3Profile Parameters for Logon and Password (Login Parameters)

To make the parameters globally effective in an SAP System (system profile parameters), set

them in the default system profile . 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

login/min_password_lng

Description

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, ß from 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.

login/min_password_diff Defines the minimum number of characters that

must be different in the new password compared to

the old password.

Default value: 1; permissible values: 1 – 40

Available as of SAP Web AS 6.10 (Until SAP

NetWeaver 6.40 (inclusive), up to 8 characters.)

login/password_expiration_time Defines the validity period of passwords in days.
