"""
* remote user authentication backend
* remote user middleware
Note: SSOwat/nginx add authentication headers:
'HTTP_AUTHORIZATION': 'Basic XXXXXXXXXXXXXXXX='
'HTTP_AUTH_USER': 'username'
'HTTP_REMOTE_USER': 'username'
Basic auth contains "{username}:{plaintext-password}"
and we get SSOwat cookies like:
'HTTP_COOKIE': 'SSOwAuthUser=username; '
'SSOwAuthHash=593876aa66...99e69f88af1e; '
'SSOwAuthExpire=1609227697.998; '
* Login a user via HTTP_REMOTE_USER header, but check also username in:
* SSOwAuthUser
* HTTP_AUTH_USER
* HTTP_AUTHORIZATION (Basic auth)
* Create new users
* Update Email, First / Last name for existing users
