The following encryption types are supported by the Directory Server:

•CLEAR means the password is stored in cleartext, with no hashing or encryption. This scheme must be used in order to use SASL DIGEST-MD5.

•SSHA (Salted Secure Hash Algorithm), the default, is the recommended method because it is the most secure. There are several bit sizes available: 140 bits (the default), 256, 384, and 512.

•SHA (Secure Hash Algorithm) is included only for backward compatibility with 4.x Directory Servers; do not use this algorithm.

•MD5 (Message Digest algorithm 5) is a commonly used standard hashing algorithm.

•CRYPT, the UNIX crypt algorithm, is provided for compatibility with UNIX passwords.

NOTE:

Passwords cannot be encrypted using the NS-MTA-MD5 password storage scheme. The storage scheme is still present but only for reasons of backward compatibility.

For more information on password policies, see the "Managing Users and Passwords" chapter in the HP-UX Directory Server administrator guide.

2.3.1.129 passwordUnlock (Unlock account)

Indicates whether users are locked out of the directory for a specified amount of time or until the administrator resets the password after an account lockout. The account lockout feature protects against hackers who try to break into the directory by repeatedly trying to guess a user's password. If this passwordUnlock attribute is set to off and the operational attribute accountUnlockTime has a value of 0, then the account is locked indefinitely.

For more information on password policies, see the "Managing Users and Passwords" chapter in the HP-UX Directory Server administrator guide.
