# [Plugin: W3 Total Cache] Rackspace Cloud Xcache authorisation issue…

 * When using Rackspace Cloud’s XCache when saving the options a username and password
   is requested.
 * I contacted Rackspace about this and they have issued the following:
 * The reason the plugin requires the Admin auth is to flush your site related cache
   from the xcache which you do not have authentication to.
 * The flag you mentioned:
    xcache.admin.enable_auth = Off/False/0 Cannot be overwritten
   in our environment because of that restriction.
 * Since we manage the caching environment for xcache we would systematically manage
   these files.
 * So unfortunately leveraging this part of the plugin is not customizable.
 * Frederick – I’m not sure if this might help with a fix for this but currently
   for me to admin my WP site I have to turn Xcache off. As clearing it each time
   causes the username and password box to appear.
 * And as I cannot provide one my changes are never saved.
 * Best,
 * Adam

 * You’ll have to work with RackSpace to address this. Setting the username and 
   password to empty may help however.

 * Where would I set the username and password?

 * I was told by Rackspace Support that the XCache empties every 2 minutes & that
   it depends on how you set your TTL’s on Expiry Headers which determines the length
   of cache on files/media etc…
 * Just set it to Opcode (XCache) but never actually empty it because Rackspace 
   are doing it periodically every 2 minutes apparently.

 * Your right [@adskiremote](https://wordpress.org/support/users/adskiremote/)
 * It’s impossible to use XCache since you cannot make any updates to settings or
   page content without getting the XCache empty page cache popup dialog… I think
   Disk/Enhanced Disk is the best you are going to get on Shared Platform for reasons
   of security & because the way W3 Total Cache has been designed.
