MIT Kerberos supports multiple types of credential cache to store tickets .
For example, if I want to use a persistent keyring per-user in kernel memory I can add the following to krb5.conf.
[libdefaults]
default_ccache_name = KEYRING:persistent:%{uid}
One of the options is a ccache in process memory.
How do I enable this option?
As explained in the linked document, the memory cache is using MEMORY keyword so the following should do the job:
default_ccache_name = MEMORY:
But note that this type of ccache will be destroyed once the process exits. Note that : needs to be present, otherwise it will try to store the ticket in the file called MEMORY in current working directory.
