if i give wrong also passwd its logging in.. pl help me out how to fix
this on solaris sunfire systems.


Using Solaris with the default configuration, your password can’t be more than 8 characters. or your password ignore the characters after 8 digit.

This is due to the default crypt algorythm used to store passwords in the /etc/shadow file.

This crypt algorythm can be changed. There are a few algorythms available by default in Solaris. To know about them, have a look at /etc/security/crypt.conf

root# !% cat /etc/security/crypt.conf
# Copyright 2002 Sun Microsystems, Inc. All rights reserved.
# Use is subject to license terms.
#ident "@(#)crypt.conf 1.1 02/06/07 SMI"
# The algorithm name __unix__ is reserved.


You may want to choose md5 to enhance the security of passwords on the server.

To do so, edit the /etc/security/policy.conf file
and modify the CRYPT_DEFAULT parameter
