[OpenAFS] Can OpenAFS be the only authenticating "entity"

[Leroy Tennison]

I know about integrated login but is it possible to create a Linux 
and/or Windows configuration where OpenAFS is the only "authenticator" 
meaning that there is no need for IDs/passwords in local files or 
another authentication service like NIS, LDAP, Samba, AD, etc?  If so, 
can you point me to information on how to do it?  Maybe I'm just not 
thinking clearly but nothing is coming to mind.  Thanks for any input.
