Volker, does ccache impose a start-up penalty? Some libsmbclient
applications are "one-shots"; they start-up, do their thing, and then exit.
I'm not sure we'd want to impose a start-up penalty on those apps.

In any case, this could be configured by a parameter in the global smb.conf
and, specifically for libsmbclient, on a per-user basis in ~/.smb/smb.conf
(a replacement for the global one) or ~/.smb/smb.conf.append (applies after
applying the global one). smbc_setOptionUseCCache() could be called with the
value read from the config file, as is done in libsmb/libsmb_context.c for
the workgroup:

                char *workgroup;

                if (lp_workgroup()) {
                        workgroup = SMB_STRDUP(lp_workgroup());
                smbc_setWorkgroup(context, workgroup);
