Deploying scimify with SCIM 2.0 templates

Local configuration

Download scimify from GitHub and upload it in the public directory of your local web server (the path to the scimify should look in the end like /var/www/public_html/scimify)
Create a MySQL database and add the configuration details (database username, database password, database host and database name) under {path_to_scimify}/resources/config.php in the constant definitions
Start ngrok from command line (eg. ngrok http 80) and copy the https link under Forwarding link sections
Append to this URL the path to scimify and then /scim/v2 (for example https://abcdef.ngrok.io/scimify/scim/v2); this will be the value for Base URL in Okta

In your Okta preview tenant, navigate to Admin and hover over Developer Console present in the top left corner of the page and select Classic UI; this will change the administrative interface used
Navigate to Applications >> Add Application and search for "SCIM 2.0 Test App" (any of the options available will work)
Name your application as preferred under Application label and then select Next
Select Done; the Sign On Methods present on this page and in the application are placeholders and do not require any configuration
Once redirected to the application, select Provisioning tab, click on Configure API Integration >> Enable API Integration and add the base URL copied earlier (eg. https://abcdef.ngrok.io/scimify/scim/v2) in SCIM 2.0 Base URL section; for credentials you can add any values as scimify will not check them
After the credentials are saved, the provisioning options will be enabled
Under Provisioning tab >> To App, click Edit and enable Create Users, Update User Attributes, Deactivate Users and, optionally Sync Password, saving the values at the end by pressing Save

When a provisioning event occurs from Okta to scimify, you will be able to see it in ngrok by navigating in the browser to ngrok's web interface available at http://127.0.0.1:4040

If you would like to reset scimify to test new scenarios, simply drop the tables scimify creates (memberships, resources, resource_attributes and resource_schemas) and, at the first request, they will be automatically recreated
