Dell PowerStore Configuring Multiprotocol File Sharing

The Windows credential is only built or retrieved when a user, using an NFS request, attempts to access a file system that has a Windows access policy. The UID is extracted from the NFS request. There is a global Windows credential cache to help avoid building the credential on each NFS request with an associated retention time. If the Windows credential is found in this cache, no other action is required. If the Windows credential is not found, the UDS or local file is queried to find the name for the UID. The name is then used (optionally, with ntxmap) to find a Windows user, and the credential is retrieved from the Windows DC or LGDB. If the mapping is not found, the Windows credential of the default Windows user is used instead, or the access is denied.
