Authentication Methods

Sun HPC Software includes two optional forms of user authentication that require the execution of user-level commands. The two methods are Kerberos Version 4 and DES. If one of these authentication methods is enforced on your Sun HPC cluster, use the commands listed in Table 3-1.

Table 3-1 User Commands Required by Authentication Methods

Authentication Method	Required Command
DES	While DES authentication is in use, you must issue the keylogin command before issuing any commands beginning with mp, such as mprun or mpps.
Kerberos 4	While Kerberos Version 4 authentication is in use, you must issue a kinit command before running any command beginning with mp, such as mprun or mpps.
