The type of credential cache can be + controlled with this option. The supported values are: + <parameter>KCM</parameter> or <parameter>KEYRING</parameter> + (when supported by the system's Kerberos library and + operating system), + <parameter>FILE</parameter> and <parameter>DIR</parameter> + (when the DIR type is supported by the system's Kerberos + library). In case of FILE a credential cache in the form of + /tmp/krb5cc_UID will be created - in case of DIR you NEED + to specify a directory which must exist, the UID directory + will be created in the specified directory. + In all cases UID is replaced with the numeric user id. + Check the details of the Kerberos implementation.</para> + + <para>When using the KEYRING type, the supported mechanism is + <quote>KEYRING:persistent:UID</quote>, which uses the Linux + kernel keyring to store credentials on a per-UID basis. + KEYRING has limitations.
