Trying to set up kerberos on a machine and having problem where would like it to use the base default location (/tmp/krb5cc_uid (because setting up kerberos for a specific piece of software that expects it to be right there)) for cached credentials (see http://web.mit.edu/kerberos/www/krb5-1.9/krb5-1.9.4/doc/krb5-admin.html#The-User_002fKerberos-Interaction)...

The name of the credentials cache can be specified in the ‘KRB5CCNAME’ environment variable. If this variable is not set, the name of the file will be /tmp/krb5cc_uid, where uid is your UNIX user-id, represented in decimal format.

However, finding that whenever stat a new terminal session, the KRB5CCNAME variable is always set, which overwrite the base location setting (see https://web.mit.edu/kerberos/krb5-1.12/doc/basic/ccache_def.html#default-ccache-name)

The default credential cache name is determined by the following, in descending order of priority:

1. The KRB5CCNAME environment variable. For example, KRB5CCNAME=DIR:/mydir/.


2. The default_ccache_name profile variable in [libdefaults].


3. The hardcoded default, DEFCCNAME.

So whenever logging into a new terminal session, seeing

$echo $KRB5CCNAME
KEYRING:persistent:<my uid>

Does anyone know how I can do this or what other info should be provided to improve this question (completely new to kerberos-anything, so info here may not be complete)?
