LDAP Authentication
If you previously set up LDAP authentication with Email Gateway Defense, 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:
- Log into https://login.barracudanetworks.com/ using your account credentials, and click Email Gateway Defense in the left pane.
- Click Domains, and click Edit in the Settings column for the affected domain.
- In the Domains > Domain Settings page, click LDAP in the Directory Services section.
- In the Turn Off Azure AD dialog box, click Turn Off to disable Azure AD.
- Allow the LDAP Configuration Settings test to complete.
- The LDAP test results display. Click OK to close the dialog box.
- Your LDAP Configuration is restored.
Azure Active Directory Authentication
To restore Azure Active Directory (AD) authentication:
- Log into https://login.barracudanetworks.com/ using your account credentials, and click Email Gateway Defense in the left pane.
- Click Domains, and click Edit in the Settings column for the affected domain.
- In the Domains > Domain Settings page, click Azure AD in the Directory Services section.
- In the Disconnect LDAP dialog box, click Disconnect LDAP Directory to disable LDAP.
- Click Save Changes at the top of the page.
- In the Status section, click Authorize.
- The Authorize Azure AD dialog box displays. Click Continue.
- When prompted, log into your Microsoft 365 account using your administrator credentials.
- In the Authorization page, click Accept to reauthorize Email Gateway Defense to connect to your Azure AD directory.
- The synchronization progress displays; allow the process to complete.
- The Synchronization Options section displays based on your original setup. When Automatic is selected, Email Gateway Defense automatically synchronizes with your Azure AD directory every two hours and adds/updates your users.
