This can be done with CIFS shares that are on-premises, for example NAS, SAN or Windows Filers, where access is required out of the office or for remote working and/or it can be used to provide access to hosted SMB shares such as Azure Files or Amazon FSx.
  
 The connector binds Identity and Access Management from the Enterprise File Fabric (integrated via Active Directory / LDAP integration) with the permissions of the underlying file shares to provide users with secure access into the SMB storage, whilst ensuring that users only see and access data that they have permissions to from the underlying shares.  The connector binds Identity and Access Management from the Enterprise File Fabric (integrated via Active Directory / LDAP integration) with the permissions of the underlying file shares to provide users with secure access into the SMB storage, whilst ensuring that users only see and access data that they have permissions to from the underlying shares.

 +The multi-user connector was added in v1906.07 of the File Fabric and is only available in the appliance version. Further enhancements and updates have been added to the multi-user connector in the 1906.08 service pack release. This should be considered the current pre-requisite service pack to deploy the connector.

 +If you have not already configured at least one LDAP authentication system for the organization then it is possible to complete the provider configuration without specifying an authentication system for the provider.  In that case organization members may have read access to the provider and its contents.

 +Starting with v2106, companies who use SAML as an authentication mechanism can use SAML with the SMB Multi-user  and Nasuni Connectors.  See [[https://docs.storagemadeeasy.com/cloudproviders/saml_for_nasuni_and_smb_mu|this page]] for more information.

 +<WRAP center round tip 100%>
 +Because this connector imports and applies access permissions in a way that prevents direct control in the File Fabric, some of the File Fabric's behaviours may differ from the behavior with other connector types.

   * By design, this connector cannot be added by individual org members to create personal providers as it involves creating a Shared Team Folder for the organization's users.   * By design, this connector cannot be added by individual org members to create personal providers as it involves creating a Shared Team Folder for the organization's users.
   * For each SMB provider that you add, you will find a shared team folder created in the root of the Organization account. The File Fabric reads the permissions for the file shares, whether you are mounting the root of a file share, or if you are mounting a sub-path of the share. Where DFS is fronting the shares, all users will have access to the DFS root, and the shares within the DFS server will have permissions applied accordingly.   * For each SMB provider that you add, you will find a shared team folder created in the root of the Organization account.

-  * If a user receives the message "Password not found for user. Please re-login", they are advised to log-out and re-login again. This occurs when shares are added after users have begun authenticating.

-For guidance in adding, modifying, or deleting configuration parameters, [[appliance/editing-config|please follow our guide here]].+  * You must add this connector using the Organization Administrator account, not a 'delegated admin' account.
  
 +* The baseDN that you specify for LDAP searches must be high enough in the tree to encompass both all of your users and all of your shares.  Use the domain name as the baseDN or, if you are using another entry at the baseDN, ensure that all  groups for your shares are within the baseDN that you select.
  
 +* If the password of a user who is using the File Fabric's desktop tools to access storage via this connector changes, she must log in via the web to cause the password to be refreshed, preventing mount errors. As of appliance 2106, end-users will be automatically logged out when passwords on Active Directory if the configuration option on the Authentication System is enabled to check for password changes. 
  
 +* Share names configured in the File Fabric must match the corresponding names on the storage exactly, including case. If the cases differ then you will experience errors when adding the provider.
 +
 +* When a folder is being configured as the root of a share, the full folder path configured in the File Fabric must match the path on the storage exactly, including case.  If there are differences in case then the File Fabric will not be able to fetch and use the storage's access control information.
 +
 +* When a user's permissions to access a folder are changed on the storage, that change will not be reflected in File Fabric's metadata until the File Fabric has refreshed its view of the folder.  This may lead, for example, to brief periods when a user appears to continue to have access to a folder's contents although the user's access has been removed from the storage.  The storage's permissions will apply, however, if the user attempts to access the contents of the folder during this brief period.
