VPN – SonicWall SSL VPN with Both AD and Local Users

It may be small comfort, but it’s working for us. The server is Windows Server 2003 R2 and the SonicWALL has SonicOS Enhanced 4.2.0.1-12e.

Here are the settings:

• Authentication method for login: LDAP + Local Users
• LDAP Server tab:
  • Chose “Give bind distinguished name”
  • Bind distinguished name: sonicwall_ldap@OURDOMAIN.local (a user we created to allow the SonicWALL to read LDAP)
  • Use TLS (SSL) checked
    • Send LDAP ‘Start TLS’ request: checked
    • Require valid certificate from server: unchecked (we use a self-signed cert)
    • Local certificate for TLS: None
• Did not configure RADIUS as a fallback.

Now, before your logins will work you have to go to the Directory tab and click “Auto-configure.” If auto-configure fails, make sure the SonicWALL’s LDAP username and password (e.g. sonicwall_ldap@OURDOMAIN.local) is correct.

After doing auto-configure make sure “Trees containing user groups:” includes the section of your AD tree that has the users who will be logging in. Once you do that, on the “Test” tab you should be able to test with:

• User: username (Note:**AD domain name should **not be included in the username because the SonicWALL will search the user contexts that were specified on the Directory tab).
• Password: (their password)

This seems like a pretty straightforward walkthrough:
