## 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:

## 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:

## 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.
