[BUG] Cannot post to default location

[hulleyg]

Describe the bug
Once the extension was installed and the configuration was performed within ckan.ini. The user cannot login via SSO. Receive and Internal error after the saml query. Looking at the web browser diagnostic options, the folder /acs is not available Error 500.

ckanext-saml2auth version affected
v1.1.0

Expected behaviour
The post occurs and the correct info is pulled into the require parameters to create the user if that user is not present or login.
Where should this directory be created within the system? Are there any other options that are required in the ckan.ini file? This is installed on Ubuntu 22.04
