# Managing Active Directory Configuration in VAST Web UI

To manage an existing Active Directory configuration in VAST Web UI:

1. From the left navigation menu, select User Management and then Active Directory.
2. In the Active Directory page, right-click an existing Active Directory configuration and choose one of the following actions:

| Action | Description |
| --- | --- |
| SMB allow | Allows VAST Cluster to use this Active Directory provider to authenticate and authorize clients accessing the cluster via the SMB storage protocol. |
| SMB disallow | Prohibits use of this Active Directory provider for SMB client access. |
| NTLM enable | Allows use of NTLM authentication for SMB clients to get authenticated via this Active Directory provider. > [!TIP] > Tip > > Before enabling NTLM, leave the cluster's joined Active Directory domain. After NTLM is enabled, rejoin the domain. |
| NTLM disable | Prohibits use of NTLM authentication for SMB clients to get authenticated via this Active Directory provider. > [!TIP] > Tip > > Before disabling NTLM, leave the cluster's joined Active Directory domain. After NTLM is disabled, rejoin the domain. |
| Join | Click to let VAST Cluster join the Active Directory domain specified in the configuration record. |
| Leave | Click to let VAST Cluster leave the Active Directory domain to which it has joined. |
| Show -> Domains | Displays each of the discovered Active Directory domains with indication of the domain's fully qualified domain name (FQDN), search base DN, and security identifier (SID). For more information, see [Viewing Discovered Domains](/docs-5-4/docs/en/viewing-discovered-active-directory-topology#viewing-discovered-domains). |
| Show -> Joined Domain DCs | Displays all DCs from all domains in the discovered forest of the cluster's joined domain. For each DC, it shows its URI, status (such as HEALTHY or FAILED), and whether it is on the same Active Directory site as the cluster. For more information, see [Viewing Discovered DCs of the Joined Domain](/docs-5-4/docs/en/viewing-discovered-active-directory-topology#viewing-discovered-dcs-of-the-joined-domain). |
| Show -> Global Catalog | The display shows the URI of the Active Directory global catalog (GC) server that is currently used by the cluster and the time to the next global catalog refresh (in seconds). Following is a list of other discovered GC servers. For more information, see [Viewing Discovered Global Catalog Servers](/docs-5-4/docs/en/viewing-discovered-active-directory-topology#viewing-discovered-global-catalog-servers). |
| View | Displays the Active Directory configuration. |
| Edit | Opens the Active Directory configuration for editing. |
| Delete | Deletes the Active Directory configuration from the VAST cluster. |
