Setting RenewTickets does not respect existing cache file settings

[macsux]

Setting RenewTickets seems to "forget" cache configuration of the client and revert back to default cache location. Code used:

            var client = new KerberosClient(config, loggerFactory);
            client.CacheInMemory = false;
            client.Cache = new Krb5TicketCache(options.CacheFile);
            client.RenewTickets = true;

after the last line runs, the cache is no longer pointing to what is specified in options.CacheFile.

That's certainly odd. The client.RenewTickets property just sets client.Cache.RenewTickets which is not used at all in Krb5TicketCache. I suspect that line is a red herring. I believe what's happening is KerberosClient.SetupCache() is being called when client.Cache is geted, which is querying the client-wide configuration for it's cache path.

	break;

	default:
	this.SetFileCache(path);
	break;
	}

I recently did an overhaul of how the client instantiates the cache. Can you see if this repros for you anymore?
