How to Restore LDAP or Azure AD Directory Services

  • Last updated on

LDAP Authentication

If you previously set up LDAP authentication with your Barracuda Email Security Service account, your settings are not lost when you select Azure AD for a selected domain. Note, however, turning off Azure AD disables Single Sign On (SSO) and new users are not synchronized; recipient verification continues to function.

To restore LDAP settings:

  1. Log in to https://login.barracudanetworks.com/ using your account credentials, and click Email Security in the left pane.
  2. Click Domains, and click Edit in the Settings column for the affected domain. 
  3. In the Domains > Domain Settings page, click LDAP in the Directory Services section.
  4. In the Turn Off Azure AD dialog box, click Turn Off to disable Azure AD.
  5. Allow the LDAP Configuration Settings test to complete.
  6. The LDAP test results display. Click OK to close the dialog box.
  7. Your LDAP Configuration is restored.

Azure Active Directory Authentication

To restore Azure Active Directory (AD) authentication:

  1. Log in to https://login.barracudanetworks.com/ using your account credentials, and click Email Security in the left pane.
  2. Click Domains, and click Edit in the Settings column for the affected domain. 
  3. In the Domains > Domain Settings page, click Azure AD in the Directory Services section.
  4. In the Disconnect LDAP dialog box, click Disconnect LDAP Directory to disable LDAP.
  5. Click Save Changes at the top of the page.
  6. In the Status section, click Authorize.
  7. The Authorize Azure AD dialog box displays. Click Continue.
  8. When prompted, log in to your Microsoft Office 365 account using your administrator credentials.
  9. In the Authorization page, click Accept to re-authorize Barracuda Email Security Service to connect to your Azure AD directory.
  10. The synchronization progress displays; allow the process to complete.
  11. The Synchronization Options section displays based on your original setup. When Automatic is selected, the Barracuda Email Security Service automatically synchronizes with your Azure AD directory every two hours and adds/updates your users.
