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.

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,
!
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
?
,
?
, ?
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.
Default
value: 0; permissible values: 0 -1000

login/disable_password_logon

, passwords are stored in a
format that systems
with older kernels
cannot interpret. The system only
generates new (backward incompatible)
password
hash values.

The system also
generates backward compatible
password
hash values internally, but does not
evaluate these for password-based
