# LX. KADM5

# 简介

These package allows you to access Kerberos V administration servers. You can create, modify, and delete Kerberos V principals and policies.

More information about Kerberos can be found at http://web.mit.edu/kerberos/www/.

Documentation for Kerberos and KADM5 can be found at http://web.mit.edu/kerberos/www/krb5-1.2/krb5-1.2.8/doc/admin_toc.html.

# 预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

## Constants for Attribute Flags

The functions kadm5_create_principal(), kadm5_modify_principal(), and kadm5_modify_principal() allow to specify special attributes using a bitfield. The symbols are defined below:

表格 1. Attributes for use by the KDC

constant
KRB5_KDB_DISALLOW_POSTDATED
KRB5_KDB_DISALLOW_FORWARDABLE
KRB5_KDB_DISALLOW_TGT_BASED
KRB5_KDB_DISALLOW_RENEWABLE
KRB5_KDB_DISALLOW_PROXIABLE
KRB5_KDB_DISALLOW_DUP_SKEY
KRB5_KDB_DISALLOW_ALL_TIX
KRB5_KDB_REQUIRES_PRE_AUTH
KRB5_KDB_REQUIRES_HW_AUTH
KRB5_KDB_REQUIRES_PWCHANGE
KRB5_KDB_DISALLOW_SVR
KRB5_KDB_PWCHANGE_SERVER
KRB5_KDB_SUPPORT_DESMD5
KRB5_KDB_NEW_PRINC

## Constants for Options

The functions kadm5_create_principal(), kadm5_modify_principal(), and kadm5_get_principal() allow to specify or return principal's options as an associative array. The keys for the associative array are defined as string constants below:

表格 2. Options for creating/modifying/retrieving principals

constant | funcdef | description
--- | --- | ---
KADM5_PRINCIPAL | long | The expire time of the princial as a Kerberos timestamp.
KADM5_PRINC_EXPIRE_TIME | long | The expire time of the princial as a Kerberos timestamp.
KADM5_LAST_PW_CHANGE | long | The time this principal's password was last changed.
KADM5_PW_EXPIRATION | long | The expire time of the principal's current password, as a Kerberos timestamp.
KADM5_MAX_LIFE | long | The maximum lifetime of any Kerberos ticket issued to this principal.
KADM5_MAX_RLIFE | long | The maximum renewable lifetime of any Kerberos ticket issued to or for this principal.
KADM5_MOD_NAME | string | The name of the Kerberos principal that most recently modified this principal.
KADM5_MOD_TIME | long | The time this principal was last modified, as a Kerberos timestamp.
KADM5_KVNO | long | The version of the principal's current key.
KADM5_POLICY | string | The name of the policy controlling this principal.
KADM5_CLEARPOLICY | long | Standard procedure is to assign the 'default' policy to new principals. KADM5_CLEARPOLICY suppresses this behaviour.
KADM5_LAST_SUCCESS | long | The KDC time of the last successfull AS_REQ.
KADM5_LAST_FAILED | long | The KDC time of the last failed AS_REQ.
KADM5_FAIL_AUTH_COUNT | long | The number of consecutive failed AS_REQs.
KADM5_RANDKEY | long | Generates a random password for the principal. The parameter password will be ignored.
KADM5_ATTRIBUTES | long | A bitfield of attributes for use by the KDC.

# 范例

This simple example shows how to connect, query, print resulting principals and disconnect from a KADM5 database.

例子 1. KADM5 extension overview example

`<?php
$handle = kadm5_init_with_password("afs-1", "GONICUS.LOCAL", "admin/admin", "password");
print "<h1>get_principals</h1>\n";
$principals = kadm5_get_principals($handle);
for( $i=0; $i<count($principals); $i++)
print "$principals[$i]<br>\n";
print "<h1>get_policies</h1>\n";
$policies = kadm5_get_policies($handle);
for( $i=0; $i<count($policies); $i++)
print "$policies[$i]<br>\n";
print "<h1>get_principal burbach@GONICUS.LOCAL</h1>\n";
$options = kadm5_get_principal($handle, "burbach@GONICUS.LOCAL" );
$keys = array_keys($options);
for( $i=0; $i<count($keys); $i++) {
$value = $options[$keys[$i]];
print "$keys[$i]: $value<br>\n";
}
$options = array(KADM5_PRINC_EXPIRE_TIME => 0);
kadm5_modify_principal($handle, "burbach@GONICUS.LOCAL", $options);
kadm5_destroy($handle);
?>`
