, no implicit access rights are given to user@LOCALREALM.
Optionally, a set of files may be put in ~/.k5login.d (a directory), in which case they will all be checked in the same manner as .k5login. The files may be called anything, but files starting with a hash (#) , or ending with a tilde (~) are ignored. Subdirectories are not traversed. Note that this directory may not be checked by other Kerberos implementations.
If no configuration file exists, match user against local domains, ie luser@LOCAL-REALMS-IN-CONFIGURATION-FILES.
Parameters:
context Kerberos 5 context.
principal principal to check if allowed to login
luser local user id
Returns:
returns TRUE if access should be granted, FALSE otherwise.
Register a plugin symbol name of specific type.
Parameters:
context a Keberos context
type type of plugin symbol
name name of plugin symbol
symbol a pointer to the named symbol
Returns:
In case of error a non zero error com_err error is returned and the Kerberos error string is set.
