The explicit Reader assignment is a lower share-level permission than the configured all-authenticated-user Elevated Contributor default. Azure Files does not treat a more specific lower-privilege assignment as an overriding deny in this configuration. Expecting Reader to reduce the default would give the wrong result; to impose read-only access, the administrator must redesign the default and specific grants.

Azure Files does not inherently reject a user just because two applicable share-level permissions overlap. Its documented rule selects the higher share-level permission among the default and the specific RBAC grant. An actual deny could still arise from network, authentication or NTFS constraints, but no such conflict is described here; deleting assignments is not the required explanation.

Azure Files SMB still applies share-level authorization before directory and file ACL checks. NTFS Modify cannot simply eliminate the Azure share-level access decision, and an ACL alone cannot substitute for an appropriate share permission. In this case both layers permit modification, but the effective share-level permission comes from the higher Elevated Contributor grant rather than from the folder ACL itself.

Windows NTFS access-control lists are evaluated in the identity-authenticated SMB model. This workload is mounted using Azure Files NFS, whose client access is governed by permitted network paths and POSIX identity and permission semantics, not Windows ACL inheritance. Applying NTFS rules to the NFS directory will not fix the mismatch between the authentication models.

Storage File Data SMB Share Contributor is a share-level Azure role for SMB file access; it does not translate to an NFS caller’s POSIX identity or permissions. Removing NFS directory access would make legitimate Linux operations more likely to fail. Confirm trusted network access, the UID/GID mapping, and POSIX mode bits on the NFS path instead.

Joining or registering a Linux computer with Microsoft Entra does not cause an NFS mount to negotiate SMB Kerberos. The selected protocol remains NFS, and the service does not use the SMB per-user identity authorization path for these requests. This choice confuses directory registration with the separate authentication model that the file protocol actually supports.

Storage File Data SMB Share Contributor authorizes ordinary changes to file contents and directory entries over SMB but does not include modifying Windows ACLs. The administrator can therefore edit documents yet still receive access denied when changing security descriptors. Reassigning precisely the same role cannot add the permission-modification capability that the scenario lacks.

Storage File Data Privileged Reader is intended for reading file data while bypassing applicable ACL restrictions, not granting the ability to change those ACLs. It may look attractive because the word privileged suggests elevated access, but its read-only data actions do not authorize the requested permission administration. Use a role with explicit modify-ACLs rights instead.

Storage File Data SMB Share Reader provides basic read-only file-share access. It neither authorizes ordinary content updates nor enables Windows ACL changes, so assigning it would reduce rather than repair this administrator’s capability. The failure is an absent share-level modify-permission action, not a need to grant a reader role to the existing share.

The scenario already establishes successful AD DS Kerberos authentication to this Azure file share. Renewing an already-valid Kerberos service ticket does not create a missing Azure RBAC share-level role assignment. Check effective share-level grants for the appropriate synchronized identity.

Windows ACLs govern file and directory access after share-level authorization. Full Control at a file path cannot bypass a missing Azure Files share role when granular Azure RBAC is used. The two permission layers must both allow the intended operation.

Ordinary Windows file-server share permissions are not automatically created as Azure Files share-level Azure RBAC assignments. An optional migration cmdlet can help translate root-folder permissions, but it does not eliminate the need for an effective Azure Files role assignment in this granular-RBAC design.

The Reader role on an Azure resource group permits inspection of management-plane resource metadata. It does not issue Kerberos tickets, authenticate an SMB session, or grant the per-user data permissions needed on Azure Files. A cloud-only identity needs a supported file authentication method and appropriate share plus file authorization, not visibility into the storage account resource.

Using a storage account key can open a share, but that key is a shared, powerful secret rather than a per-user identity assertion. Giving it to every workstation makes access difficult to attribute and revoke independently and unnecessarily increases key exposure. The organization specifically needs identity-based SMB access for cloud-only users, which an account key does not provide.

A Blob user-delegation SAS is used to authorize specific Azure Blob service operations over HTTP, with its own resource and signature constraints. It is not a Kerberos ticket and cannot authenticate a Windows SMB UNC session to Azure Files. Even a SAS with broad Blob permissions would not establish the required file-share identity model or replace share-level access controls.

Changing an unrelated Blob container to public access affects anonymous HTTP reads of Blob data, not which principals exist in a Microsoft Entra Domain Services managed domain. It would also expose data without helping the group obtain SMB Kerberos authentication. The failure arises at the scoped directory identity boundary, not at Blob container visibility or access tier configuration.

Group-based scoped synchronization deliberately limits the users and groups copied into the managed domain; it does not automatically include every group assigned an Azure RBAC role. Members of excluded groups may have cloud identities and correct role assignments but still lack managed-domain credentials or membership needed for SMB. Review the selected synchronization groups and allow time for resynchronization.

Identity-based Azure Files SMB does evaluate share-level Azure RBAC roles in supported configurations; those roles remain distinct from the domain authentication and NTFS ACL layers. Saying roles never matter would overlook the explicitly configured group assignment. The administrator must resolve the missing synced identity first, then ensure the group actually has the expected share authorization.

Owner on the Azure VM is a management-plane authorization over the virtual-machine resource, not an Active Directory Kerberos credential. Granting it might allow VM configuration changes but would not restore DNS, routing, or contact with the AD DS key distribution center. The SMB file endpoint being reachable does not imply that this separate domain-authentication dependency is healthy.

Blob anonymous-access settings affect whether uncredentialed HTTP callers can read blobs; they do not participate in authenticated Azure Files SMB negotiation. Changing them would not repair DNS or network reachability to the domain controllers and could weaken confidentiality elsewhere. The relevant dependency is the Kerberos/AD DS path used by this already domain-joined client.

Increasing the share quota addresses file capacity and potential write failures after a successful connection. It cannot help the client locate or contact an AD DS controller to obtain a Kerberos service ticket. The failure occurs before normal file operations and is explicitly linked to broken directory DNS and routing, not a full share.

SMB Multichannel is supported on SSD Azure file shares, not HDD shares. Moving the dataset to HDD would lose this feature rather than add the parallel SMB connections the workload needs. Media-tier changes also affect cost and performance, but they do not repair a transport-channel bottleneck by themselves.

Storage Account Contributor provides account management-plane permissions, not additional SMB network sessions or throughput. It would grant excessive privileges to file clients and bypass the principle of least privilege. Channel negotiation depends on the client and Azure Files SMB support, not management RBAC scope.

Azure Files supports SMB 3.1.1 and can use multiple channels for supported SSD file shares. Anonymous blob access is a different object API and would remove identity-aware SMB file semantics and NTFS authorization. Switching protocols isn't a suitable remedy for an already authenticated SMB application's channel count.

A data-plane share role may be necessary after connection is established, but it cannot repair a TCP timeout before SMB authentication. Allow the supported SMB egress path to the File endpoint first.

Changing credentials does not establish a TCP path. The connection fails before authentication, so the blocked network route to TCP 445 is the immediate problem.

Share soft delete is a recovery feature and does not change SMB transport or the outbound firewall rule. TCP 445 must be reachable using the approved path.

FileStorage accounts are specialized for premium Azure Files shares rather than the combination of standard Azure Files and ordinary Blob services requested here. They may be appropriate when the main requirement is dedicated premium file performance, but selecting one would not provide a general-purpose standard account for both workloads. The storage-service mix determines the account kind.

BlockBlobStorage is optimized for premium block Blob workloads, not a shared standard account hosting Azure Files shares. It could serve some high-performance object-storage applications but lacks the requested ordinary multiprotocol service combination. The requirement for SMB file shares, as well as block blobs, rules out this specialized blob account type.

Azure managed disks expose block devices attached to virtual machines. They do not create Blob service containers or standard Azure Files SMB shares under one general-purpose storage account. Although disks store application data, the protocols and consumers are different. Provision a StorageV2 account instead of substituting a VM disk for two network storage services.

Blob containers store object data accessed through Blob APIs and SDKs. They do not present the managed block device that a VM operating-system disk requires, nor do they become a supported OS disk merely because the application runs on a VM. Use a managed disk attachment and snapshots rather than an arbitrary blob path.

Azure Files SMB shares serve files over a network connection and can support shared-folder workloads, but they are not VM-attachable managed OS disks. An SMB share cannot replace the block-storage device used by the hypervisor for boot and low-level disk I/O. File sharing is useful separately from the VM’s managed-disk requirements.

A storage account access key authorizes calls to supported storage services but does not provision any VM disk capacity, IOPS tier, or attachment. Possession of a key is a security credential, not a block device resource. The workload must create and attach a managed disk resource to obtain the requested storage behavior and snapshot support.
