The curl command was just a try - I need to configure the authentication information in
"secure_vars.yaml". Somehow I've got to select the authentication profile -
eg. "internal" for "admin@internal" or "Domain" for auth
with AD User.
But this is only an assumption, since during the installation there's an according
"Error during SSO authentication access_denied : Cannot authenticate user
'xxx(a)xxxxx.LOCAL': No valid profile found in credentials.."
That error message corresponds to the error when I try to authenticate with curl.
The login on the webinterface however works - but there's an dedicated option (drop
down menu) for selecting the profile.
