             Summary: Per-compute-service credential store
                 Key: JCLOUDS-1321
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-1321
             Project: jclouds
          Issue Type: Bug
          Components: jclouds-core
    Affects Versions: 2.0.2
            Reporter: Svetoslav Neykov


With a shared credential store (the current default) the configuration of one 
compute service leaks in all others, causing the wrong credentials to be used 
when not overridden.

The particular problem this fixes - [Azure sets default username/password for 
images|https://github.com/jclouds/jclouds-labs/blob/master/azurecompute-arm/src/main/java/org/jclouds/azurecompute/arm/AzureComputeProviderMetadata.java#L98]
 which leaks to other providers (through 
[GetLoginForProviderFromPropertiesAndStoreCredentialsOrReturnNull|https://github.com/jclouds/jclouds/blob/master/compute/src/main/java/org/jclouds/compute/config/GetLoginForProviderFromPropertiesAndStoreCredentialsOrReturnNull.java#L51]),
 causing the wrong username/password to be used.
Even if the credentials are scoped to a specific provider in the map, it still 
will cause cross-talk between differently configured compute services. The 
cache should only apply to the current compute service.
