Allow authentication request on the F5

Hello,

 

I have an reverse proxy entry. This entry redirects flows on a server which manage an authentication via a popup (authentication supports by the server and not the F5). But, the F5 seems not allow these authentication flows. So I can't access to the server. I see something with the client authentication but I'm not sure about that.

 

Someone can help me ?

 

Thanks a lot in advance.

 

Best regards,

 

Agathe

    Hi,

     

    But, the F5 seems not allow these authentication flows. : Why do you say that? did you investigate what's wrong?

     

    what authentication is configured on the server? pop-up authentication can be

     

    • basic
    • NTLM
    • Kerberos

    Basic authentication won't have any issue with F5 between client and server

     

    NTLM can have some issues if Oneconnect profile is enabled on the VS and NTLM profile not enabled. I also got some issues if Analytics profile enabled with javascript injection... I was not sure the issue was chunking issue.

     

    If Kerberos is used, make sure your kerberos configuration is compatible with load balancing (per application SPN, not per machine, ...)
