Changing Domain Password

Uh oh, Active Directory password is going to expire!

Ugh, do I need to log into a Windows workstation to change by password?

Nope, it is as easy as:

awilliam@beast01:~> smbpasswd -U DOMAIN/adam  -r example.com
Old SMB password:
New SMB password:
Retype new SMB password:
Password changed for user adam

In this case DOMAIN is the NetBIOS domain name and example.com is the domain's DNS domain. One could also specify a domain controller for -r, however in most cases the bare base domain of an Active Directory backed network will resolve to the active collection of domain controllers.
