Set password charset


Parameter
Explanation
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 code page specified by the system language.
Caution
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 value2 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.
