This function uses the credentials creds to set the password newpw for the principal change_password_for . It implements the set password operation of RFC 3244, for interoperability with Microsoft Windows implementations.

The error code and strings are returned in result_code , result_code_string and result_string .


If change_password_for is NULL, the change is performed on the current principal. If change_password_for is non-null, the change is performed on the principal name passed in change_password_for .
