After enabling CAC WUI authentication, you are logged out of the LoadMaster WUI. Please close the web browser and open it again. Then, attempt to log in with a valid certificate.

The WUI authentication login is based on CAC X.509 certificates. Authentication systems vary depending on the type of system, such as Active Directory or another access control list.

When logging into the LoadMaster WUI with CAC and LDAP, the username needs to be fully qualified, that is, it needs to be the UserPrincipalname or <Domain>\<Username>.
