    Description

    In the firmware 12.1.0, we see that the User Domain part is stripped down through using userPrincipalName as the user name attribute

    For Example, We see in the policy server logs: 

    ssl1 ps 100004fb Debug 1 System AUTH: UNPW-AD :getDnAndGroupsAndAttribsOfUser(): userID: [testuser]
    ssl1 012688 ps 100004fb Debug 1 System AUTH: UNPW-AD :getDnAndGroupsAndAttribsOfUser(): uidAttr: [userPrincipalName]
    ssl1 012688 ps 100004fb Debug 1 System AUTH: UNPW-AD :getDnAndGroupsAndAttribsOfUser(testuser): search filter: [(userPrincipalName=testuser)]
    ssl1 012688 ps 100004fb Verbose System AUTH: UNPW-AD :LDAP: searching with base: [dc=mycompany,dc=com], filter: [(userPrincipalName=testuser)]

    Where ssl1 is the node name; testuser is the user name; mycompany.com is the user domain.

    Expected result should be testuser@mycompany.com

    This may cause Authentication failure

    Cause

    Appliance Extraweb is stripping the domain part when user is trying to authenticate.

    Resolution

    When you have UserPrincipalName as username attribute for authentication, you need to configure the below CEM for Activesync/OA authentication to work.

    Please follow the below process to apply the configuration extension on the Aventail Management Console.

    1. Log in to AMC.
    2. Click on Maintenance in the left-hand navigation menu.
    3. In the URL, append "?advanced=1", and hit return.
    4. Click on Configure under the new section Configuration extensions.
    5. Click New
    6. For the Key field, put in: EW_ASYNC_STRIP_DOMAIN
    7. For the Value field, put in: false
    8. Click OK.
    9. Click Save,
    10. Apply Changes (this will force an apply-all, making the changes take effect).
    11. Click on Apply All and again Apply the Pending Changes.

    Please contact SonicWALL technical support at 1-888-793-2830 if you have any questions. It is adviced to make this change with the guidance of the technical support.

    Note: Applying this change will cause all the services to be restarted. Please schedule a window for this change.
