Description kod1976 2022-05-23 20:18:35 UTC 
Environment KRB5CCNAME specifies the default credentials cache according to manual page. But it is ignored if file /tmp/krb5cc_%{uid} exist and contain valid ticket (even expired one) for principal.

For example:

# printenv | grep KRB5CCNAME
# kinit some_principal
# ls -la /tmp/krb5cc_0
-rw-------   1 root  wheel    2071 May 23 16:57 krb5cc_0
# setenv KRB5CCNAME /tmp/krb5cc_test
# kinit some_principal
# ls -la /tmp/krb5cc_test
ls: /tmp/krb5cc_test: No such file or directory
# ls -la /tmp/krb5cc_0
-rw-------  1 root  wheel  2071 May 23 17:00 /tmp/krb5cc_0
# rm /tmp/krb5cc_0
# kinit some_principal
# ls -la /tmp/krb5cc_test
-rw-------  1 root  wheel  2071 May 23 17:03 /tmp/krb5cc_test
