Error connecting to AppFabric Cache Cluster with an account that contains a $ in the username

Hi there,

I'm having a strange behavior when trying to connect to AP cache cluster confinguration (Connect-AFCacheClusterConfiguration) with an account that has a $ symbol in username.  I think that it is the reason of my problems in SharePoint 2013 with the distribute cache service.

In powershell when I try to make a connection using the account $app-emea-pi10farm, I get this error:

PS > Connect-AFCacheClusterConfiguration -ProviderType xml -ConnectionString\\SM-FRMO-VCAS004\CacheConfigShare
Connect-AFCacheClusterConfiguration : Could not find a part of the path 'C:\Users\4168app-emea-pi10farm\AppData\Local\Temp\2\DCacheAdministration2013-02-28-135435[4168].log'.

Obviously, this path doesn't exist, the one that exist is C:\Users\$app-emea-pi10farm\AppData\Local\Temp\2\DCacheAdministration2013-02-28-135435[4168].log

Any ideas or workaround about this?

Thanks!
