The MIT Kerberos Documentation lists seven different ways to store Kerberos credentials:
At the moment my Kerberos setup is storing credentials in a file in the
directory. In my
krb5.conf file the
ccache_type option is set to 4 by default:
# The following krb5.conf variables are only for MIT Kerberos. krb4_config = /etc/krb.conf krb4_realms = /etc/krb.realms kdc_timesync = 1 ccache_type = 4 forwardable = true proxiable = true
And in the MIT Kerberos Documentation about the
krb5.conf file it says about the
This parameter determines the format of credential cache types created by kinit or other programs. The default value is 4, which represents the most current format. Smaller values can be used for compatibility with very old implementations of Kerberos which interact with credential caches on the same host.
It seems that the value of the
ccache_type option does not correspond to the seven ccache types that the documentation lists. Since
4 specifies to use the "most current format" and not "KCM".
Therefore, my question is: How can I configure Kerberos to use a different ccache type, for example a keyring or memory?
