Alternative location for credential cache directory

Use this policy to control the adclient.krb5.ccache.dir configuration parameter. For details, see adclient.krb5.ccache.dir

The adclient.krb5.ccache.dir parameter specifies the directory where Kerberos ccache files are stored when krb5.cache.type is FILE.

This is useful when kerberos applications in docker containers use the kerberos cache files. This parameter, in conjunction with adclient.krb5.ccache.dir.secure.usable.check enables volume bind mapping so that kerberos cache files in the host OS are available to the docker containers.
