Title:
  installer of 21.04 not allowing to use dot symbol in AD administrator
  username

Status in ubiquity package in Ubuntu:
  Triaged
Status in ubiquity source package in Impish:
  Won't Fix

Bug description:
  So I just tried to install ubuntu 21.04 and checkout how new Active Directory integration works.
  During installation I checked options to use Active Directory features and on next screen I has ben asked to enter AD domain name and AD administrator credentials.

  In my users in ad always have dot symbol in their logins e.g. j.doe,
  administrators also, but installer displays error message and not
  allowing enter my administrator user credentials.

  I think is a bug cause Active Directory has no restrictions for dots
  in usernames.
