Commit Message

Arne Schwabe July 22, 2021, 11:43 p.m. UTC 
The problematic behaviour happens when start a profile without
auth-user-pass and connect to a server that pushes auth-token
When the auth token expires OpenVPN asks for auth User and password
again.

The problem is that the auth_user_pass_setup sets
auth_user_pass_enabled = true; This function is called from two places.
In ssl.c it is only called with an auth-token present or that
variable already set. The other one is init_query_passwords.

Move setting auth_user_pass_enabled to the second place to ensure it is
only set if we really want passwords.

Patch V2: Remove unrelated code change
