How do I configure Outlook Web Access 2000/2003 using Form Authentication? .: 3SP Knowledgebase

Outlook Web Access (OWA) can be configured to use Form based Authentication. When this mode is activated the user must login to OWA through a HTML form rather than through integrated HTTP authentication.

SSL-Explorer can be configured to automatically log the user into this form. The following steps describe how to configure an OWA web forward for Forms based authentication. This assumes you are using an Active Directory user database for SSL-Explorer authentication.

1. Create a new Reverse Proxy web forward.

2. Set the Destination URL field to https://mail.example.com/exchweb/bin/auth/owaauth.dll, where mail.example.com is the hostname of your OWA server.

3. Enter the required paths for your OWA installation into the 'paths' text area:
/exchange
/exchweb

4. On the authentication details page, select POST as the Form Authentication Type.

5. Add the following entries to the Form Parameters field.
flags=0
trusted=0
SubmitCreds=Log On
username=DOMAIN${session:username}
password=${session:password}
destination=https://sslexplorer.example.com/exchange

(where sslexplorer.example.com is the FQDN of your SSL-Explorer server. Once the user has authenticated, their browser will be redirected to this location. It is important that the user uses this URL to access SSL-Explorer otherwise errors may occur. Similary the DOMAIN value in the username parameter should be changed to the NetBIOS name of your Active Directory domain)

6. Assign the resource to a suitable policy and exit the resource wizard.
