Hi everyone,

I'm new to this mailing list and to Kerberos.  Currently I'm working
on setting up Kerberos with PAM for system-wide authentication in a network. 
I would like to setup Kerberos principal "root/hostname@realm" for each host
in the network, and it has to correspond to the Linux userID "root" on each
host.  I can't find a way to map this so that when I log in as root, the
system knows I'm trying to authenticate as root/hostname.

Is there a way to do this on Linux?  From googling it seems like there's a
tool Ksetup that does this mapping of Windows userIDs to Kerberos principals,
and kerblink that maps RACF userIDs to Kerberos principals on IBM's z/OS, but
didn't find a tool for Linux.  

I can see doing this mapping with openLDAP but if there is a way to do this
w/o LDAP I'd like to try it first.

Thanks!
