package for configuration - Some suggestions

[Anthony <anthony.berger@cea.fr>]

Hello

I would like just to have some suggestions...

I have to change the authentification configuration of debian computers 
(lot of computers) at work...! In SARGE

the users will be authenticated on ldap so i need install some package : 
libpam-ldap, libnss-ldap, ldap-utils, nss-updatedb, libnss-db, 
libpam-ccreds.
Il need change configuration : /etc/nsswitch.conf, /etc/ldap.conf, 
/etc/libnss-ldap.conf and pam-ldap.conf , pam.d/common*
Create a cron task : "nss-updatedb ldap"
Add some options in resolv.conf

I have thought about create a package with dependencies and postinstall 
script to change configuration!!!
I can't create configuration file and add them in the package, can I?

Is it a good think? Have you any suggestion?

Thank you


Anthony
