Form authentication issue with dot separated domain

[rzenere_avvale]

Hi everyone,

are you aware on any issue with dot separated domains and Form authentication?

E.g. ql.ik\testUser

With that user and Form authentication I'm not able to login at all (and I'm given the message that the user is not recognized).

I'm on Qlik Sense 3.1 SR4, and can't find what is the issue with this specific domain.

Modifying the Virtual Proxy back to "Windows", and using the same credentials I can login without problems.
