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 ?
, ?
, ?
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/password_change_for_SSO
If the user logs on with Single Sign-
On, checks
whether the user must change
his or her password.
Available as of
SAP Web AS 6.10, as of SAP Basis
4.6 by
Support Package
login/disable_password_logon
Controls the deactivation of password-
based logon

that systems
with

interpret.

only
generates new (backward incompatible)
password
hash values.

compatible
