sap系统关于系统登录和密码的主要参数设置

To make the parameters globally effective in an SAP System (system
profile parameters), set them in the default system profile DEFAULT.PFL.
However, to make them instance-specific, you must set them in the profiles
of each application server in your SAP System.
To display the documentation for one of the parameters, choose Tools CCMS
Configuration Profile Maintenance (transaction RZ10), specify the parameter name and
choose Display. On the following screen, choose the Documentation pushbutton.
Password Checks
Parameter Description
login/min_password_lng Defines the minimum length of the password.
Default value: 3; permissible values: 3 – 40
Until SAP NetWeaver 6.40 (inclusive), up to 8
characters.
login/min_password_digits Defines the minimum number of digits (0-9) in
passwords.
Default value: 0; permissible values: 0 – 40
Available as of SAP Web AS 6.10 (Until SAP
NetWeaver 6.40 (inclusive), up to 8 characters.)
login/min_password_letters Defines the minimum number of letters (A-Z) in
passwords.
Default value: 0; permissible values: 0 – 40
Available as of SAP Web AS 6.10 (Until SAP
NetWeaver 6.40 (inclusive), up to 8 characters.)
login/min_password_specials Defines the minimum number of special characters
in the password Permissible special characters
are, in particular, !"
$%&/()=?'`*+~#-_.,;:{[]}\<>| and space
After SAP NetWeaver 6.40, all characters that are
not letters or digits are regarded as special
characters.
Default value: 0; permissible values: 0 – 40
Available as of SAP Web AS 6.10 (Until SAP
NetWeaver 6.40 (inclusive), up to 8 characters.)
login/password_charset This parameter defines the characters of which
a password can consist.
Permissible values:
▪0 (restrictive): The
password can only consist of digits,
letters, and the following (ASCII) special
characters :!"
$%&/()=?'`*+~#-_.,;:{[]}\<>| and space ▪ 1 (backward compatible, default value): The password can consist
of any characters including national
special characters (such as ä, ç, ßfrom
ISO Latin-1, 8859-1). However, all
characters that are not contained in the
set above (for value = 0) are mapped to the
same special character, and the system
therefore does not differentiate between
them.
▪ 2 (not backward compatible): The password can consist of any
characters. It is converted internally
into the Unicode format UTF-8. If your
system does not support Unicode, you may
not be able to enter all characters on the
logon screen. This restriction is limited
by the codepage specified by the system
language.
With login/password_charset = 2, passwords are stored in a format that systems with older kernels cannot interpret. You must therefore only set the profile parameter to the value 2 after you have ensured that all systems involved support the new password coding.
Available in the standard system as of SAP Web AS 6.40.
