AFS for the users of ENEAGRID/CRESCO System
The geographic distributed file system AFS, in its opensource
implementation
OpenAFS,
is one of the main component of ENEAGRID/CRESCO
infrastructure.
OpenAFS is used for the user HOMEs but also for project
related storage area.
Users can manage their projects by using
WARC utility (the
utility can be accessed only inside ENEA intranet).

OpenAFS client installation and configuration with
Kerberos 5
In AFS the authentication is based on Kerberos protocol. A
user can operate if he owns a "Kerberos Ticket" proving his
identity. The ticket is created by the Kerberos client by
contacting the Kerberos servers (Key Distribution Center -
KDC) when the user provides the proper combination of
userid/password.
ENEAGRID has several KDC distributed between its sites.
Historically AFS has used the Kerberos 4 implementation as a
native part of its software package but it has been
superseeded by the more robust Kerberos 5, in production in
ENEAGRID since 2011.
If a user wants to install OpenAFS on his workstation he must
also install Kerberos 5 and configurate properly for his
operating system. Instructions are provided for Windows, Linux
and Mac.
