    NTLM cache and intermittent NTLM authentication issues

    mmalagni

      All,

       

      I'm having some problems with NTLM authentication.

       

      I have 2 appliances load balanced by an external load balancer.

       

      The traffic between the 2 is split eavenly.

       

      FIRST appliance:

      SECOND Appliance:

      Another strange thing is that sometimes, only on few machines, I have authentications pop up on clients logged in to the domain.

       

      I tried to enable debug logging for authentication on the second appliance and the result is I've seen lots of the following errors:

       

      Authentication didn't return values, failure ID: 0, authenticationfailed: 0

      Authentication didn't return values, failure ID: 8, authenticationfailed: 0

      Authentication didn't return values, failure ID: 4, authenticationfailed: 0
