Hello, Problem description: Provide a common username/password for Linux and Windows machines. Current situation: I am using NIS and samba PDC to provide unified login access for windows and Linux machines. With this implementation, all most all our requirements are met but an important essential requirement. When users change password using passwd command, windows password 'doesn't' get updated. When users change password in Windows, Unix password 'does' get updated. How to update windows password when unix password is changed?. Creating an alias passwd for "smbpasswd -r PDC" doesnt solve all the problems. Users' account passwords are expired when they were first created. So, users are forced to change password on first login. They might log in via ssh or on console. passwd program is not used by either of them. So, creating an alias doesn't work. We need one at lower level like PAM. Any help on how this requirement can be met is appreciated. Thanks, Raj __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
