@Nil_kharat   To renew the Kerberos ticket, run kinit and specify both the keytab file and the principal:

# kinit -kt <keytab> <Principal>

Example:
# kinit -kt user1.keytab [email protected]

Thanks @Scharan 

How can we specify the duration for that ticket

[#5 · Accepted solution]

@Nil_kharat Ticket lifetime is set in kerberos configuration file krb5.conf in MIT kerberos,

You can check the lifetime of the ticket using # klist command after doing kinit 

You can still specify the lifetime of the ticket using -l option as shown  below

# kinit -l 30m -kt <Keytab> <principal>

Example:
kinit -l 30m -kt sai.keytab [email protected]
