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.
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.
