Kerberos kinit: Unknown credential cache type while getting default ccache

Question

I'm using Kerberos on Bash and am attempting to run the kinit command.

I keep getting this error:

kinit: Unknown credential cache type while getting default ccache

This error also appears for literally any other Kerberos command I run (klist, kdestroy, etc.).

I've set KRB5CCNAME to the following value: KEYRING:persistent:{uid}

[libdefaults]
dns_lookup_realm = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = true
rdns = false
# default_realm = EXAMPLE.COM
default_ccache_name = KEYRING:persistent:%{uid}

Could somebody suggest how to troubleshoot this further? There seems to be little documentation on this particular error.

Are you logged on as root? – Politick

No I'm not but I should have the credentials to run kinit – Archibaldo

Just comment the attribute default_ccache_name:

sudo sed -ri "s/^ default_ccache_name = (.*)/# default_ccache_name = \1/g" /etc/krb5.conf

Another common issue is kadmin.local: Invalid UID in persistent keyring name while opening default credentials cache – Seftton

Why does this fix it? OP mentioned explicitly they've set this setting to its value. Commenting it away is not a solution. – Tryptophan
