[CentOS] manage different profile with a laptop

Hi,
 
I need to use different profile with some linux CentOS  laptops.
 
- I need to connect the laptops at work  with NIS, automount, DHCP .... 
 
- The same laptops can be use at home without NIS etc..but with personal
wifi connection ....
 
- The same laptops can be use in travel without network configuration
 
Which best software to use to manage different profile ?
 
Regards.
